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

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 battery. This fuse or circuit breaker protects your vehicle from fire in

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

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.)

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 o

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. CAUTION! QBASS™ should only be used in systems with strong subwoofers. 12dB is a lot of bass boost and could damage full range speakers. This circuitry is capable of eliminating noise radiated into your signal cables by up to 40dB. This is equivalent to
