Rockville RVB12.1A 500W Active 12 Inch Car Subwoofer with Enclosure, Built-in Class AB Amplifier, Adjustable Crossover, Deep Bass, for Car Audio;

MORE BASS... LESS SPACE…FAST PACE.

The Rockville RVB12.1A is a 12" powered subwoofer that gives you everything you want out of a car subwoofer. This is a complete system with the subwoofer, enclosed in a box, along with a built in 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 the tight clean bass hits that 12" subwoofers are known to provide. I'm sure you also want the ease of a quick installation. With the RVB12.1A you will get it all. You will not have to do a separate amplifier and woofer installation. It's just one and done.

Our engineers used sophisticated computer modeling and created an enclosure for a 12" woofer that takes up less than 2.00 cuft (actually 1.8 cuft) and with a 15° sloped back the RVB12.1A will fit snuggly against the rear seat in your trunk and take up almost no room at all. Turbo tuned with an aerostyle port you will be astounded at the bass output this little bass enclosure produces. The aeroport 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 feel. 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!

Powered by a powerful built in Class AB 300 Watt RMS amplifier the RVB12.1A will keep you rocking with clean power. We also eliminated air or mechanical noises that you do not want to hear. This model features an electronic low pass crossover that is fully adjustable so that you can customize it for your car's listening environment (though we recommend keeping it at that low 45-60Hz range).
