The following is a basic formula to be used as a guide to determine current draw . A 50% amplifier ef ficiency rating is used as an average. Y our new POWER CLASS ™ amplifier is more ef ficient, other amplifiers will probably be less. This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer of [...]

Before beginning, disconnect the negative (-) terminal of the battery prior to working on the positive (+) terminal to prevent a short to ground. This is important, unless you want to spend the rest of your life with a nickname like "Sparky ," or "Smoke y ." Reconnect the negative terminal only after all connections have been ma[...]

Grounding Locate an area near the amplifier(s) that is metal and clean an area about the size of a quarter to bare metal. Inspect the area around and underneath to be sure you won't drill into wires, brake or fuel lines, etc. Drill a pilot hole in the middle of this area. T erminate the ground wire with a ring connector and attach it to the ba[...]

Cut off excess wire and, using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. Locate the P ower Loc k power and ground connector (supplied). With a small flat bladed screw d[...]

Using 16 gauge or larger , run the speaker wires from the amplifier location through the vehicle to the speakers. Observe the same precautions for routing these wires that you followed for running the power and remote turn-on wires. Cut off excess and, using wire strippers, strip 1/4 inch of insulation. Locate the speaker/remote turn-on P ower Loc [...]

Bridging Any or all pairs of channels (1/2, 3/4 or 5/6) on your POWER CLASS ™ multi channel amplifier are capable of being bridged into a 4 ohm mono output without switches or bridging modules (2 ohm mono on Channels 5/6). This feature permits the creation of a mono channel for a subwoofer or center channel. Deriving the mono channel is accomplis[...]
