works flawless awesome amp. i bought in in november 07 so it has bout 1 yr and 8mo ive used it a 2 ohm, 1 ohm and .35 ohms and it really comes to life at .35 haha but yeah its not recomended for it to be used with music, althoug i did play music sometimes and could do 139.9 on bassrace with the nissan quest with a single 15 but yeah overall its a great amp.
