Dual subwoofer System

The active/passive 2-1/2" driver scheme supplies low end rumble for the bass in your music or audio tracks. Working together, these two driver units put out more bass than a single driver would by itself.


Easy to use amplifier built-in

The built-in amplifier not only powers the dual subwoofer system, but it will also power a stereo pair of speakers once connected to the gold-plated 5-way binding posts. Other features include independent bass and master volume controls. Audio source connection is simplified with a single 3.5mm AUX input. This amp also comes equipped with a grounding cable, which may be necessary for some installation scenarios. If not, then it can be easily removed. The entire system is powered by a 15V 4A DC power supply (Sold Separately).
