Hey there guys I just picked up a crown xls402 off craigs for what I believe was a steal. I've gone to the modeling side of things and decided to go eleven rack into power amp into bass cab. So I did just that, I plugged the output of the eleven rack into the input of the power amp and the output of channel 1 of the power amp into my cab. After plugging everything in and plugging in a guitar (just to test it) I powered everything up and there was no sound whatsoever. I checked all the cables and found nothing to be wrong, I then plugged the output of channel two into my cabinet and voila I was able to hear sound. I bought the amp specifically to bridge it and use it for my bass. But can't for the life of me figure out what is going wrong, I have since unplugged everything and come to talkbass in the hopes of finding a solution before I fry something out of ignorance. Any advice?
