    jady, if i were to run this into an 18 and 410 set of eden cabs, would i have ample power? I really don't know enough about running stereo or bridged. I feel like this is a great deal on reliable power.

    Oh yea. If they are both 8ohm cabs you will get 1000W or if they are both 4ohm you will get 435 into each. This amp has pushed plenty of air. I used to run a Aggie 2x10 and a 1x15 and never had my preamp past 12 oclock. With my El Whappo I never had it past 10 or 11.
