    dual PC925 installation

    right side, under the Bose subwoofer:


    left side, with the rack removed:


    The left side is not perfectly flat, as I just shoved it into the styrofoam. a bit of trimming will sort that (as I did on the left), but the battery is really wedged into that pocket.

    Each battery has its own ground, and the positive terminals are linked. the 4 gauge cable was spliced into the stock positive wire, and then run behind the panel. The positive cable to the second battery runs under a trim piece to the other side.

    All that's left is to get a body shop to finish removing the battery plate, then a new piece of carpet; I unbolted all the attached hardware. I can reuse the cargo tie-down however - I found that hidden under the plate, the floor is drilled and tapped for the tiedown D-ring, just as it is on the left side.

    So this is IMHO the best way to get rid of the battery box and still optionally keep the spare, plus the toolkit and CD changer (if you have it). I just didn't bother reinstalling the rack, and I took out the spare and now that area is a storage bin, with detailing stuff, microfiber rags, factory air compressor, toolkit, and my torque wrench.

    I'm very pleased with how it worked out, and how the PC925s just popped right into the side compartments.

    Nice Idea...Why did't Audi think of that? LOL....

    The spare well is still messed up with those three bolts coming through which does not allow a normal spare to fit in..

    Cool. Geez those things are little. Is there a bigger one that would still fit in the passenger side well and have enough CCA's ?

    Nice work! You can always surf eBay for the euro carpet and tie-down clip.
