JVC head unit alternator noise trouble

[xclusivecar]

OK--

Replaced the becker with a JVC HD radio receiver. Bought thru Crutchfield using their wiring harness and PAC oem-2 adapter to retain the oem amp and speakers. Install went fairly well with the exception that I now have the dreaded high pitch whirring noise in all speakers. This sound is RPM dependant. After checking all grounds and re-grounding the noise still exists. After a call to Crutchfield and the service tech making me splice/re-splice different wires he determined it was a power issue and not a grounding issue. I was told there was nothing I could do to get rid of the whirring noise.

Anyone who has replaced their receiver had this problem and had a solution??? I guess I would try to splice in one of those noise cancellation devices..but this seems more like a band-aid than a fix.

Sorry so long...BTW--I LOVE the HD signal in Chicago!!!

Thanks!

Your problem is a common one. Anytime you replace a headunit in a car and use an adampter to plug into the existing OEM amp, you get alternator whine. I'm not an installer, but every installer I spoke to (5), said the same thing. You must also replace the amp or you will get alternator whine.

In the past, when I've replaced head unit's myself, I got alternator whine.

I know it's expensive, but put back the Becker, return the new head unit to Crutchfield and have a professional install a new head unit & amp. At least this way, you don't pay him/her until the sound is clean.

Good Luck

WE UNDERSTAND!!!! YOUR A DICK...OK...WE KNOW YOU DON'T LIKE ME, BECAUSE ??? i bashed your painted tail lights,,,,lets be civil......you dont have to reply that im a loser and im no help...what does your reply say in helping this guy,nothing!!!!...i have no problem with you,just the **************** job you did and the safty issue. get over it and lets help this guy out

When I say your a loser, I am not implying anything other than what you said in this thread. What I said was that I did the same thing as him except I have a different year car and that its not normal if his car does it. I don't care about the lights, so what? I think your some 13 year old kid who can't even drive and wants to annoy people because you have a bad life. You certainly seem to have the grammar and education of a 13 year old. Why are you even on the forum if you "have already done everything" (including your list of "mods" and stereo stuff), won't help anyone, or post anything original? You need an attitude adjustment that your father never gave you. Why don't you try and figure out your problems instead of being unhelpful and a burden on this forum.
