Wiring Requirements
Loudspeaker wiring should use twisted pair or twisted shielded pair wire. If twisted
shielded pair is used, the shield should be grounded at the amplifier end only.
Speaker wires that are too small will attenuate the signal to the speakers. Loudspeaker
wires must be sufficient so that the maximum harness resistance between the unit and
each speaker should be < .25 ohm. Harness resistance can be measured by:
2.3.2.1 Procedure
Remove the 8 screws located on the two sides (4 on each side) of the enclosure
as shown below.
Install brackets (2 on each side) using the screws that were just removed. Align
all brackets with the open end of the mounting brackets facing the shallow end of
the enclosure as shown above using a #2 Philips screw bit.
Tighten all 8 screws to 12 inch-lbs of torque.
Disconnect the amplifier and speaker.
Short the harness pins together at the speaker end.
Measure resistance across the speaker output pins at the amplifier end of the
harness.
