Product description

Style:Under-seat subwoofer  |  Pattern Name:Subwoofer

The SS8P is an all in one solution to give you great sounding bass in your vehicle without taking up a lot of space. This sub enclosure is only 2.8" thick so that it can easily fit under your seat. The amplifier is built in, so installation and wiring is clean and simple. This is a true all in one subwoofer solution with the subwoofer built into the enclosure along with a top of the line amplifier built in as well.

We focused on making installation a breeze so we designed this unit with you the customer in mind. 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. Something else we did to make installation quick and easy 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 SS8P has 400 watts of peak power and 100 watts RMS. This has great controls so you can adjust the sound to your liking. It has a level control for the volume and subsonic filter to filter out the really low frequencies which the human ear cannot 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 but the best thing about our model is the sound. It is slim but it sounds like a full sized subwoofer If you are not happy with it we will offer you a 90-day money back guarantee. If you don’t like the sound, we will send you a pre-paid label and refund you in full!
