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. The maximum

harness resistance between the unit and each speaker should be < .25 ohm. Harness

resistance can be measured by:



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.

Avoid parallel runs or installation of audio signal cables in close proximity of transmitter

coax cables, high current DC power wiring, AC power wiring, or other high current

wiring.

Avoid installation in close proximity to any device with a strong alternating magnetic field

such as an inverter or electrical motor.

Wire size, type, and installation should comply with all industry regulations pertaining to

the actual installation.
