MTX Audio RT8PT 8-Inch 240W Car Subwoofer Enclosure – Amplified Vented Tube Box

Meet the MTX Audio RT8PT, a compact, all-in-one bass solution designed to fit in virtually any vehicle without sacrificing trunk space. Don’t be fooled by its small footprint—the RT8PT combines an 8-inch high-output subwoofer, a built-in amplifier, and a vented enclosure to deliver deep, responsive bass that enhances today’s music across genres.

What sets RT8PT apart is the integrated 120W RMS amplifier. It powers the subwoofer cleanly while maintaining efficient heat management, thanks to a Class D design. You can connect it using either high-level or low-level inputs, giving you flexible compatibility with most receivers and factory radios. An external bass control is included, so you can tweak your preferred low-end response from near the driver seat; this is handy during daily commutes or weekend road trips when you want to adjust mood on the fly.
