FUSE REQUIREMENTS You will need to install an in-line fuse or circuit breaker in the power wire within 18” of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your fuse or circuit breaker. You may also want to add a powe

AMPLIFIER STATUS LEDS 1 2 The LEDs provide the following indications: 1. Power - These LEDs illuminates the center Precision Power logo background when the amplifier power is turned on. 2. Short - These LEDs behind the PPI logo will flash to indicate a short on the output. 2. Thermal - These LEDs behind the PPI logo will extinguish if the amplifier is in thermal shutdown protection. Note: Read the AP-IV Protection Circuit section for additional information regarding Short and Thermal protection.

WIRING Before beginning, disconnect the negative (-) terminal of the battery prior to connecting the amplifier to the positive (+) 12V terminal to prevent a short to ground and potential damage to wiring and equipment. Some vehicle radios have an anti-theft feature where when the radio is removed from 12V the radio will no longer function and must be code reset. Note: The cables running from the battery to the rear of the car should be installed on the side of the car opposite to the antenna. Wh

CHARGING SYSTEM If your total current draw is over 100 amps (or total output power is over 600 watts), you are probably exceeding the capability of your charging system. Dimming lights and fluctuating voltage are solid indicators that you need to upgrade your alternator, battery, or both. You should also check the condition and current capacity of the stock battery negative cable and connections, and replace or upgrade as necessary. Keep in mind that your amplifiers simply convert electrical ene

These amplifiers will effectively double their power at this load. 1000W X 1.5 X2 = 3000 watts 3000W = 250 Amps total current draw 12V If you are using more than one amplifier, add up the total current draw for all of them and choose the appropriate gauge based on the grand total. POWER WIRE SIZE A minimum of 8 gauge or a maximum of 4 gauge wire is recommended dependent on the application. The ground wire must be the same gauge as the power wire. 12

POWER LOCK CONNECTORS Once you have run both the power and ground wires, then connect the cables to the amplifier. Cut off excess wire, and using wire strippers, strip the ends of the power and ground cables TM approximately 1/4 inch. Locate the PowerLock power and ground connector (supplied). Using a hex wrench, loosen the screws before attempting to insert the cable wires. Insert the wires into the appropriate hole, and tighten the screws.

Deriving the mono channel is accomplished by using the Left Channel Positive wire (L+) as the positive speaker wire and the Right Channel Negative wire (R-) as the negative speaker wire. Note: It is important that a minimum 4 ohm impedance is observed. If the impedance drops below 4 ohms while the amplifier is wired in the bridged configuration, the amplifier’s protection circuitry may engage.
