The Pioneer TS-WX400DA proves you don’t need a bulky box to get serious low-end impact. Built with a slim, underseat-friendly design and a down-firing rectangular driver, this compact subwoofer fits neatly into tight spaces while still delivering deep, satisfying bass. Whether you're working with a small cabin or just want a clean install, this setup keeps your system powerful without taking over your interior.
Inside, the efficient Class-D amplifier pushes out 100 watts RMS and 250 watts peak while staying cool and energy-efficient. You also get two bass personalities to match your vibe. Switch to Deep Mode for smooth and rich lows or go Dynamic Mode when you want harder hitting punch for hip-hop and EDM. The included wired remote puts full control within reach, letting you adjust gain, crossover from 50Hz to 125Hz, phase, and bass mode right from the driver seat.


Installation is straightforward thanks to the single harness wiring system and included cables, making the process cleaner and faster. With both RCA and high-level input support, it works seamlessly with factory or aftermarket head units. Adjustable input sensitivity ensures proper signal matching, while the included mounting brackets let you secure it under seats, in the trunk, or on a seatback. It is a simple way to upgrade your system with powerful bass and a professional, space-saving finish.
