Question about Nakamichi PA-504 Car Audio Amplifier
I had my PA-504 hooked up to 4 speakers, one on each channel. One day a passenger told me the speaker next to her wasn't working. I tested it later and found that it was working ... but at a very low volume. When channel 1, 3 and 4 are at normal volume, channel 2 is barely audible. I have checked and re-checked all connections and they all were in order. Does anyone know what this could be? Did I blow channel 2 (even though I NEVER turn it up too loud), and is it fixable? Thanks.
You can check if channel 2 is blown by switching around your RCA plugs. If you are using the speaker wires as high power inputs you can change them. I.E. swap the left channel with the right one. I assume you checked the gain control on the amp. If channel 2 works with channel 3's inputs then its your head unit or the wiring. If you are lazy take the amp to a car audio store and ask them to bench test it for you. Hack
