any advice on the buzzing? note i did have to ground the HU to the rcas behind the dash to get rid of alt noise using gmos 04. i hate the gmos 04 had a lot of problems with it. Ive read a ton on this issue and it always leads to grounds but i have been through that already. My system was buz free but after the rear speaker install the buzz is back. I wanna try some stuff before bringing it back possibly ground loop isolator.
some info: i grounded the rcas from my subbs at the HU to the HU itself and that helped (im talking about a year ago) that is all i did. After this i then turned down the potentiometer down in the gmos 04 adapter and that got rid of the rest of whine/buzzing.
fast forward i get new rears installed and buz is back!
