NOTE: TOOLS ARE NOT SUPPLIED
Small flat blade screwdriver
Phillips screwdriver (#2 or medium sized)
Wire cutters Wire strippers
4 - #6 round head screws, and 1 - #8 sheet metal screw
(or nut, bolt,flat washer, star washer) [see detail]
2 - Ring connectors (large enough to accommodate your method of grounding)
In-line fuse or circuit breaker - see fuse chart below
Power and ground wire - see Power Wire Calculator on page 4
Speaker wire - 12-16 gauge
Grommets (sized to work with the power wire you plan to use in your installation)
Tube of silicone sealant
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 distribute large gauge power cable to multiple amplifiers.

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.
Warning! A Main Fuse must be installed within 18" of battery!

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 PowerLock power and ground connector (supplied). With a small flat bladed screw driver, loosen the screws before attempting to insert the cables. Insert the wires into the appropriate hole, and tighten the screws. Once the wires are secure, the PowerLock™ may be plugged into the amplifier. The Power/Ground PowerLock™ will accommodate 6 gauge wire for the PCX 440 and PCX 480, and 4 gauge wire for the PCX 4125 and PCX 5800.
