    Berhinger pmh880s

    Hi I am wondering if anyone could help me I bought a berhinger 880s last year when I was doing some upgrading to my outdoor theater. Well things happened and didn't get to finish it till this year I finally ordered me some new passive pa speakers so I could run them off the powered left and right channel on the back which is 400 watts at 4 ohm but for some reason when I plug into the b channel it goes to making and alful noise but the a channel is fine could anyone give me some advice what could be wrong the past speakers are 4 ohm as well thanks
