Car amplifier troubleshooting

No output:

  • 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.

Tempeture hand on gauge rises and falls as you accelerate and slow down. Also rises and falls when you turn on the internal blower in the car. The engine does not appear to be overheating.

The problem you describe is likely being caused by the dashboard earth (ground) reference moving as the 12v power system current draw changes.

Ensure battery terminal post connections are in good order, clean and firmly connected,
Ensure the all chassis, alternator, engine and dashboard ground connections are intact and in good order.
Ensure all dashboard loom connections are properly connected,
Check alternator output voltage (battery terminal voltage) is approx 14.5 volts with engine running, while loaded with headlights or blower motor running.

If all above is ok, the dashboard internal voltage regulator supplying the instruments may be faulty (unlikely - do all other checks first).
