I have an 02 a6 2.7t with the BOSE Audi symphony sound system, and was wondering if the BOSE head unit had rca outs so I could put a sub in there?

 

it may already have a sub unit. usually the bose systems include a sub.

 

no. You can do one of two things:

1) add an RCA converter (Blaupunkt part) that would connect behind they Sym II headunit...but that would bypass your existing Bose amp...and require you to run a dedicated aftermarket amp for all of the speakers. Not recommended...based on your objective.

see my pix below for pix of some of these devices.

2) add a line-out converter that would tap into the rear left/right channels near the bose amp. You wan to keep the aftermarket sub/amp restricted to the rear channels (for front/rear fade purposes). For this, I would consult your local stereo shop....or autotoys.com for some ideas of products.

Also, I would join audiworld.com and ask this question on the audio forum (remember to search the forum first).


Good luck!
