High performance car audio amplifiers love lots of signal voltage. This allows them to deliver optimum sound quality and maximum bass response. Unfortunately, many of today’s after market source units don’t output the optimum voltage levels these amplifier need. The AudioControl OVERDRIVE PLUS pre-amp line driver increases the line level signals from aftermarket source units up to 13 volts max (9.5 RMS) and delivers them downstream to the amplifiers inputs. The results are increased dynamic range, maximum signal-to-noise levels, and tremendous bass response. Autosound enthusiasts will enjoy dramatically improved sound quality of their after market audio system.

The OVERDRIVE PLUS features an optional dash control input which facilitates remote control of pre-amp signal levels.  This makes the OVERDRIVE PLUS an ideal controller for overall system master volume (great for tablet installs) or subwoofer levels.
