I don't know how accurate it is or if that amp is grossly underrated (which I doubt) but the 2 Ohm output rating is 450w.im not planning on giving them alot but the subs are rated at 350 rms so i could still blow them at 2ohm
well because from what i heard is that it is way overrated. It is 4000 max. Im not to worried at all about these subs. They were basically given to me.
