So a constant problem I've been having with my jeep is my radio. It's a pioneer head unit, whenever it's in i get a strange buzzing noise, things that make it better or worse are something like locking/unlocking the doors, turning the head lights on, etc.. It started happening after i replaced my old pioneer unit when it was stolen. Best thing I can think of is some sort of interference or loose wires between the unit and speakers, but I just can't figure it out. Any Ideas? I'm sure this was poorly described, so let me know if you have any additional questions.

 

Check the wiring harness, if still there on the vehicle side. Also check the ground.

 

ground interference

 

it is wired wrong...or bad ground. i would just re-wire it to be safe...

 

I had an issue when I put in my new Alpine deck that when I stepped on the gas all my speakers went fuzzy, I recrimped the power wire and have had no problems since. Maybe double ground yours? Couldn't hurt anything and you'll be sure it's grounded. If that doesn't work i'd try to hook it up again from scratch, sometimes a clean slate can do the trick.

 

i actually figured it out, turns out that when i installed it i never connected the ground wire. the old one had been cut when the deck got stole and i just never payed attention to it.
