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.

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.
5
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.

All
PPI
amplifiers are capable of being bridged into a 4-Ohm mono output without switches or bridging modules. This in turn allows you to run Full range or component speakers and a subwoofer off one
PPI
amplifier. (using
passive crossovers) You can achieve this mono channel by using the Left positive (+) speaker
connection and Right negative (-) speaker connection. You can bridge channels 3 and 4, on your
PPI
four channel amplifiers, in the same way.
(Refer to the end panel drawing on page 8.)
Your new
PPI
amplifier offers you the flexibility of mixed mono operation. This means you can operate each pair of channels in both stereo and mono mode at the same time. This is accomplished by using highpass filters (capacitors) on the higher frequency stereo channels, and a lowpass filter (coil) on the subwoofers. The frequencies of the chosen highpass and low­pass filters must not overlap (allow the mids and highs to play the same music as the subs) or the impedance the amplifier sees at those frequencies will be cut in half possibly causing it to go into protection.

1. Adjust all amplifier input gain controls to just above minimum sensitivity (fully counterclockwise).
2. Using the cleanest source (CD), with music playing turn up the head unit until you can hear the music begin to distort. Now turn it down a bit until you cannot hear the distortion.
3. Increase the Amplifier gain (clockwise) until the onset of audible distortion. Then decrease the gain to the point just before the distortion starts. This setting minimizes background noise and prevents overload.
4. Repeat step 3 for any remaining amplifiers in the system.
Your new
PPI
amplifier has one two-way built-in crossover. By using the ‘X-OVER’ switch on your amplifiers endplate, you are able to select either full range, high pass or low pass (FULL/HPF/LPF) for your ‘Speaker Output’. Using the ‘X-OVER FREQ’ control select the desired crossover frequency, 20Hz to 5kHz. Now it’s time to set the ‘OUTPUT X-OVER’ as FULL/HPF/LPF. The ‘OUTPUT’ will be whatever frequency you selected on the ‘X-OVER FREQ’ and either FULL/HPF/LPF depending on where you set the ‘OUTPUT X-OVER’.

For extra BOOM from your system, we’ve developed the
QBASS™
bass
control circuit. The
QBASS™
control is located to the left of the crossover switches and allows you to add up to 12dB of boost centered at 40Hz by rotating the control clockwise.
This circuitry is capable of eliminating noise radiated into your signal cables by up to 40dB. This is equivalent to a noise reduction of approximately one hundred times what the noise level would be without this circuitry. It provides all the benefits of a true ‘balanced’ line without the need of any special cables (see diagram below). This type of input works with any conventional RCA cable.
CAUTION!
QBASS™
should only be used in systems
with strong subwoofers. 12dB is a lot of bass boost and could
damage full range speakers.
