Remove retaining screw with a 2.5mm hex wrench
For the rear channels, locate the four terminal speaker PowerLockTM 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
soldering this connection. After the 
connection is complete, coat the area 
(on both sides) with silicone or some similar material to prevent rust from
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.
