Does anyone know how to get the rear door speakers to work??

If there is a box under the seat for ICE it's a CD changer, as i said i dont care much about ICE but any ground loop isoator would be connected on the audio output, i didnt dig much but the first i've found on the web has those RCA plugs for that reason https://www.ebay.com/itm/RCA-Audio-...solator-for-Car-and-Home-Stereo-/141609016211 and as your system has the noise only with the parrot and not on it's own something which works on the same principle is needed

Thanks. I have CD changer under driver's seat, but under passenger seat is a metal box:



Interestingly, I contacted JustCarKits.co.uk (who I have used before and had good products from them). I described the problem and they said:

"You would appear to have the Harman Kardon version and will require a different interface:
RAN06PAR

I am not convinced I do have Harmon Kardon system but I could believe it. IF the ONLY way to know, is by the logos on front speakers, then either I do not have HK system, or I do but somneone changed those grills in the past and replaced with ones without the HK logo. I am googling to see how to 100% confirm if I do have HK system. If anyone knows a definitive test, please shout!
