So I just hooked up my pioneer deck, hifonics amp, and kenwood 12" sub. My friend did the wiring harness on the deck as I wired everything to the back of the car and battery.
Everything sounds good when the engine isn't on but as soon as you turn the car on a high pitch whining sound comes from the speakers and as the rpms go up, so does the sound
I can pretty much tell people i have a kenny bell.
My friend said it was caused by the remote/power wire being with the speaker wires but I rewired so everything was separate and nothing. What could be causing this? Is it alternator whine?
