Thread: radio interference in one speaker??

Hi
I have really annoying high pitch buzzing noise from front passenger tweeter in the A pillar with radio or CD playing. Noise rises and falls with engine revs, so is likely the alternator?.
I have the harmon kardon set up and checked all connections etc and seem fine. Noise only present in the one speaker - perhaps this is faulty???

Any suggestions ?

Cheers

You could be right, but FWIW...I don't have the Harmon Kardon, but aftermarket Alpine H/U with Alpine Type-R splits replacing whatever the factory junk was.

Sometime after the installation the system developed a buzz from the driver's side split, which like yours rose & fell with rpm. Thing was, some days it wouldn't do it, or at least not straight away...Did my freakin' head in.

I tried all sorts of things, took the panel off checked the connections - all ok, checked the harness to cone in the door, all good.

Eventually went back to installer. They were also bemused and after a bit trial and error, out came the head unit. In the end, as you know there's not a lot of room behind the head unit in the D2 and where the connectors from the head unit join the Disco harness one connector was getting pressed up against a piece of dash frame causing the interference.

So if you haven't already, check & double or triple wrap the connectors from the H/U...just in case. So simple, so frustrating - good luck!
