- Confirm that all terminal strip connections are firmly connected.
- Check in-line and built-in fuses. Both +12V and RMT terminals must have +12V to chassis ground.
- 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 card to LEFT& RIGHT low-level inputs of Amplifier only ( Do not connect the other end of the patch card).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.
