Ok here's the problem we weren't getting any sound out of any of the in-car speakers but the subs are working, that's the first problem. We weren't sure what was going on, so we started switching the RCA's around in the crossover, but nothing changed, so we're still stuck there. The second problem is, as we were messing with the RCA's, at one point we touched one of the RCA's to another one and heard some popping noises and everything shut off. All the fuses on the amps are fine and the fuses for the vehicle are fine, we took the deck out and the fuse on that was blown, it's a 10 amp fuse, so we replaced it and everytime we put a new one in and plug everything back in the fuse blows again. I apologize for this being kinda long, and rambling, but we're not sure what to do, please help if you can, thanks.
