i personally hate rockford and jl so dont talk tome about them.....but probably just about can give u an impratial opinion (even though id go for the memphis anyway!!!) powerwise the are probbaly gonna give you the same altjough i would trust the memphis to do a better job of stability at 1 ohm. oh and the rockford average price is around $500, memphis a little cheaper, around $420. Id go memphis, but thats only me - rockford are good, make no mistake.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
