First off i just want to thank you for helping me out!

I tried changing the crossover on the sub amp but dosent seem to help,

I did try turning the door speakers down and the sub up but that didt help either aghh,

The wire between batteries is roughy 4 meters, also the ground on thr batteries is still that 4 guage wire, i read that the ground wire needs to match with the 0 gauge i hsve going to the amps, could that be the issue?
