HELP!!!! 2004 Audi A6 S-LINE Aftermarket Headunit (SingleDin)
 

Hey,

I just purchased a 2004 Audi A6 S-Line and I want to desperately upgrade to a SingleDin Pioneer or Alpine headunit. Can anyone suggest the perferct dash kit, wiring harness, and also, the antenna adapters that would be suitable for my project, and also suitable for a later upgrade which will include 2 JL Audio W6's, 2 JL Audio HD1200/1 amps.

Thanks for your time and advice!!!!
