I put rockford fosgate primes in the front side doors. I think the factory speakers were better! Primes pretty much suck. Its a ton of work the way they have them mounted also! I believe I ended up cutting a hole in the door grill and mounting the aftermarket rockford grille to the door, I might have even mounted the speaker to the door with the grille. I'd have to check. I don't remember the specifics anymore but I remember it was way more trouble than it was worth. I dont even remember feeling like the sound was any better either. I plan on buying kickers for the front soon so I can let you know then and post pics if you want.
I also cut out the back dash for 6x9s not sure that was worth it either. I was hoping for more of the bass of an 8" speaker. Looking into adding a slim subwoofer to the trunk soon, or molding 12" to the corners in the trunk (sedan)
