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!
