TROUBLESHOOTING

Before removing your Amplifier, refer to list below and follow suggested procedure.
Speakers and their wires should be tested first.
No Output:
a. Confirm that all terminal strip connections are firmly connected.
b. Check in-line and built-in fuses. Both "+12V" and "RMT" terminals must have
+12 Volts to chassis ground.
c. Confirm that signal source( Car Radio/Deck, EQ, X-over etc ) is connected and is
supplying output signal.
To confirm that Amplifier is working, connect an RCA patch cord to LEFT & RIGHT
low-Level inputs of Amplifier only( Do not connect the other end of the patch cord
Briefly tap the center pin of each( disconnected ) RCA plug on the
other( disconnected ) end with your finger. This should produce a noise( feedback
in the speakers.
Only One Channel works:
a. Confirm that speaker terminal strip connections are firmly connected.
b. Check"BALANCE"control on Car Stereo
c. If using RCA Low-Level inputs, reverses the input plugs at the Amplifier
vice versa).
If the channel that is silent reverses position, the problem is in the Car Stereo
(EQ, X-over, or other signal source) or connecting cable.
