The BOSS BAB8 subwoofer provides a unique solution for adding a low-end audio to your vehicle's sound system. The low-profile design makes it easy to install underneath a seat or in the back of a truck cab. Installation is a breeze when the amplifier and speaker are already combined in a finished speaker cabinet. With both high-level and low-level inputs this 800 watt subwoofer is the perfect addition to any vehicle's sound system.
