can i use the audi 6 disc cd changer with a aftermarket deck? i like the tape deck with the cd in the trunk but im looking for a little more. the bose speakers sound really nice too. also is the size limited to e or can i go double din?

thanks

1999.5 audi a4 quattro 5 speed

 

If you replace the trim and make a few modifications you could go double din.

 

will that work with the stock six disc cd changer in the trunk? or does it all need to be audi components?
