does anyone have a diagram of the bose amp for an 01 a6? i am trying to install an aftermarket amp/sub and leave everything else stock (for now). i would like to use the line level converter. i am trying to tap into the rear left +- and rear right +- using wire taps, and convert the speaker wire to the rcas then run to the amp. would you guys wire directly to the speakers or from the bose amp? pics would be great too.

is the bose amp for the a4 1.8 the same in my car.

thanks
