The Rockville RTB12A is a self-contained 12-inch powered subwoofer in a vented bass tube with a built-in 300W RMS amplifier. It adds low end to a factory or aftermarket car system without a separate amp or box, and its remote lets you trim bass from the driver's seat. It suits drivers who want more bass in a small space and don't want to build a custom enclosure. Against separate component subs it gives up some output and tuning flexibility, but it is simpler to install and takes up less room.

Owners describe the RTB12A as an easy way to add noticeable bass to a stock system, with the remote getting frequent praise. Some say the boost makes the bass muddy at high settings and that it needs careful tuning.
The Rockville RTB12A is a powered subwoofer bass tube with a 12-inch high-power woofer and a built-in 300W RMS amplifier. The amplifier and enclosure are combined in one unit, so no separate amplifier or enclosure is needed. It is intended for upgrading a car audio system.
The cylindrical vented enclosure has a rear aero port for tight, impactful low-end sound in a compact footprint. The tube is wrapped in aviation-grade tweed and has a molded steel grille.
It has both speaker-level and RCA line-level inputs, so it works with factory and aftermarket head units. An adjustable low-pass crossover and a bass boost EQ let you tune the sound. A dashboard-mounted bass remote controls bass output from the driver's seat. Steel mounting brackets and Velcro straps allow installation without permanent modifications.
