I am using the Sunfire 300/2 which supposedly has 600 watts at 4OHMS. They really pound out more bass at higher volumes than the HK Sig 2.1 that was hooked up before(which only puts out about 200 at 4 OHMS). A very good 5 channel amp for the money too...

Go for the Sunfire 600/2 which supposedly puts out 1200 watts at 4ohms, that will cure upgraditis...maybe not tennitis though.

M80ti's, VP150, QS8's
