TROUBLESHOOTING
SPECIFICATIONS
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.
(or signal source)
(right to left or
vice versa).
b. Check“BALANCE”control on Car Stereo
to verify it is at mid-point.
c. If using RCA Low-Level inputs, reverses the input plugs at the Amplifier
(EQ, X-over, or other signal source) or connecting cable.
If the channel that is silent reverses position, the problem is in the Car Stereo
