Oh yes, that should be plenty. Another thing with the power. Pretty much all of us know doubling the power sent will give 3 more db, but we forget that going 3 db down will be half the power. So if you have 10 db of headroom before you max out your amp (say it's a 200 watt M200), that's only 20 watts. Just 3 db down would be 100 watts.
