I might get an svt 3 pro this sunday. I have a peavey kb300 with a 15" speaker, 8 ohms, 200w rms, 400 max. I figured I could wire the KB300 up as a cab until I get something better. The SVT3-PRO pushes 275w @8ohm, 450w@4ohm My question is, if I were to get another cab, for example, a 400w, 8ohm hartke 410, would i run the risk of blowing the 15? or would the 15 only take what it needs? I do realize I could just use my ears and turn it down if it distorts, but I was just curious how the wattage would be divided, being different wattages. I tried to search it and look on the faq, but couldn't find anything, although i'm almost positive i read something on here very similar within the last couple days. My apologies, I'm sure this is probably a question that's been asked many times. EDIT: To clarify, I do realize that together the cabs will equal 4ohms, bumping the amps wattage to 450.
