So I came across a Mitsubishi da-c20 preamp and a Mitsubishi da a10dc amp everything powers up havent fully hooked it up or anything but all lights come on and i hooked up I a speaker and when I touch the RCA connector it makes its sound then I disconnected from lack of knowledge lol. Dunno how to post pics I know I have enough posts but haven't been on in a bit and can't remember what to do.
