Section 6: Wiring In the Updated Amplifier Modules

This section gives the steps needed to wire the new modules into your old amplifier.

Here's the plan:

1. Build and install the Power Wiring Harness

2. Build and install the ground wiring harness.

3. Replace the left-channel input wiring.

4. Connect all the wires to the amplifier modules.

5. Fasten the amplifier modules in place.

1. See Figure 20. Cut the supplied black-red (18 AWG) pairs into two 12 inch

lengths. Strip ½" of insulation off of the ends of all the wires (8 places). Separate

the red and black wires for about 5" at one end, as shown in the drawing of the

wiring harness above. This should leave about 7" of joined pair.

2. Solder the black wires of both black-red pairs through one of the supplied star-

washer lugs. Reserve the second star-washer lug for the ground harness, which is

built next.

3. Twist and tin the ends of the red wires as shown Figure 20, then form then into

hooks.

4. Refer back to Figure 3, to the wire that used to go to the left channel module that

still hangs off the positive terminal of C12. Cut that wire to about a 1" length and

remove all the insulation. Crimp the hooks in the red wires of the harness to the

super heat sinks)
