Are you powering them just from the battery or is the battery in a vehicle. You're probably not getting enough voltage or amps to them.
250-300 watts keyup for the m4v is not bad but you should be getting quite a bit more peak power on the modulation.

Those amps don't need a big drive, 2-4 watts keyup from your radio is plenty.
