Hey MB World.. just got myself a clean little 500 and it came with the custom box aftermarket sub but stock amp.. my cd changer was a bit chewed up so i replaced it and the sound stopped working. i looked further into that corner there and dont know what kind of hack job they got going on in there.. question.. when you turn the command on there is one Fiber line that blinks 3 times.. does that go first to the changer or the amp? it was all working great til i disturbed the wires so i am just a bit lost :? any help will be appreciated
