    I have a 200 watt amp and a 300 watt cab. Does this mean I will only ever get 200 watts of sound out of my cab?

    Pretty much, but that puts you in a fairly safe range to crank the amp without fear of blowing speakers.

    Thanks. I hadnt thought of blowing the speaker. So its always best that the cab is higher wattage than th ehead.

    To the OP: use your ears and what is between them. If the cab sounds like it is going to blow then it will. Many cabs reach their mechanical limits well before their thermal ratings.

    Wattage ratings are, in essence, just numbers. Amps may put out spikes higher than their advertised ratings. Cabs can give out if EQ's and brains are not properly utilized.

    And this has been SOOO covered.

    The amount of power the amp puts out is determined by the impedance of the cab, not at what it's rated for. If it is an 8Ω cab and your amp puts out 200 watts @ 4Ωs, you'll probably get around 130 watts.

    If it is a 4Ω cab and your amp puts out 200 watts @4Ωs, you will get 200 watts to the cab.

    There are stickies above about this, although they can get annoying as heck to read if they're shown in a typical bickering thread type of format. ;)

    You might not even get that without blowing a speaker. See post #4.
