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.
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.
Bandpass Crossovers in 250 Words or Less There are times when you would like to limit a speaker to a specific range of frequencies or sounds. A great example of this is a midrange. You don't want it playing very low frequencies that might damage it. Smoked voice coils smell terrible. To achieve this you need to use Bandpass crossover.

Now I'll introduce you to the controls on the XDi 1200.6. HIGHPASS With the crossover set in Highpass you will be using the highpass frequency control. In this case it is on the far left hand side how- ever this may very from model to model. If the crossover is set to FULL turning this control will not do anything.

AUTO DETECT SPEAKER LEVEL INPUT AUTO SENSE The XDi 1200.6 uses BTLD (Bridge Tied Load 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.
