im thining of having the crossover under the front seats, and runnong the wires for the mid and tweeter throu into the door.
Mate, depending on the size of your crossover, you can easily velcro it on inside your door card, i've just replaced mine not long ago, got components in the front door and a set of 6.5" infinitys in the rear door and there is less room in the front than the back door!
Like most people have said, its best to make your own speaker adaptor rings out of mdf, its a bit of a squeeze getting the front door cards back on but it does sound a lot lot better:icon_thumright:
My speakers are all wired direct to a pioneer head unit with 'proper' thick speaker cable and i've also left additional wiring in place for when i install my own stealth sub and amp, so i can run the whole caboodle off the amp(s).
Wiring to the rear door panels isn't too hard, the biggest pain is removing the b-pillar trim to get to the grommets to feed the cable into the doors,just be careful when removing as it just needs prising off very carefully, just lift one side of the trim gently until it 'frees' then carefully do the other side then it should just pop off.
Saying that mines a facelift b5, so not sure if the trim pieces in yours are just screwed on or not... good luck.
