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.

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. When using 16 gauge wire 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- TM on PowerLock conne

Note: The amplifier comes with the connector inserted into the amplifier with the wire clamping screws in the up position as shown below. Use a 2mm hex head wrench to secure the wires to the connector. If the connector needs to be unplugged from the amplifier, use a 2.5mm hex head wrench to remove the retaining screw from the connector (set aside and save the retaining screw).The two negative outputs are common to each other as are the two positive outputs. A speaker may be connected to either t

wires as close together as possible, and use the same gauge wire for both. This will ensure that you have a good ground path, and may eliminate such potential problems as engine noise and overheated amplifiers. 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.

375W = 31.25 Amps total current draw 12V If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, double it’s 4 ohm RMS rating. These amplifiers will effectively double their power at this load. 250W X 1.5 X2 = 750 watts 750W = 62.5 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 recommen

POWERLOCK 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. The Power/Ground TM PowerLock will accommodate 4 gauge
