i just picked up a set of 5"x7" Alpine TypeS's for $90, and i need to know how to remove and reinstall the door panels. its on a 1989 Xlt bronco w/power windows
I believe all bronco's came with 5.25 or 5.5 in front and 5x8 in rear. That's what was in my 80,89,93,96Shallow 6.5" or 5.25" are the fronts (at least on my 86). When I installed my Alpine 6.5" components the spiders were too big so I had to jigsaw the hole bigger and drill new holes. You can probably make it work if you want to cut the doors some. There's plenty of room back there I think.
Again, I had to cut the rear mounting brackets a little and make an adapter to install 6x9's. The originals are something weird like 5x8 or something I'd never heard of like that. Granted that's my 86. Maybe 89's are different.
