Page 2: Introduction
Your amplifier Does NOT make power. It converts power, or current, from your cars electrical system and turns it into a high power musical energy. If the amp can't get all the power it needs it will not produce its full output. Your ARC Audio ampli- fier will produce Full output for longer then other amps on the market today. -
Page 3: Running The Cables
Running the Cables Carefully run the power and signal cables through the passenger compartment of the vehicle. Running power down one side and signal down the other is the preferred method. If this isn’t possible, keep them separated as much as possible. When running through any metal, always use a rubber grommet to prevent the power wire from shorting and to reduce the risk of fire. -

Gain Because of the wide range of head unit output configurations all ARC Audio amplifiers have an adjustable input sensitivity or “Gain” . The gain is not a volume or a power limiting control like a throttle. It makes the amp more sensitive to input from the stereo. -

Bass Boost This amp has an adjustable Bass Boost that is directed to the front speakers. When laying out your system, if you plan to use Bass Boost (Example: Running a Bridged Subwoofer), connect those speakers to the front channels. Begin your adjust- ments at a low volume. -
