S ervice
Do not attempt to service PrecisionPower products yourself. Performing exploratory surgery on your audio equipment yourself will void the warranty. Many parts of your PrecisionPower gear are custom built to our specifications. Our factory parts are not made available to anyone else nor are they for sale. Our goal
is to make sure that your PrecisionPower product will always sound as good as the day it was purchased. Contact your authorized PrecisionPower dealer about obtaining any warranty service through PrecisionPower.(See Warranty inside back cover)

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 power distribution block near your amplifiers to keep the wiring tidy.

WIRING
The following is a basic formula to be used as a guide to determine amperage draw. A 50% amplifier efficiency rating is used as an average. Your new POWERCLASS™ amplifier is more efficient, other amplifiers will probably be less. This formula is to be used as a guideline. Using wire of a larger gauge can only improve the current transfer of your system. Do not use smaller gauge wire.
Total RMS output x 2 = Total Input Wattage
Total Input Wattage = Current Draw (in Amps)
Supply Voltage
Example: A POWERCLASS™ 2200 amplifier has two channels at 50 watts per channel RMS rating into 4 Ohms (50 + 50 = 100). You would use the formula in the following way:
100W x 2 = 200W
200W = 16.7A Total amperage draw.
12V
If the same amplifier is driven into a 2 Ohm stereo or 4 Ohm mono load, double its 4 Ohm RMS rating. All POWERCLASS™ amplifiers will effectively double their power at this load.
100W x 2 x 2 = 400W
400W = 33.3A Total amperage draw.
12V
If you are using more than one amplifier, add up the total amperage draw for all of them and choose the appropriate gauge based on the grand total.

WIRING
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.
Factory Ground wire may need to be replaced if it is frayed or broken.
Run signal cables (RCAs) and remote turn-on lead down the opposite side of the vehicle from the power wire to avoid radiated noise.
Avoid sharp edges that could chafe through the 
insulation.

Fuse must be installed within 18" of battery
Trk 1 |
Drill a hole in the firewall and use a rubber grommet to keep wire from shorting.
Run the cables under the carpet near the side of the vehicle. Be careful not to drill or screw into the wires when you replace the trim.
Firmly attach Amp Ground Wire to solid metal (see page 5).
