Can’t Solder

Ngen33r, where are you located? I bought 2 used Klipsch sub 10 subwoofers ( with quintet III) from Goodwill auction. I liked the first speaker set with the Quintet III so well that I got another set with the sub 10. Both worked fine, until the second started blowing fuses. Now my first one has no sound, but the power stays on. They are probably not worth fixing. I contacted Klipsch, but they won’t give me a schematic on them. I probably can’t fix them anyway? From what your writing, it sounds like there is no way I can cheaply fix them?
