amplifier designed to handle virtually any car audio configuration with a single, compact unit. Rated at 100 watts RMS per channel at 2 ohms 400 watts total it's built for flexibility without compromise. Whether you're running a full 4-way front and rear speaker setup, a 3-way front-stage system, or bridging the rear channels to drive a pair of subwoofers, the P400X4 adapts to your build.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIts real strength lies in versatility. Drop component speakers on the front channels and a pair of subs on the rear bridged and you have a complete front-stage-plus-bass system from a single amp. The onboard Punch EQ with +18dB boost at 45Hz adds low-end weight without a separate processor, while the C.L.E.A.N. gain-setting system makes calibration straightforward regardless of your experience level. For Australian drivers running everything from daily commuters to long-haul tourers, the cast aluminium heatsink keeps the P400X4 stable through the heat.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eKey Specifications\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTotal RMS Output:\u003c\/strong\u003e 400 watts\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePer-Channel Output:\u003c\/strong\u003e 100W x 4 at 2 ohms\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBridgeable:\u003c\/strong\u003e Yes — rear channels bridgeable for subwoofer use\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCrossover:\u003c\/strong\u003e 12dB\/octave Butterworth\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOnboard EQ:\u003c\/strong\u003e Punch EQ — +18dB boost at 45Hz\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e High-level (speaker-level) and RCA\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAuto Turn-On:\u003c\/strong\u003e Yes — via high-level input detection\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTurn-On Behaviour:\u003c\/strong\u003e Muted (no thump on startup)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeatsink:\u003c\/strong\u003e Cast aluminium\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eControl Panel Position:\u003c\/strong\u003e Stealth top-mounted\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e Short circuit and over-current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHigh-Level Input with Auto Turn-On\u003c\/strong\u003e — Connects directly to factory head unit speaker outputs with no RCA cables required.

Run it in full 4-channel stereo for front and rear speakers, bridge both channel pairs into a high-power 2-channel configuration, or operate it in 3-channel mode with stereo speakers up front and a subwoofer on the bridged rear channels. The P600X4 handles all three without compromise.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhat sets the P600X4 apart from entry-level 4-channel options is its expanded feature set. RCA pass-thru outputs let you chain additional amplifiers as your system grows without resorting to Y-adapters that degrade signal quality. The optional PLC2 remote Punch Level Control adds a dash-mounted bass adjustment knob with a real-time clip indicator, and the variable HP\/LP Butterworth crossover gives you precise per-channel tuning for speakers and subwoofers alike. For Australian builds dealing with heat, corrugations, and long-distance touring, the cast aluminium heatsink and onboard protection circuits keep everything running cleanly.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eKey Specifications\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTotal RMS Output:\u003c\/strong\u003e 600 watts\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePer-Channel Output:\u003c\/strong\u003e 150W x 4 at 2 ohms\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 4 (stereo, 3-channel, or bridged 2-channel)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBridgeable:\u003c\/strong\u003e Yes — bridge both channel pairs for high-power 2-channel operation\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCrossover:\u003c\/strong\u003e Variable HP\/LP, 12dB\/octave Butterworth\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOnboard EQ:\u003c\/strong\u003e Punch EQ — +18dB boost at 45Hz\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e High-level (speaker-level) and RCA\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRCA Pass-Thru Outputs:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAuto Turn-On:\u003c\/strong\u003e Yes — via high-level input detection\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRemote Control:\u003c\/strong\u003e Optional PLC2 Punch Level Control (with input clip indicator)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTurn-On Behaviour:\u003c\/strong\u003e Muted (no thump on startup)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeatsink:\u003c\/strong\u003e Cast aluminium\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eControl Panel Position:\u003c\/strong\u003e Stealth top-mounted\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e Short circuit and over-current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHigh-Level Input with Auto Turn-On\u003c\/strong\u003e — Connects directly to factory head unit speaker outputs with no RCA cables required.

While the T400X2AD handles two channels, the T400X4AD extends this to four channels, making it the appropriate choice when all four speaker positions (front left, front right, rear left, rear right) need amplification from a single compact unit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA 2\/4-channel input switch is a key addition over the 2-channel model allowing the amplifier to accept either a full 4-channel input from four RCA connections or a 2-channel input that is internally split to drive all four output channels. This simplifies integration with headunits that offer only a 2-channel RCA output while still delivering amplification across all four speaker positions. High-level inputs with auto turn-on, Remote-Out, C.L.E.A.N. clip detection, top-mounted controls, dual fan cooling, and 4Ω bridged capability complete the feature set shared with the T400X2AD.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eKey Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePower output: 400W total (4-channel — rated power per channel at specific impedance not confirmed — see Red-flags)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAmplifier class: Class-AD (Rockford Fosgate proprietary)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eConfiguration: 4-channel\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eConstant Power: Yes — same output at 4Ω and 2Ω (multi-impedance)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e2\/4 channel input switch: Yes\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eBridged operation: Yes — 4Ω bridged capable\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eHigh-level inputs: Yes — with auto turn-on\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLow-level inputs: Yes (RCA)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRemote-Out: Yes — when using high-level inputs\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eC.L.E.A.N. input\/output clip detection: Yes — with LED indicators\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCrossover: Built-in (type\/slope not specified — confirm with Rockford Fosgate)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCooling: Dual fan forced induction + dual extruded heat sinks + real-time thermal sensing\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eControls: Top mounted\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePower\/ground connectors: 8 AWG\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRCA connectors: Upgraded\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e3-stage thermal lock extrusion: Yes\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDiscrete surface mount technology: Yes\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSignal-to-noise ratio: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTHD: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFrequency response: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDimensions: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWeight: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWarranty: Not specified — confirm with Rockford Fosgate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e4-Channel Output for Full Speaker Coverage\u003c\/strong\u003e — Amplifies all four speaker channels (front and rear left\/right) from a single compact unit — providing a full-vehicle speaker upgrade without requiring a second amplifier or a larger chassis.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e2\/4 Channel Input Switch\u003c\/strong\u003e — A key practical addition over the T400X2AD.

class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIn 2-channel mode, a single stereo (2-channel) RCA input is internally distributed to drive all four amplifier output channels — useful when the head unit has only a 2-channel preamp output. In 4-channel mode, discrete front and rear stereo inputs are used, allowing independent front\/rear level control. This makes the T400X4AD compatible with a wider range of head units without requiring additional signal processing.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eHow does the T400X4AD differ from the T400X2AD?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBoth amplifiers share the same Class-AD platform, feature set, and wattage. The T400X4AD provides four output channels versus two, and adds a 2\/4 channel input switch. The T400X2AD includes PLC2 remote compatibility — confirm whether the T400X4AD supports PLC2 remote operation with Rockford Fosgate if this is a requirement.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eHow does the high-level auto turn-on work with a factory system?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe high-level inputs accept signal from factory head unit speaker outputs and activate the amplifier automatically when audio signal is present — no remote turn-on wire is required. The Remote-Out then provides a 12V trigger for a downstream subwoofer amplifier or other accessories.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhat does C.L.E.A.N. clip detection help with during installation?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eC.L.E.A.N. (Circuit Level Evaluation And Normalisation) monitors both the input and output stages for clipping, with LED indicators for each. During gain setup, the LEDs identify when the signal clips — allowing the gain to be set at the maximum clean level. Correct gain structure is the most effective way to protect speakers from distortion damage and maximise sound quality.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eCan the T400X4AD be used in a bridged configuration?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes. Pairs of channels can be bridged to deliver higher output to a single 4Ω load — for example, bridging channels 1 and 2 for a front subwoofer or a single high-output speaker, while channels 3 and 4 continue to drive rear speakers in standard stereo configuration.

does it matter for full-range speakers?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eClass-AD combines the sound quality characteristics of Class-A amplification with the power efficiency of Class-D. Class-A designs are highly linear and produce very low distortion but are thermally inefficient. Class-D is efficient but involves switching-based operation that can introduce artefacts. Rockford Fosgate's Class-AD and its dynamic switching frequency control aim to deliver high-fidelity full-range performance with efficient power delivery — a meaningful advantage for component speaker systems that operate across the full 20Hz–20kHz range.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhat is dynamic switching frequency control?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDynamic switching frequency control is a technique where the amplifier dynamically adjusts its internal switching frequency based on the signal being amplified. This optimises linearity at each operating point, reducing the audible by-products of switching-mode amplification — contributing to the Class-AD's high-fidelity performance compared to standard fixed-frequency Class-D designs.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhat is the confirmed per-channel power output of the T1000-4AD?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe total rated power is 1,000W across four channels. Per-channel power at 2Ω and 4Ω is not confirmed in the supplier data — pull the official Rockford Fosgate T1000-4AD datasheet for the full power specification table, including per-channel RMS at each impedance.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eHow does the T1000-4AD differ from the T600-4?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe T1000-4AD delivers 1,000W total (vs the T600-4's 600W), uses Rockford Fosgate's Class-AD technology with dynamic switching frequency control, and is specifically designed for high-fidelity full-range use. Both include RCA pass-thru. The T600-4 uses a conventional MOSFET design. For audiophile-oriented builds where audio quality is the priority, the T1000-4AD is the appropriate choice.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eIs the T1000-4AD suitable for running subwoofers on the rear channels?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes. The 24dB\/octave crossover allows the rear channels to be configured in low-pass mode for subwoofer use. However, the T1000-4AD's primary design intent is high-fidelity full-range speaker amplification via Class-AD technology — for dedicated subwoofer channels, a Class-BD mono amplifier (T1000-1BDCP, T1500-1BDCP, T2500-1BDCP) connected via the RCA pass-thru is the more appropriate and more powerful solution.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":43055834857565,"sku":"T10004AD","price":2005.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/9528\/9437\/files\/T10004AD-1.jpg?v=1738732979"},{"product_id":"kenwood-kac-ps947-900w-performance-series-4-channel-amplifier","title":"KENWOOD KAC-PS947 900W Performance Series 4-Channel Amplifier","description":"\u003ch2\u003e\u003cstrong\u003e\u003cspan style=\"font-size: medium;\"\u003eAs Their Name Eludes, the KENWOOD Performance Series of Amplifiers Have Been Designed and Manufactured with The Power to Perform in Addition to Their Sleek Looks!\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eThe KENWOOD KAC-PS947 is a POWERFUL 4-channel bridgeable amplifier delivering 900 watts of power and featuring variable crossover speaker level input and cooling fans, perfect to boost the output of your front and rear speakers, a pair of subwoofer even shared between a the two!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eWhich ever way you go, rest assured you won't be disappointed with the results from this bad boy!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"font-size: medium;\"\u003eReliable Performer\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: medium;\"\u003eKENWOOD makes tough, rugged amplifiers that bring you superior sound quality along with reliable performance!

Powered by Boosted Rail Technology (BRT), an ultra-efficient proprietary power supply design, it generates 400 watts of total RMS output while keeping current draw low enough to suit trucks, sub-compact vehicles, electric vehicles, and hybrids where electrical system demand is a critical consideration. The amplifier operates at 4 ohm or 2 ohm stereo and 4 ohm bridged\/mono, with selectable fixed 12 dB\/octave Butterworth crossovers covering High-Pass and Low-Pass filter positions. A variable DC offset high-level input circuit with signal-sense turn-on simplifies integration with OEM head units and factory systems. MEHSA3 thermal management handles heat dissipation through an extruded aluminium heatsink, while real-time output and power supply thermal sensing monitors operating conditions continuously. The C.L.E.A.N. clip detection system uses a tri-colour LED indicator that identifies exact THD levels rather than just clipping events, giving a precise read on signal quality. Muted turn-on prevents transient noise through the speakers during power-up. CEA-2006 and CE compliant, with a 1-year warranty, designed and engineered in the USA.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBoosted Rail Technology (BRT):\u003c\/strong\u003e Rockford Fosgate's proprietary ultra-efficient power supply design generates 400 watts of output while minimising current consumption from the vehicle's charging system, making the PBR400X4D well suited to electric, hybrid, and sub-compact vehicles where alternator and battery capacity is limited.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eC.L.E.A.N.

full-range speakers across the front and rear channels, including the P1 and P2 coaxial and component speaker ranges. When bridged to 2-channel operation at 4 ohms, it can also serve as a compact, space-saving subwoofer amplifier in smaller builds. For systems requiring a dedicated subwoofer channel alongside speaker amplification, the onboard 80 Hz Low-Pass crossover option makes it straightforward to cross over rear channels to a subwoofer. Note that this amplifier uses 4-pin harness speaker connectors rather than standard terminal blocks; confirm harness compatibility with the installation vehicle before purchase. An 8-gauge amplifier wiring kit is required for power and ground runs.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat does Boosted Rail Technology (BRT) mean, and why does it matter for electric or hybrid vehicles?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBoosted Rail Technology is Rockford Fosgate's proprietary ultra-efficient power supply architecture used in the PBR400X4D. It generates 400 watts of output while keeping current draw significantly lower than a conventional Class AB amplifier of equivalent power. At 13.8V music, average current draw is just 27A, and the suggested alternator rating is 75A. This makes the PBR400X4D well suited to electric vehicles, hybrids, and sub-compact vehicles where the electrical system capacity is more restricted than a conventional petrol-powered vehicle.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDoes the PBR400X4D need a remote turn-on wire?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhen using high-level speaker inputs, no remote turn-on wire is required. The variable DC offset high-level input circuit detects the incoming speaker signal automatically and powers the amplifier on. When using RCA inputs, a standard remote turn-on wire from the head unit is required. Additionally, the Remote-Out feature provides a trigger output when the amplifier is running from high-level inputs, which can be used to activate downstream components.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat does the tri-colour output clip LED indicate, and how is it different from a standard clip light?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe PBR400X4D's C.L.E.A.N. output clip indicator uses three colour states rather than a simple on\/off clip light. Blue indicates the signal is clean at less than 0.5% THD. Violet indicates the signal is approaching the clip threshold at 1% THD. Red indicates the signal is clipping at 10% THD or greater. This tri-colour system allows gain to be set more accurately during installation without an external measurement tool.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAre the crossover points adjustable, or are they fixed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe crossover points on the PBR400X4D are selectable but fixed, not continuously variable. The High-Pass crossover can be set to either 60 Hz or 80 Hz. The Low-Pass crossover is fixed at 80 Hz. All crossovers operate at 12 dB\/octave Butterworth slope. For installations requiring precise variable crossover control, an upstream DSP such as the DSR1 would be needed.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat speaker connector type does the PBR400X4D use, and do I need a special harness?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe PBR400X4D uses 4-pin harness connectors for both front and rear speaker outputs rather than standard screw or compression terminal blocks. This is part of the compact, stealth-install design. Confirm that compatible 4-pin speaker harnesses are available for the installation vehicle or amplifier location before purchase, as standard bare-wire speaker connections are not supported directly on this amplifier.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":43059933904989,"sku":"PBR400X4D","price":492.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/9528\/9437\/files\/PBR400X4D-1.jpg?v=1738821000"},{"product_id":"infinity-primus6004a","title":"Infinity PRIMUS 6004A Compact 4-Channel 60 Watts RMS Car Amplifier","description":"\u003ch2\u003e\u003cspan style=\"font-size: medium;\"\u003e\u003cstrong\u003eInfinity PRIMUS 6004A Compact 4-Channel 60 Watts RMS Car Amplifier: Designed To Deliver Infinity’s Signature Sound In More Vehicles\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eInfinity Primus Amps are available in a variety of configurations, delivering the right power and number of channels for full-range and subwoofer applications.

For systems requiring low-end support, the rear channels bridge cleanly to drive a single Prime R1 subwoofer such as the R1S410 or R1S412, with the rear crossover set to Low-Pass.

The R2-300X4 supports 3-channel configuration, where the front channels power a pair of full-range speakers and the rear channels are bridged to drive a single subwoofer. Setting the rear crossover to Low-Pass rolls off high frequencies to the sub. The minimum impedance of any bridged channel is 4 ohms, so confirm subwoofer impedance before bridging.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDoes the R2-300X4 require a remote turn-on wire?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhen using RCA inputs, a remote turn-on wire must be connected to the head unit's remote output.

The two amplifiers chain together cleanly for a complete 4-channel speaker plus mono subwoofer car audio system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat does the 2\/4 channel input selection switch do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe input selection switch configures the R2-500X4 to accept either a 2-channel or 4-channel input from the source unit, working for both RCA and high-level connections. In 2-channel mode, the single stereo RCA pair feeds all four channels internally. In 4-channel mode, separate front and rear RCA pairs are used for independent left\/right front and rear channel control.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat fuse does the R2-500X4 require and is it included?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe R2-500X4 requires an 80A fuse, which is not included and must be sourced separately. This is smaller than the 120A fuse required by the R2-750X5 and R2-750X1, reflecting the R2-500X4's lower maximum current draw of 59A.
