Go with the SDC's either way, if you can fit 2 15"s and make it work than go for it. It would get nice and loud compared to your old system. If you can only fit 12"s stick with the SDC's and it will still be way louder than your old system and sound great. Also those SDC's are underated power wise and can take about 1000 watts so if you have the money get a more powerful amp, something around 2000 watts. Maybe the aq2200d.
