[QUOTE="brandonio21, post: 8257008, member: 660866"] Hi all, I have a Sony xplod 1000W 2 channel amp, and it has worked perfectly fine with my 2 kicker 15 comp subs for almost 2 years. Last week, my alternator died, and so I replaced it and purchased a new and bigger battery for my car. However since this happened, my subs would randomly cut out, so I bought new wires and a new RCA cable and replaced everything. They still cut out and now they wont even hit, at all. I don't know whats wrong. I checked the voltage at the battery with the car on and off, and its good both ways. I also checked all my fuses for resistance and continuity, and they are all good. I then went to check the voltage going to the amp to see if it was just underpowering the subs now, and low and behold the voltage read around 5.4 volts. This was weird so i took the wires out of the amp and tested them and they tested good at 12.2 volts. Does anyone know why my voltage is dropping. It only happens when I screw the wires into the terminals on the amp. The inline fuses on the 4 gauge power wire are also ok. I checked them as well. Any help would be GREATLY appreciated!!!!
