I am in the process of mounting to 10 in the rear floor and I think it will turn out good the sound of subs carrys a lot so I don't think them being back there will matter much. As for the carpet the sides come off real easy all u need to do is take out those pop rivets and they pull right off. The carpet on the trunk u just need the to unscrew the two little plastic pieces that look like hangers and it comes right down also.
