    the amp spec you quoted means that "IF" your speaker load is 4ohms the amp "could" output 1600w. you DO NOT have to have a load of 4 ohms to bridge the amp, you can run an 8ohm cab OR two 8ohm cabs that would equal 4ohms. you can even use just one 4ohm cab, but if you add another 4ohm cab you load drops to 2 ohms which is low for almost any amp. stewarts as far as I know are designed to shut down when the load drops below 2ohms. as far as I understand the load an amp "sees" while music is being amplified fluctuates and I suppose can go higher than the starting load of say 4ohms and go lower, but I'm not sure how much lower.

    I have a stewart 1.2 and I ran three 8ohm cabs at moderate volume for a couple of hours and my amp did not shut down. the load was 2.6ohms starting.
