Hi guys,
I've had my F90BT installed for a while, but I decided to do the hardware bypass. relocated the mute wire correctly, then grounded it. Grounded the parking break, did it all.
my problem is now my subs as soon as my deck turns on start to just rumble, even with the volume at 0... i try and change it to hd radio or ipod, cd, everything, but when volume is at 0 the subs still rumble and make bass.
why is this? didnt do it before the bypass, everything worked great, but now regardless of what it is, when volume is at 0 the subs/bass still rumble.
any idea why? or has this
