Rear speakers are buzzing/humming
They do not increase with rpms, changing the input or volume..
If I have the car on the rear speakers will hum or buzz in a way. But if I turn the car off and turn the ignition to acc it goes away. Could this be the rcas to the "rear" ? I'm using a old pioneer deh p2900mp at least 15 years old but it still does what I want it to. It only has 2 pre outputs. Front and rear with the rear as a switchable sub output. I have y splitters from the front pre outs giving me 2 rcas for a 4 channel amp but the fear speakers are the only ones that are humming or buzzing. My ground to the 4channel amp is bare metal under my seat. Is it possible I have created a ground loop ? Or does that not makes sense that it only does it when the car is running.
