About this item

Product details

MAXIMUM BASS... LESS SPACE…FAST PACE.
The Rockville RVB8.1A is an 8" powered subwoofer that gives you everything you want out of a car subwoofer. This is a complete system with the subwoofer installed in to a heavy-duty vented enclosure, along with a built in high power amplifier. This sub system will give you more bass in your car or truck, without giving up tons of space to get it. I'm sure you want tight clean bass that hits with the ease of a quick installation. With the RVB8.1A you get it all, no need for a time consuming separate amplifier and woofer installation. Just drop it in and it’s done.
Our engineers used sophisticated computer modeling and created an ultra efficient bass enclosure for an 8" woofer that takes up less than 1.00 cubic feet. Combined with a 15° sloped back the RVB8.1A will fit snuggly against the rear seat in your trunk and take up almost no room at all. Turbo tuned with an aero style port you will be astounded at the bass output this little bass enclosure produces. The aero port is side mounted on the enclosure so the low frequencies get a chance to "load" in to your car trunk and the bass waves get a chance to fully develop before entering the passenger compartment. We are talking about low bass frequencies that you can actually fee; “infrasonic” bass. In most cases packaged systems put out weak bass that is not deep. Our Rockville subwoofer was engineered and tuned to put out the bass you can feel!
