I may be putting 6x9 tri's in the rear arm rests. This location may limit the volume if you have rear passengers. Since I rarely have them, I have chosen this location because it's more of an enclosure. It's still in doubt since I'm not going to cut up my originals. I bought a spare pair to cut for the openings... but the seller sold me coupe arm rests. So now I need to find out if they can be altered to fit convertible.
