A BOSS Elite powered sub is the space-efficient way to bring some bang to your audio. These packages include a premium subwoofer driver and amplifier inside a sealed enclosure. You’ll get a bass speaker that had loud, accurate sound while easily fitting under the seat in compact cars or truck cabs. The BOSS Audio Systems Elite series of active subwoofers also costs way less than comparable premium brands. OnlineCarStereo.com has free lifetime tech support to help you enjoy the ride.
