im about to be a new owner of an 09 S and the first thing Im going to do is change up the audio, and my question is what is the most popular way of adding a 4ch amp... the basic SNI, cleansweep, high level in, is there a full range output from the non hifi system, im going to be running 2 pairs of 130v2 focals and an fp4.75 and would like some input from other owners

thanks from a newbe and first time poster

Go over to the NAV & Audio section. there is lots and lots of info on this subject over there.

Also one thing to remember is. If you have the HiFi system the OEM amp must stay in the car so that the dealer can perform service on the computer system if needed. If the amp is removed they will not be able to work on computer related service which is just about everything.

Also of note is that the standard system has a roll off of -12bd below 100 hz on the rear channels. Front channels are about -3db as 20hz and -.5 db at 30hz so that is the set of channels to use to drive a sub.
