Product details
Compact Bass with Big Impact – Orion XTR8US 8” Underseat Powered Subwoofer
When space is limited but you still crave deep, responsive bass, the Orion XTR8US steps in as the perfect solution. Designed for ultra-compact installations like under seats or behind panels, this all-in-one subwoofer system delivers up to 1000W of clean, punchy bass that enhances your driving experience without stealing your cargo space.
Small Size, Serious Sound
With a unique 8” woofer setup, the XTR8US may be small in footprint but it hits hard where it counts. It’s engineered to give your system the added low-end depth missing from factory audio, bringing your favorite music to life with richness and clarity. Whether you’re upgrading a commuter or a custom build, this underseat subwoofer delivers reliable performance with minimum installation hassle.
All-in-One Simplicity
No need for external amps or complex wiring, the XTR8US includes a built-in 250W RMS amplifier that’s pre-tuned for smooth performance. You get full control via bass boost, phase adjustment, and low-pass filter, plus a wired remote to adjust the bass from the driver’s seat. With smart features like auto-start and 4-way protection, it’s made to be easy, safe, and effective.
Engineered to Fit Anywhere
Crafted for stealthy installations, the XTR8US is housed in a rugged, low-profile enclosure that disappears under most car seats. With clean wiring, illuminated status indicators, and vibration-resistant construction, it’s the kind of install you set up once and enjoy every drive after.
