islandpride684 Posted August 25, 2016 Report Share Posted August 25, 2016 Ok so I'm out here and it is making noise with the engine off and stereo on, a hum noise and if I shut door or anything it makes noises Shoot a video real quick of what it sounds like, also just cut the black (ground) wire from harness, connect a ring terminal at the end (connect to wire coming from headunit) and find a good metal contact behind the headunit and ground it there...is there noise when the rcas are unplugged from the amp?

welderblake21 Posted August 25, 2016 Author Report Share Posted August 25, 2016 It makes no noise if unplugged from the amp. Ground to amp is good, all connections to amp are good. Seems like the rcas are the problem but idk how they could be they worked fine not long ago. Link to comment Share on other sites More sharing options...

welderblake21 Posted August 26, 2016 Author Report Share Posted August 26, 2016 If I unhook the rcas from the amp it still has engine noise but it's not as bad. I think it's the amp, because I've not had this problem until I put this amp in Link to comment Share on other sites More sharing options...
