Kenwood

You bought a smaller car — great gas mileage, but the sound system is just not cutting it! Kenwood made their KSC-PSW8 powered subwoofer to deliver impressive bass in less space. This compact powered enclosure fits under the seat in most vehicles, where it produces bass response that's equal to that of a larger subwoofer in your trunk. It offers a great solution for those who want to reinforce their low-frequency punch without losing a lot of room. This Kenwood gives you impressive bass from a truly compact enclosure with an 8" woofer. The rigid enclosure eliminates rattles, while the durable built-in amplifier feeds the speaker 150 watts RMS. Kenwood also includes a wired remote, so you can control the bass from the driver's seat. A wiring harness and mounting brackets are also included.
