Hello all, Would someone kindly give me a little advice. Recently bought a V Reg 18t Quattro sport avant B5 and love it to bits. The previous owner has had the Concert stereo replaced for a aftermarket Alpine single din stereo. Great stereo but everytime i switch it on i get a feedback noise from the rear, even without the stere switched on i still get feedback speaker noise when i start the car. My speaker system is not bose and i do not have the Amp under the changer in the back but there is a sub speaker and i think the rear speakers may be active speakers. Anyway, can anyone advise how to get rid of this noise on start up please. I am upgrading to the Symphony double din shortly as i managed to purchase one at the GTI International Show along with the stand alone Climate Control but now i am having trouble getting the double din cage as they are like Rocking Horse **** to get hold of for the B5. I keep trying Ebay everyweek. Can someone please tell me if i just need the cage or do i need the full console with ashtray etc. Thanks for your help. Rob
