My guess is a ground loop isolator or engine noise suppressor of some sort.
I have taken my HU out a few times for RCAs etc... but I was not the one that installed it so when I this thing the first few times I didnt give it much thought or care, it sounded fine and thats all that I cared about. Now I want to reground my HU and this is in my way. It is t-tapped into the ground (black wire) and is wired in line with the constant 12v (red and green wires)
Any ideas?
thanks
