Newly designed for vehicles that want to add some bass but have very little to no room for large subs and boxes.
The SQBASS68 incorporate a 6x8" Subwoofer in a compact enclosure that contains a special design to help extend and elaborate the bass for your music! This small unit can fit under most conventional car seating, rear cubby, or medium sized storage compartments so you can have clear and vibrant bass even if you have no room.
The unit also comes with it's own volume control input so you can find the perfect bass level for your musical preferences. With 150w RMS and 600w MAX power available on tap you will be sure to get goosebumps every time you hear the bass drop.
Highlights
- Add bass where there was none before easily! Compact and slim design that is made to fit under most front or rear seats or wherever there is room. The options are endless!
- Specially designed 6x8" subwoofer made to maximize bass response in spaces that are not typically designed for subwoofers.
- Built in high power amplifier with bass remote input. High level inputs and RCA inputs will ensure this will work for any vehicle. 150w RMS 600w max output has been engineered to power this under the seat sub and enclosure to it's most optimal output.
