its a bad RCA ground in the HU. simple fix is take about 7-8 inches of wire and ground it. then strip it back far enough to let the rca slide over it... very simple and works.... there are places on the back of the radio u can use for a chaisis ground.

ok nice ill try this!

clean your battery terminals. if there is any corrosion that can definately cause engine noise.

i never do the rca trick described previously.

try a new ground, dont share your ground with any other equipment.

run your rcas and power wires on opposite sides of the car.

most likely if you still have noise after all these fixes, it is going to be your equipment is faulty. decks and amps have built in noise filters, some older amps dont have them, others have shitty ones... others have just gone bad.

is your equipment used or brand new?

its the head unit, i have 4 pioneer deh 7500s that require the same rca grounding. as stated it was a problem in all of pioneers decks at that time. Internal fusing on thier noise filter popped and creates the issue your experiencing.

The person who installed the head unit that was in the car when I bought it used the park light circuit for power. I had to turn out my park lights to listen to music, and it also presented alternator whine, though I seriously doubt that is the cause of your problem, haha.

That sure was a mess for me to fix though. They cut off the factory harness and got all the speaker wires mixed up. I had to run a new power wire from the fusebox because the original power wire was no where to be found.
