So mainly DCON or SA so far, I looked into the Fi SSD and it takes 800RMS. I don't think the amp will push it well. Is that correct? Also everyone is mainly saying 12", is it going to be a big difference between a single 12 vs 10? Trying to save as much trunk space as possible. Also looks like every one is leaning on the ported side as well. No one here likes the RE's anymore? I remember when all the forums use to be about RE's... How about Skar Audio VVX-12 $169 ( I havent heard much on this sub though) or a Fi X? a 10" in an optimal box will out perform a 12" in a cramped box any day. A 10" driver such as a Dcon in an optimal ported enclosure will sound great on low power. Not much space needed. Since RE started adding "X's" to everything, all their subs have gone People used to talk about them all the time because their old drivers were awesome, and now their new generations are just watered down budget made drivers. As far as the Skars, they are pretty new to the game.. not many people with personal experience. But made around the same people affiliated with SSA (Mark etc...). Fi X would be a nice choice as well for a low price. For low power and space, I'd vote between a 10" Dcon or X in a ported enclosure on about ~300 watts and call it a day.
