The Epicenter Plus
Bass Restoration Processor With Aux Input
Adding impactful bass to your factory installed system is simple with The Epicenter® Plus. The added OEM Interface on The Epicenter Plus converts your speaker-level signals into high quality pre-amp outputs to give you More Bass, LOUDER! Plus, you get an auxiliary input for adding secondary sources (like iPods and Satellite Radio).
The high-impedance Speaker Level Inputs allow you tap off factory speaker leads for simple addition of aftermarket subwoofers to any factory audio system. AudioControl’s exclusive GTO™ Signal Sense Turn-on and corresponding 12-volt remote output provide the turn-on lead for aftermarket amplifiers. In addition to speaker-level inputs, The Epicenter Plus has line-level inputs for use with aftermarket systems.
The Epicenter Plus uses AudioControl’s famous Digital Bass Restoration to drive your subwoofers lower, grabbing the attention of every ear on the boulevard.
