Up until now, I've been using a 10 inch JL shallow sub in a sealed enclosure. Although adequate, I've never been completely happy with the implementation. Leaving the sub in the trunk is ineffective, so it sat on top of the rear cubbies firing upward, looking more like an afterthought. Top up / windows up it sounds great, but didn't overcome the road noise very well with the top down. My solution - a forward firing sub integrated into the space occupied by the rear seatbacks.
My first experiment used a pair of CDT 6.5 inch dual voice coil (DVC) drivers, rated at 42hz to 4khz free air - no enclosure necessary. I like the DVC because wiring options let you configure a pair from 2 to 8 ohms. At modest volume these sounded great, but lacked the sensitivity to drive them hard at 100hz to get on top of the road noise. I'm happy with the response of these drivers in the mid-bass, so the plan is to move them into the doors eventually.
In the 'final' iteration, I went with a pair of 8 inch DVC subs, rated at 10hz to 400hz. The drivers are loaded into a ported/tuned 2 chamber mdf enclosure with a fiberglass front panel.
