Product Overview

The KENWOOD KSC-PSW88 delivers rich, deep bass in a compact footprint designed for under-seat installation in space-limited audio systems. As the direct successor to the KSC-PSW8, the PSW88 brings a fresh redesign and increased performance while retaining the ease of installation and integration installers rely on. This powerful subwoofer features 700W max power rating with 280W RMS output, providing substantial low-frequency performance for OEM upgrades or aftermarket audio system enhancement. The compact dimensions of 215mm width x 72mm height x 289mm depth enable installation under most vehicle seats without compromising passenger legroom or storage space. The included wired level controller allows convenient bass adjustment from the driver's seat, enabling fine-tuning of low-frequency output based on music genre, listening preference, or acoustic environment. Advanced features include adjustable bass boost control for enhanced low-end impact, phase control for optimal acoustic integration with existing speakers, low pass crossover for frequency management, input gain adjustment for signal matching, and multiple input options including high-level and RCA inputs. The amplifier section provides auto power-on functionality triggered by audio signal detection, remote control capability, and protection circuitry safeguarding against overheating and electrical faults for reliable long-term operation.

Frequently Asked Questions

Will this subwoofer fit under my vehicle seats?

The KSC-PSW88 is specifically designed for under-seat installation with compact 215mm x 72mm x 289mm dimensions that fit under most vehicle seats without compromising passenger legroom. The low-profile 72mm height enables installation in tight spaces where traditional subwoofer enclosures cannot fit, making it ideal for sedans, SUVs, and vehicles with limited trunk space.

How does the wired level controller work?

The supplied wired level controller mounts within easy reach of the driver's seat, allowing real-time bass adjustment without accessing the subwoofer amplifier. Simply rotate the control knob to increase or decrease bass output based on music genre, listening preference, or acoustic environment, providing convenient customization during operation without distraction.

What is bass boost and when should I use it?

Bass boost enhances low-frequency output by increasing gain at specific bass frequencies, providing increased impact for bass-heavy music genres or compensating for cabin acoustics that may reduce perceived bass. Adjust the bass boost control to match your musical preferences - increase for more impact with electronic or hip-hop music, or reduce for more natural bass response with acoustic recordings.

Can I connect this to my factory radio without RCA outputs?

Yes, the KSC-PSW88 features high-level inputs that accept speaker-level signals directly from factory radios without RCA outputs. Simply connect the high-level input harness to your existing rear speaker wiring, and the subwoofer amplifier automatically converts the speaker-level signal to appropriate line-level for processing, enabling installation in vehicles with factory audio systems.

What does the phase control adjust?

Phase control adjusts the timing relationship between the subwoofer and your existing speakers, ensuring bass frequencies combine constructively rather than cancelling each other. If bass sounds weak despite high volume, adjust the phase setting - proper phase alignment delivers fuller, more impactful bass by ensuring the subwoofer and speakers work together rather than against each other.
