SERVICE

Do not attempt to service

PPI

products yourself. Performing exploratory surgery on your audio equipment yourself will void the warranty. All parts of your

PPI

gear have been built to our specifications. These parts are not

made available to any unauthorized

PPI

dealer nor are they for sale. Our

goal is to make sure that your

PPI

product will always perform as good as

the day it was purchased. Contact your authorized

PPI

dealer about obtain-

ing any warranty service through

PPI

. (See Warranty inside back cover.)

CAUTION!

The extended use of a high powered audio system may result in hearing loss or damage. While

PPI

systems are capable of "Concert Level" volumes, they are also designed for you to enjoy at more reasonable levels all of the creative expressions made by musicians. Please stay seated while driving and observe all local sound ordinances.

The following formula is a guide to determine current draw so you can choose the proper gauge power cable and fuses for your system. A 50% amplifier efficiency rating is used as an average.

(Total 4-Ohm rate RMS output x 2) x 2 = Total Input Wattage

Total Input Wattage/Supply Voltage = Current Draw (in Amps)

Example:

Your

PPI4240

is 30 watts x 4 RMS @ 4-Ohms.

You would use the formula below:

30 x 4 = 120 watts Total Output

120W x 2 = 240W Input/12.5v = 19.2 amps Current Draw

Note: Notice that the total power is multiplied by two. This compensates for the 50% efficiency of the amplifier. When you drop your impedance in half you double the amperage.

125 - 150 2 2 2 2 0 0 0 0

Note: The ground wire should be the same size as the power wire.

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 "Smokey." Reconnect the negative terminal only after all connections have been made.

You will need to install an in-line fuse or circuit breaker in the power wire within 18” of the batter y. This fuse or circuit breaker protects your vehicle from fire in case the power wire shorts to the vehicle body.

Remote Turn-on

Your head unit should have a lead marked ‘remote’ or ‘ power antenna’ which will be used to turn on your amplifier. Extend this lead through your vehicle along with your RCA signal wires. Strip 1/4 inch of the insulation off the wire and insert the end into the corresponding terminal on the amplifier.

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. Terminate the ground wire with a ring connector and attach it to the bare metal using a #8 sheet metal screw and washer or preferably , a bolt, nut and a star washer (not supplied). We suggest crimping and soldering this connection. After the connection is complete, coat the area (on both sides) with silicone or some similar material to prevent rust from developing on the bare metal. If your grand total current draw is over 50 amps (or total output power is over 300 watts), you should run a ground wire beside your power wire from the battery to the amplifier(s) in addition to your regular ground wire. Keep the ground and power 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. Once you have run both the power and ground wires, it's time to connect the cables to the amplifier. Cut off excess wire and, using wire strippers, strip the ends of the power and ground cables approximately 1/4 inch. Locate the power and ground connectors on the amplifier. With a small phillips head screw driver, loosen the screws before to you insert the cables. Insert the wires into the appropriate hole, and tighten the screws. The Power/Ground/Remote will accommodate 8 gauge wire for the

PPI4240

and the

PPI5440.

Speaker Wires

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. Loosen the four outer screws on the top of the connector. Insert the speaker leads into the end. Check to be sure you've maintained proper polarity before securing each wire, and tighten the screws on the amplifier.

1. Battery Power

Connect the 12-volt constant power cable from the battery here.

2. Remote

Connect the remote turn on lead from you source unit here. This connection will turn the amplifier on when the source unit is powered up.

3. Ground

Connect your ground wire here. Make sure you use the same gauge wire as your power cable.

4. Power LED

The LED will light up “GREEN” when the amplifier is powered on and “RED” when it goes into protection.

5. Speaker Terminals

Insert your speaker cable here. Insert speaker wire into LEFT (+) and RIGHT (-) for bridging.

6. Subwoofer Speaker Terminals

Insert the speaker cable for your subwoofer here.
