I've been considering upgrading my non-Bose B7 A4 Avant, want to stick with the stock head unit (my local specialist just couldn't understand the desire to keep the stock look).
So I'm thinking I 'just' need to:
Run power from the battery through the ecu box to the boot.
Run a front pre-out from the head unit to the boot.
Run a pair of speaker wires back to the head unit to splice onto the feeds to the front door speakers (avoiding messing with running wires through to the doors)
Replace speakers in all the doors (cannibalise or buy speaker rings)
Find a sub, I'd like to build it into the rear near side boot side panel, looks like that will be a DIY project as I can't find any premade like there are for the A3.
Find head unit wiring adapters to give access to the pre-outs and speakers without interfering with the cd changer in the glove box.
Will the stock speaker wiring be good enough to run upgraded speakers from a decent amp?
Any recommendations on speakers?
Anyone already done an mdf enclosure and still got the plans?
All pointers gratefully accepted
