The type x's imo are sound quality subs. since u listed ur score i'm assuming that your concerned with that and not so much the quality. I have 2 type r's that I run with a kicker zx 1500 at 1 ohm so im making slightly less power than you and my box is a daily box and needs to be smaller and I do a 144.7 at the headrest. (was ur score at the headrest?) a fellow team member of mine is hitting a 150 in a B2300 with a 15' type r and a kicker zx2500. Another team member of mine had a grand cherokee ( not sure what year ) and had 2 type r's powered by a Viper 2500 and was in the high 146's and low 147's. IMO I believe that if your trying to increase your score then go with type r's. I believe they're louder. If you want sound quality stick with the type x's. You could also stick with the type x's and put a lot more power on them so if you want to try that you can to.
