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 prefer-
ably, 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 devel-
oping 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.
