Ok, so I've done searches and read through different threads, but I still can't seem to find my answer. What I've gathered from other threads is that it is pretty much safe to put 2x the RMS watts into a cab, as long as I don't run "on 10". Is this true? For example, if my cab is rated at 500 watts RMS, is it safe to use a 1000 watt head, as long as I don't max out? I'm sorry if I'm being unclear, but I'm very confused on the subject. Thanks!
