Ok this may be a stupid question, but I dont claim to be an amp guru. I will admit that it was plain stupidity on my part for not catching this much sooner. DUH@ME My 4x10 cab is rated at 8 ohm, my 1x15 is rated at 4 ohm, Am I in any danger of ruining my head or speakers? I really cant believe I didnt notice this when I got it. My Head is rated at 4 & 8 ohm if that helps any.
