i have seen alot of people going with the type rs they are nice subs for the money but deff no the best and you want true clean power from an amp not some crap that says it produces 2000w, makes a huge difference. i am currently running two type r 12s in a ported box rms 750 to each they pound but my next step is going to be jl 13.5w6 on a jl 750/1 should be awesome
