Congratulations! Thank you for purchasing an ARC Audio Hi-Performance Amplifier. ARC Audio amplifiers are conservatively rated and produce more power per channel than others in there class. Manufactured to the highest standards of quality and reliability to deliver years of listening enjoyment. ARC Audio…SOLID CONSTRUCTION for SOUND Car Audio Systems. Warning We build all ARC Audio products to play at high volumes for extended periods of time. Your ears however are not designed for high volume listening.
Input Section 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. With the gain up the amp will reach full output at a lower volume setting on the deck. At higher gain settings the amp also becomes more sensitive to noise from the car’s electrical system.
Bridging Bridging Cont. Bridging is a way to combine the power of 2 channels into 1. When you wire the amp bridged you have a higher voltage differential between + and -. That means MORE POWER. For bridging to work both amplifiers must be playing exactly the same signal at exactly the same output level. To make this easier we have added a “Slave In” and “Slave Out” to this amp. When you use the Slave In all the gain and crossovers are bypassed.
Installation Instructions 1. 9. Connect the speaker wire to the amp and speakers (make sure the amp is off first). Make sure the polarity (+ and-) is correct. 10. Connect the RCA’s to the amp. 11. Double check the amplifier controls at this time. Make sure everything is set correctly for your system. 12. Now you’re ready to play it for the first time. It is best to leave the gain all the way down at first. Start with the head unit volume low and work your way up. 13. Now you can tune the amp.

4 OHMS BRIDGED In this configuration you can “Bridge” 2 amplifiers into 1 channel. To bridge 2 amps you must set amp 1 to “Normal” and amp 2 to “Slave”. All adjustments will then be made to amp 1.
