Supplying Enough Power Congratulations! Thank you for purchasing an ARC Audio Hi-Performance Amplifier. The Laws of Nature Your amplifier Does NOT make power. It converts power, or current, from your cars electrical system ARC Audio amplifiers are conservatively rated and produce more power per channel and turns it into a high power musical energy. If the amp can't get all the power it needs it will not than others in there class. Manufactured to the highest standards of quality and produce

Input Section Bass Boost Because of the wide range of head unit output configurations all ARC This amp has a fully adjustable bass boost. Both the frequency and the Audio amplifiers have an adjustable input sensitivity or “Gain” . The gain level of the boost are adjustable. Start with a small increase in the level is not a volume or a power limiting control like a throttle. It makes the control. Then “sweep” the frequency up and down. Listen carefully for an amp more sensitive to input fro

Bridging Bridging Cont. Bridging is a way to combine the power of 2 channels into 1. When For bridging to work both amplifiers must be playing exactly the same you wire the amp bridged you have a higher voltage differential signal at exactly the same output level. To make this easier we have between + and -. That means MORE POWER. added a “Slave In” and “Slave Out” to this amp. When you use the Slave In all the gain and crossovers are bypassed. This eliminates all the compli- If you have 2

Installation Instructions 9. Connect the speaker wire to the amp and speakers (make sure 1. Disconnect the negative cable from the car battery. Tape up the end the amp is off first). Make sure the polarity (+ and-) is correct. so it is isolated form the battery. 10. Connect the RCA’s to the amp. 2. Run the power wire (4 AWG min.) from the battery to the amplifier. 11. Double check the amplifier controls at this time. Make sure Plan this part of the installation carefully. This cable
