i bought alpine-9847, and it makes werid noise, like would play an old tape. i reground my HU, then checked all connections(all were tightly connected, some weren't so i fixed them), everything looked like it was working as it should, but the noise still comes. what can i do about it? is there HU issue? can it be caused by wire distortion? plz help

does the noise come from inside the head unit or from the speakers?

Sounds like you have a problem with the HU.

Especially if you have redone the wiring and regrounded it...
