    Sub Power Amp Install


    I'm going to be picking up a 57 plate A6 Avant (C6) soon (non Bose) and want to use my Kenwood mono amp to drive a sub keeping the OEM MMI stereo setup (don't want to change the head unit). Is this possible? Is there a separate RCA pre-out for the existing sub? (I've noticed that there is a sub level control on the MMI)

    If your C6 is anything like my B7 then you can either use a hi-lo converter (tapping into the speaker wires) to convert to an RCA, or the rear channels may already be pre-outs (to the rear amp) and just need tapping into and converting to RCA connectors. Hi-Lo converter is the most fail-safe way, doesn't matter if you have bose or not then, will still give you the volatge RCA output you're after. I did the same for my sub install
