For the rear channels, locate the four terminal speaker PowerLock
connector. Using a hex wrench loosen the screws on the upperside of
the connector. Insert the speaker leads into the end and secure with
the hex wrench. Check to be sure you've maintained proper polarity
before securing each wire.

GROUND WIRING

Locate an area near the amplifier(s) that is metal and clean an area
about the size of a quarter down to bare metal. Inspect the area
around and underneath to be sure you will not 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 preferable, a bolt, nut
and a star washer. (not supplied). We suggest crimping and
developing on the bare metal. If your grand total current draw is over
80 amps ( or total power is over 500 watts ). 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.
