I got the pioneer Deh-P780Mp, I had it for like 3 weeks it was working great wit my system but outta nowhere my system start to make a constant rumbling sound. Even when i pause the music u still hear constant rumbling. i changed the rcas and it still did the same thing massive rumbling, Anybody have any ideas what it could be, I have a feeling the pre outs in the cd player coulda went bad but im not positive thats why im asking here. Thanks
i heard this happen when some one grounds to there altinator, or when the use a positive off the alt. it will work fine for a while, then 1 day you start hearing noises...
i changed rcas it still rumbles, i also tried my friends amp and as soon as i try to turn the music on his amp goes into saftey mode, it dont wanna play off my head unit.
