Our take on the RW68CA

The Rockville RW68CA is an all-in-one powered car subwoofer built around a 6x8-inch driver in a cast aluminum enclosure just 2.8 inches tall. It packs a built-in amplifier rated 100W RMS (400W peak) with a 50–180Hz low-pass filter, 0–12dB bass boost at 45Hz, a 20Hz subsonic filter and 4-ohm impedance. Its slim footprint lets it slide under most seats, and high-level inputs plus smart turn-on let it hook to a factory or aftermarket stereo without a separate amp. It suits drivers of small cars, trucks and older vehicles who want added low end without giving up cabin or trunk space.

About the RW68CA

The Rockville RW68CA is a slim powered car subwoofer with a 6x8" driver and a built-in amplifier. It stands 2.8" tall and is made to fit under a car seat. The enclosure is cast aluminum, and the unit weighs just under 10 lbs.

It has 400 watts of peak power and 100 watts RMS. High-level inputs let it connect to a factory or aftermarket stereo, and a low-level RCA input is also included. A turn-on circuit senses an audio signal and switches the amplifier on, then turns it off when the signal stops. All inputs and outputs are on one side of the enclosure for easier wiring.

Controls include level, low pass crossover, phase, input sensitivity and bass boost, plus a subsonic filter. A remote bass knob is included. Protection circuits cover thermal, short and overload conditions.
