The DC sub is of different intentions and a 3" coil driver. Might want to clearly define your goals and needs to help narrow down the search and not take into consideration random suggestions.

I am looking for the loudest lowest playing setup within the space I have available, I have about 1.36 per sub with displacement under my back seat, I have 2100 @ 1 ohm and I listen to mostly reap and r&b if this helps narrow done my choice, like I stated before I am trying to find a setup that I wont have to replace anytime soon!!!
