If those are the old sx's they are 1000 watts each, you are running that amp at only 2 ohms. You have more power in that amp if u have good electrical to keep it in the 14v area. But a lot things come in to play.
Hey Steve if you guys need any help moving boxes or tapping, packing, or anything like that just let me know. As long as I am not working that day I would be more then willing to help out for free. I dont think you want to see me topless
