ok ive run all of re subs at 1 time or another,except the mx.i put 2 15'' sr's in and they sound really impressive,ive been running 2 15'' sx's,and them sr's almost keep up with my sx's,the sr's have better lows and sq,but they still impress the meter pretty good also,and the power handling says 350 watts rms,ive run them on my 2500d,and my powerbass 1500d,no problems,not even a smell of the coils,all in all i say if u want a very good sub that doesnt cost a arm and a leg,try em out there tough,im very pleased with them
