The USS8 is an all in one solution to give you great sounding bass in your vehicle without taking up a ton of space. This sub enclosure is only 2.9" thick so that it can easily fit under your seat. The amplifier is built in, so installation and wiring is easy and clean. This is a true all in one subwoofer system with the sub in the enclosure, and a top of the line amp built in.

We wanted to truly make installation a breeze so we designed this unit with the user in mind from start to finish. We added high level inputs so you can install this to an aftermarket or factory system. The high level input allows you to install this even if you have no preamp outputs available.

The smart turn-on circuit will sense that an audio signal is present and turn on the amplifier. When you turn off your music signal the amplifier built into this subwoofer system will automatically turn itself off.  

Another thing we did to make installation a breeze is we put all the inputs and outputs on one side. This makes wiring neater and easier. Our competitor’s models are more challenging to install.

The USS8 has 600 watts of peak power and 150 watts RMS. This model is CEA-2006 compliant which means the ratings are approved by a 3rd party so you can be 100% sure that this item will produce the power it says it will. This is one of the only slim under seat subs on the market that is CEA compliant. Do not get fooled by other brands who write bogus power ratings that do not comply with any industry standard. Even if another unit says 2000 watts on it, ours is better and louder

This has amazing controls so you can tweak the sound to your liking. It has a level control for the volume and subsonic filter to filter out the really low frequencies that the human ear can not hear. This also has a low pass crossover filter, phase control, input sensitivity, and bass boost.

Included is a remote bass knob, and mounting hardware.

Rockville owns the exclusive mold we designed for this enclosure. Our designer made a modern design that we think everyone will love. Some of the other ones on the market just weren’t pleasing to the eye. We paid extra money and made the mounting feet extra strong and thick. Other models on the market by cheaper brands have flimsy feet that tend to break easily.

The best thing about our model is the sound. It is slim but it sounds like a full sized sub. Our engineers spent the last 2 years developing this model. We put a lot of hours into this!

We know our product is the best under seat sub on the market. We will offer you a 90-day money back guarantee. If you are not happy with the sound, we will send you a pre-paid label and refund you in full.
