edit id look in to the IA death pentlys ther around 500 or so a sub and they got them in 12's to 21's
21in warden by incriminator audio there 2500rms 5k max but there so under ratted ive seen them with over 4k on them and there not even moving and sundown 4500 when they come out or you could get one of incriminator audio 40.1 there like 4k idk on the price tho
incrimator audio 187 series ,Lethal Injection Series,or the Flatlyne Series there msrp prices are on there web site but if you email them they will tell you the actual price of them
