System trobles I think it wiring?

[hitman34608 10+ year member]

I been getting this weird screeching noise I have no clue if it wiring or what? I started getting this noise week after I got my new radio installed . I have taken it back to shop 4 times they have no clue what it is ? I hate Knoxville there is no audio shops I can trust to do work on my car. I have taken radio out to see if any wires are loose it does not look like any are? So any input would be great!

thanks,

Blake

I would double check that all your grounds are good. It sounds like alt. whine to me.

Is it making that noise with the car both on and off?

Both and just so every one no that video was recorded with the car shut off.

Early morning bump! Also when my first stereo was installed it had these rca splitters and I was wondering if this could affect the new deck at all? Yes I no one unplugged in this picture I was trying to see if could fix this problem.

I suppose those y adapters could have something to do with it...what brand of HU is it...it might be having trouble grounding on the RCA's...pioneers seem to have this issue the most, I didn't believe it when I first read it but after working with them some its a real problem

Its brand new Kenwood Kdc-mp 445U. I going to take it to Best Buy tomorrow see if they can help I no there not best but worth shot . Bump any more recommendation?

Simplify everything to try and isolate the problem, try new rca cables - again one at a time, switch up outputs/inputs, check/re-do all grounds. Bestbuy should swap the deck out no questions asked if you say its bad and have a receipt.

I did not buy deck from Best Buy I got it from Crutchfield . I just had deck replaced by Crutchfield cause one audio shop thought it was bad deck so they sent me brand new deck same problem is happening .
