    Lets say you have a 4 ohm cab and a 8 ohm cab. If you bridge both power amp sections is it going to hurt the power amp? Basically, is it okay to run a power amp at less than 4 ohms?

    4 ohm and a 8 ohm =2.6 ohm . what kind of amp do you have ? most amps wont handle that load. on the back of the amp it will tell you minimum ohm load, most wont drop past 4 ohm, SWR 350 will drop to 2 ohm 750 will drop to 2,6 ohm Ampeg has a load switch on the tube amps .BUT CHECK or you will cause damage to the amp ! good luck,

    I've never heard of a power amp for bass that can handle less than 4 ohms bridged. Lots of power amps nowadays can go down to 2 ohms per channel, but when they are bridged that means you have to have at least 4 ohms.
