Well, I finally got around to buying drivers and the 'cheap but good' crossover components. It's all assembled, wired up and ready to go. All I need is a cable with a speakon end or an adaptor. I'm kind of scared, fearful I guess, to try it. A little scared that if I made a mistake I'll blow up an amp. Is there a good test that I can perform to it before I hook it up? Thanks!
