Simmer down, Bro. What you need to understand is at some point your amp will have to draw all it's power through the cigarette lighter wire. And trust me the wire behind the plug is smaller gauge than that cord coming out. As your batteries run down you are actually running the amp on a piece of 18 gauge wire behind the dash. STOP THIS! The only reason this has worked so far is because your batteries are sort of acting like a buffer on the amp draw. As soon as the current demand exceeds what the batts have left, that little wire has to take up the slack in supplying the juice. IT CAN NOT DO THIS! IF THE FUSE DON"T POP THE WIRE WILL BURN!!! GO TO WALMART OR WHEREVER AND GET PROPER WIRE!!!!!!!! Make 2 runs, one for pos and one for neg from your battery. That way you dont have to modify anything at all and your good to go.
