Hey, I've got basically a two-part question... I bought a used GK cab (4x10) and I was wondering if there's any way to figure out how many watts it'll handle. It doesn't say anywhere on the cab. I contacted GK and gave them the serial number. They graciously told me it was probably 1982 410EB model, but didn't have any more info about it on hand. So, I was wondering if there's any way I can find out... or, if anyone might know the specs on a 1982 GK 410EB (a long shot, i know). Thanks!
