Ok, I installed my new DC xl 12, plug my amp back in and got almost no sound from the sub, just some wierd noises. So with the music still playin, I figure i'll switch the RCA's. When I unplug the first one, boom, the sub starts bangin. First question, how could one rca work and both make it quiet? 2nd question, i'm only getting a 2-4 volt reading on my dmm at the speaker output, why is this? The shit is loud with one rca, but sounds lacking, i need help to figure this out.
EDIT: I should add that I sold the rf processor and am using a high-end signal converter made by Helix(german).
