I am using a Crown XLS1500 power amp and 4 speaker ( 2 x 10) cabinets 4 OHM's each cabinet. Right now I am running 2 speaker cabinets per channel which gives me a 2 OHM total load per channel. Is there anyway I can rewire the cabinets to where the amp sees a 4 OHM load per channel? Or all 4 cabinets together and bridge - mono at 8 OHM load? I am assuming that all speakers in the cabinets are 8 OHMS each. Thanks.
