I have 2 of these subs in the atrend dual 12 ported flat pack, and these things are absolutly crazy. i have them runnin off a Sony XS-GTX1852, 100 watt sony amp, at 370 WRMS to both sub and my gains not even half way up and ve already been pulled over, broken my winsheild and rattled my rear veiw right off. now i do not know exactly how much these were brand new, cause i bout mine $50 bucks each from a friend and tey were BRAND NEW IN THE BOX, he had never even opened em, before i got em i was gonna save up and get the 13.5 Dual 1.5 ohm W7,im so glad i didnt waste all my money on those, these subs out perform W7's and Type R's all day long. and i know i dont have the best amp ever, but regardless,these subs slam.

These subs rule, i had 2 of them in a ported box that a 5-Time Iasca & Usac World Champion built, with a Planet 4000D amp, wired to run 1125 Watts RMS per sub. these things hit so hard that I have been sued twice, my car virtually fell apart and i now hear a constant ringing in my ears. Lasted for 3 years before they gave up, and absolutely pounded the whole time, were talking bout cant drive and bump at the same time loud. Definetely anexcellent sub for anyone serious about their bass, and you can laugh at the clowns that paid JL an extra $500 per sub. With the correct ported box, a good quality high power amp or two, and correct subsonic filter frequency these subs will last and give you a sound that nobody forgets.

Running this sub in my car for 3 years with 900watts from an eD 9.1 amp in a ported AudioEnhancers enclosure.. I love it,great SQL durable as hell.gets low and loud and its still in my car now. I beat the snots out of this sub and it never fails me,even when playing heavy bass Rap music The guy who blew his pair in 2 weeks should learn to operate an amp...
