Whats not to say about this sub, its amazing i bought this like a week ago with the intentions of this sub blowing everything else outta the water and it did i have no competition with this sub. I figured i would have competition with my friends 12" jlw3s but i soon realized jl is not the best thing ever made and that the name was bigger than the sound by far the best subs ive had. I also have a hifonics hfi 1500 watt amp runnin at 2 ohms.
