hi guys

ive just replaced my standard audi a3 head unit with a sony one but the rear speakers are not wired up. im ont sure which ones are the speaker cables. there are about 3 or 4 blocks not used but some are for the cd changer in the boot. Also does anyone no how to get the speaker front off so i can replace the speakers? ive used screwdrivers but no luck!!
thanks

 

I still have the same problem. See my post in this forum, a couple of weeks ago : https://www.audiforums.com/m_65422/tm.htm it seems that we have to use a couple of wires which are going to an amplifier somewhere in the car. I found which wires to use (see my topic) but ca't get it to work [:@]

 

Just wondering...i had same problem in my A3, i have the 96 model, with an onboard sub,

on your old set there should be some sort of wiring guide on it. I found it on mine but realised the Goodmans HU i bought didnt have the phono inputs on it so i couldnt connect rear speakers or the sub. However got fronts working and they sounded ok. But decided just to return the Head Unit and get a refund, will have to look into getting a decent head unit for my newly purchased A3



Any one know of any cheap GOOD head units made by Audi, that dont require facias?

Thanks

 

Has anyone found a solution to this problem yet ? ive got the same problem where i have the front speakers working but no rear, ive tried 2 different smart leads that change the audi wiring for the speakers but neither worked, so am stook with front only and hardly and bass.

 

I've heard about a lot of people having the exact same problems. I've kept the BOSE concert system just because it sounds like SUCH an **** to change it all, even though the rear speakers are pants! Anyway, I think its something to do with the line out setup of the Concert system. Not a man of electrical persuasion so don't really know too much about it! This is the closest thread I could find relating to it, hope it helps...
