OK, I have 2 8's under the rear bench with aftermarket AMP using RCA inputs from H/U. My AMP crapped out and my brother gave me a "factory" AMP that hes wasn't using. Anyway, my question is: can I get RCS pigtails and wire them to the Audio inputs of the AMP or are the speaker level power inputs? Power/Groung/Remote are easy enuff, but am a little lost when wiring audio inputs, any help would be greatly appriciated.
