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 information below is a basic formula you can use to determine current
draw. A 50% amplifier efficiency rating is used as an average. Your new
PPI
amplifier is more efficient than most amplifiers, so others will probably
be less. This formula is only a guideline. Using wire of a larger gauge can
only improve the current transfer of your system. Do not use smaller
gauge wire.
Total 4-Ohm rate RMS output x 2 = Total Input Wattage
Total Input Wattage/Supply Voltage = Current Draw (in Amps)
Example: Your
PPI2360
has 2 channels @ 90 watts per channel RMS
into 4 Ohms (90 x 2 = 180). You would use the formula below:
180W x 2 = 360W/12.5V = 28 Amps Total Current Draw
Total Current Draw Length of Wire to Run (in Feet)
(in Amps) <3 <7 <10 <13 <17 <20 <22 <28
0 - 20 14 12 12 10 10 8 8 8
20 -35 12 10 8 8 6 6 8 4
35 -50 10 8 8 6 6 4 4 4
50 - 65 8 8 6 4 4 4 4 2
65 - 85 6 6 4 4 2 2 2 0

105 - 125 4 4 4 2 2 0 0 0
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 negativ e (-) 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 pr eferably , 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
PPI2120,
PPI2240,
and the
PPI2360.
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.
