This connection turns on the amplifier when you turn on the auto sound sys- tem, and turns off the amplifier when you turn off the auto sound system. This prevents your vehicle’s battery from being drained if you leave your amplifier on when you turn off your auto sound system.

If your auto sound system does not have a switched power lead, connect the blue/white wire’s other end to a point in your vehicle’s fuse block that has power only when you turn on the ignition or turn the key to ACC.

This connection turns on the amplifier when you turn on the ignition or turn the key to ACC, and turns off the amplifier when you turn off the ignition. This pre- vents your vehicle’s battery from being drained if you leave your amplifier on when you turn off the ignition.

6.Use a screwdriver to connect the spade end of the supplied red power cable (with in-line fuse holder) to the ampli- fier’s + 12V terminal.

7.Connect the other end of the red power cable to your vehicle’s positive (+) bat- tery terminal. Then tighten the terminal.

Caution: Due to the amplifier’s high cur- rent requirement, you must connect the red power cable’s fused end directly to the vehicle’s positive (+) battery terminal or damage to your vehicle’s wiring could result.

Do not reconnect your vehicle’s negative (–) battery cable yet.
