Features & Benefits

6-Channel Multi-Zone Flexibility
Drive complete audio systems from a single amplifier installation. Allocate channels strategically: four channels for cabin coaxials, two bridged pairs for tower speakers at 200W each, or six channels for full cabin coverage with independent zone control. Perfect for ski boats requiring cockpit, cabin, and tower zones, or 4WD tourers with front cabin, rear cargo, and rooftop speaker zones. Eliminates the complexity and wiring bulk of multiple smaller amplifiers while providing professional-grade zone control.

12V Standard Electrical Integration
Designed for conventional 12V automotive and marine electrical systems (11-14.5V operating range). Integrates directly into factory or aftermarket head unit systems without voltage converters or special infrastructure. The 50A fuse rating and 4 AWG wire compatibility match standard marine and automotive electrical practices, simplifying professional installations and DIY builds alike. Compatible with AGM, lithium, or standard flooded batteries common in Australian recreational vehicles and vessels.

Independent Channel Control with Bridge Capability
Run all six channels independently at 75-100W each for maximum zone control, or bridge adjacent pairs (1+2, 3+4, 5+6) for three outputs at 200W each. Bridge mode suits high-output tower speakers, marine subwoofers, or demanding full-range speakers requiring more power than single-channel output. Mix configurations within the same installation: four unbridged channels for cabin speakers plus one bridged pair for subwoofer duty, providing system design flexibility without multiple amplifiers.

Marine-Rated Class D Topology
Conformal-coated circuit boards resist salt spray, bilge moisture, and the corrosive environments encountered in Australian coastal boating, offshore fishing, and beach-launched vessels. The robust construction handles tropical humidity in Far North Queensland waters, dusty corrugated tracks in the Outback, and Southern Ocean conditions off Tasmania. Class D efficiency minimizes heat generation, enabling reliable operation in poorly ventilated equipment bays, under seats, or in enclosed amplifier racks without thermal shutdown.

Variable Filtering Across All Three Channel Banks
Precision crossover control on channels 1&2, 3&4, and 5&6 allows speaker-specific tuning. High-pass filter cabin speakers to remove low-frequency strain and improve clarity, low-pass subwoofer channels for dedicated bass reproduction, or run full-range where needed. The 12dB/octave slopes and 50Hz-500Hz continuously variable range accommodate marine coaxials, component speakers, tower speakers, and compact subwoofers. Detented potentiometers enable repeatable settings across similar installations—critical for professional installers servicing multiple boats.

Compact Chassis with Professional-Grade Heat Management
At 260mm (10.23") wide and just 2.63kg, the XDM600/6 fits shallow-mount locations behind helm panels, under seats, or in equipment bays where larger amplifiers won't fit. The efficient Class D topology and well-designed heat sink maintain stable operation across all six channels simultaneously, even during extended listening sessions at anchor, beach parties, or long-distance highway touring. The compact footprint doesn't compromise thermal performance—essential for sustained full-power operation.

Optional Water-Resistant Remote Control
Add JL Audio's HD-RLC or MHD-RLC (not included) to adjust system volume from the helm, driver's seat, or entertainment area. Essential for marine applications where the amplifier is mounted in inaccessible equipment bays, or automotive installations where the amp is hidden behind panels. The remote provides convenient master volume control without accessing the installation location, perfect for recreational boaters and touring enthusiasts.

Frequently Asked Questions

Can I run this amplifier with a standard aftermarket head unit?
Only if your head unit or DSP provides six independent preamp outputs. Most standard head units offer 2-4 channels of preamp output—you'll need a 6-channel DSP or signal processor to feed all channels. Alternatively, use a marine source unit with 6-channel capability or run the amplifier with fewer active channels.

Can I bridge channels for higher power to tower speakers or subwoofers?
Yes. Bridge adjacent channel pairs (1+2, 3+4, 5+6) for 200W RMS per bridged pair at 4Ω load. This provides three bridged outputs at 200W each, ideal for marine tower speakers or compact subwoofers. Ensure speakers are rated for 4Ω minimum impedance when bridging. You can also mix configurations: bridge two pairs, leave two channels unbridged.

What size alternator do I need to run all six channels at full power?
Minimum 90A alternator for sustained full-power operation. At maximum output (600W), the amplifier draws approximately 60-65A from the electrical system. Factor in other electrical loads (navigation, pumps, lights) and ensure your alternator provides adequate reserve capacity. Undersized alternators cause voltage drop and potential thermal protection shutdown.

Can I use this in a ski boat with tower speakers and cabin speakers?
Yes, perfect application. Bridge channels 1+2 and 3+4 for 200W × 2 to tower speakers, use channels 5&6 unbridged for 75W × 2 to cabin speakers. Alternatively, run all six channels unbridged for complete cabin/cockpit coverage at 75-100W per zone. The variable filtering allows precise tuning for different speaker types and mounting locations.

How do I set up independent zone control for different areas?
Use channels 1&2 for Zone 1 (cabin), 3&4 for Zone 2 (cockpit/tower), and 5&6 for Zone 3 (rear/helm). The optional HD-RLC remote controls master volume. For true zone-independent control, install separate zone controllers or use a DSP with zone management feeding the amplifier. The three independent filter banks allow different crossover settings per zone.
