So I got a store to install my JVC AVX846 double din deck, and I noticed that no matter what kind of source I use to play music, the music would randomly skip from time to time. (bluetooth does it the most, radio does it too, haven't tried CD yet)

By skip, I mean it would do one of the following at random times:

- slurred words (for example, makes eminem sound like has a lisp.. lol)
- sound goes silent for 1/2 a second

And it also has a light buzzing sound when volume is at 0, is that normal? I don't remember if it was like that stock?

Any help would be appreciated!

 

Sounds like a bad HU to me. Maybe the bose amp going out if you're running through it.

 

How can i tell which one is the problem?

I am running through the bose amp.

Could it be the wiring harness' fault? - the store didn't tell me which one he used, and I heard that the wiring harness could affect the sound quality?
