I got the fuse replaced and the entire system souned like it was lacking power, the sound was washed out, tinny, almost no bass (even with 2 12s). I thought maybe i had damaged the amp, so to make sure it wasn't the headunit I played a song from my phone to the amp RCAs. Perfectly fine.

I think I may have messed up the speaker signals when i was fumbling around with the amp. I need to go buy some butt crimps and ill redo it all. Right now the wires are twisted and hotglued.

Could a lack of ground make speakers sound trashy?
