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

Do you mean other than the ones that came with it? NOT recommended. But not impossible either. You assume all risk of equipment damage if you proceed.
First, kiss your warranty goodbye.
I'd go with a series connection or you WILL present too low an impedance to the modest amps.
That means + to minus on one speaker, then + of that speaker to - of the next, then + of that speaker back to - on the amp. Repeat for the other channel.
Start with LOW VOLUME and see how the amp reacts. Of course, you'll have no way of controlling individual volumes so if the speakers are mistmatched it won
