with the amp that you have it will do around 1400-1500 rms, i would say you could go with a type r if that was an option, they get really loud off of that amount of power, the T3 subs are nice the customer support sucks if you have a problem, scott and the guys at FI used to work for RE and they have nice speakers, i would go with the BL with amount of power that you have, there are many options out there.
I personally am using a ID Max 10" and it gets really loud and is on the playing field of the JL W7 but doesnt require the same amount of power
