    I've been talking to tons of people. Some like double the amp rms to speaker rms. some like same. some like half. I have no idea. I think more is better, I order extra large just cause it's 20 cents more, but seriously is there some "rule" that I should go by. Does speaker efficency effect head room needs? I'm thinking of building a rig and have no idea. help...please.
  2. Do a search on 'headroom' please. There are a few good threads that explain the concept of 'headroom' quite perfectly... I'm sure those threas will help you out.
  3. Like you post says, there are a lot of different ideas about how much power to cab ratio you should use. I use a PLX1202 that is 600 watts at 8 ohms bridged and I run it into a Hartke 4.5XL that is rated at 400 watts and 8 ohms. It will play much louder than I ever need when I play out so I'm happy with it. A lot of people are worried about blowing speakers by using an amp that is too big for their cab. My biggest concern is not that I will be playing too loud but that something electrical or mechanical will cause the amp to output its full power for a sustained amount of time. For this reason run an inline compressor and keep my pre-amp set pretty hot with the power-amp volume turned down. As far as a hard and fast rule, I don't think there really is one. Like Bob Lee quotes "If it sounds good, it is good"
