See attached. The highlighted piece of metal is where the RCA center conductor will make contact.

it seems like its .5v ac straight from my phone, and from my deck it was .7v. Will double check that when I get home.

So double checked just now. About the same through the phone, .4-.5v. Through the deck read out about 2.0v this time, both left and right rca ins and consistently.

With that input signal and level, what's the AC voltage across the speaker terminals of each channel with the gain at the max position and the crossover set to full range?

Same results on both left and right input. 0.6v ac with no speaker hooked up. Shows .0 volts with a speaker hooked up.
