Hey, I am thinking about doing some audio work with my new 2000 b5 s4. I would like to keep the stock deck. I have the bose system. What i want to know is how much i can do keeping this stock deck. I would like to put some speakers in..can i just power them with a amp instead? I also have a 12 inch sound splinter sub w. 1000rms AMP. Is their a sub input in the rear of the deck? Thanks guys.

 

JL Audio Cleansweep....

or Alpine has a similar piece

check out JLaudio.com. You can keep the factory deck if you do a Cleansweep, then add anything and get rid of the terrible EQ settings in the factory deck
