Hi Guys, As the snow is falling and my diffs sound "weird" in the snow when the car's sliding, i've decided to sit on the icy cool leather for a few hours and fit my newly delivered stereo at the weekend. Car is a 1999 S3, non-Bose system with the 6 disc changer in the back. I have bought one of these - http://www.amazon.co.uk/KENWOOD-KDC...5ALU/ref=sr_1_2?ie=UTF8&qid=1358535087&sr=8-2 and also one of these - T1 Audio Audi A3 Facia Pack - Audi A3 2000 - 2003: Amazon.co.uk: Electronics Is this all I need to connect the stereo to the car and make it "work"? I'll also be plugging my iPod to the H/U via the glovebox (Dremmel at the ready). I have read there is an issue when fitting aftermarket H/Us to my car as the rear speakers are amplified via a rear amp and the fronts by the H/U, is this correct? If so how do I get them all to fire from the H/U? All responses greatly received.
