Your ampli er Does NOT make power. It converts power, or current, from your 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- er will produce Full output for longer then other amps on the market today.
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 con gurations all ARC Audio ampli ers 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.
Ohm Load Matching This ampli er is equipped with a unique impedance matching system that allows you to mix a wide range of Ohm loads and still achieve full power. This can be done independently on the front and rear channels. 2Ω...

AUTO DETECT SPEAKER LEVEL INPUT AUTO SENSE uses a BTLD (Bridge Tied Load) Auto Detect Turn-on circuit that offers a significant improvement in reliability over previous designs. Instead of relaying on the music to supply enough signal to turn the amplifier on. Robert Zeff’s design detects the IC (chip) used in the vast majority of stock head units and amplifiers.
