BOSS Audio Systems BAB8 8 800 W Powered Car Subwoofer Single 4 Ohm Voice Coil
A built-in amplifier powers the 8-inch subwoofer. No need to have a subwoofer housed in a box AND a separate amplifier. If you have a small cabin to work with, the BAB8 will provide the rich bass that every sound system cannot do without. A wired remote subwoofer control at your fingertips gives you control, so when the need hits.
