Are you looking for mid suggestions? Kinda tough to tell from the video but your doors look similar to my 01 Malibu doors. I had 4x6's in the fronts, and its kinda tough to fit much else in there, so I I'm in the process of building the doors out with 8" Silver Flutes ported. I'm halfway done and this is easily the best mid setup I've ever had.
Even 2x 6.5's would be nice...
