New to the forum, Was looking to see if anyone had much experience with fiddling with the Fox's audio (specifically installing an Apple Carplay double din headunit). I'm not the most experienced with wiring so was wondering if anyone had any advice. With regards to the actual speakers I've read that the rear has the holes for them but none fitted, how should I go about installing some (removing the trim, any adapters, recommended speakers to use) and also looking to replace the front speakers too. I have no clue of the sizes I should be looking for or any adapters that would mean I wouldn't have to fiddle with the wiring too much. Obviously new to all of this so any help would be greatly appreciated.
