The Bose Andy Mac Sub on 2005 A3 Sportback? Speaker recommendations?

Hi there Ash..

I contacted Andy about this a while ago and unfortunately his subs dont fit in the sportback. Apparently to make more room in the boot (probably for the tech spec sheet) they have put a weird scoop in the side panel. I only really noticed it after Andy pointed it out to me... anyway this makes the sub a strange shape and difficult to replace.

I have a 2005 / 06 Sportback and am looking to replace the sub and Speakers after installing an Alpine system and Bluetooth module. I'm not 100% sure about mounts etc for the doors but I think a 6.5 inch component speaker will fit... have no idea about rear doors, so I'd like some info here and on the sub front Im thinking about a slimline Pioneer one Ive seen that sits across the boot florr, you can even put luggage on it! got to be better than the stick tupperware crap
