yeah so i had the stock set up until my volume button broke off the top part with the tape deck on it, and i would have cost like 400 dollars from ford to get it replaced. so i had best buy install a new unit with a flip down screen. it is working good but the problem is that the balance is messed up. when i fade to just my front speakers and switch from left to right, the right sounds great but the right sounds like there is almost nothing there. when i do that to the back both sides sound great. i know that the speakers arnt blown cause i switch the left to right on all the speakers and the problem still happend, and same with the amps. i know the left amp controls the front and the right controls the back. so i am thinking it has to be something that is inbetween the amp for the fronts, and the fronts themself. any one else have this problem or know how to fix it!?!? if not, does anyone have an aftmke head unit that works great and what kinda is it!?!?!?
