I know there are loads of posts about similar problems on here but I can't decide what exactly I would need to do for my set-up, sorry!
So my position:
I've recently bought an 52 plate S3 and the previous owner swapped the originial Audi tape head unit for a Kenwood one. Details below...
Previously - Chorus II A3 tape player
Now - Kenwood KDC 237 cd with aux input
Also, theres the same standard kit in the back as before, so no change to amp/sub. Not sure what it is but theres a box in the left hand compartment (nothing in the right one), think thats the sub? Don't think its the Bose set-up (ie speakers don't show the bose symbol, etc).
Theres a strange buzzing noise that comes from the rear speakers, it doesn't get louder or quieter when the vol is turned up or down just a constant buzz. Its not very loud but is starting to get pretty irratating on longer journeys.
Any ideas on what it is and how to fix it? Simple instructions would be handy as i'm rubbish at electrics.
Cheers in advance.
