Looks like they are too me, at least the ones on their website. Just buy my amp(i would dump the jensen and legacy stuff man //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif, no offense intended) in my sig and hook it up to 2 12 prs and you're set. Not trying to just make a sale either, it's a hell of a price that cant be beat. If ya wanna go even cheaper there a ton of high quality used amps around that do 500-600 watts at 4 ohms and 1 ohm bridged.
