A doubling of amplifier power results in an increase of 3 dB in volume so a jump from 250 to 500 W gives a 3 dB increase and a jump from 250 to 1000 W gives a 6 dB increase because power doubles again from 500 to 1000 W.
There's lots of references to this available on line.
I wouldn't say that you "get more bass power". It may certainly sound like that but what's going on is a result of the sensitivity of our ears at different frequencies and sound pressure levels. The ear becomes increasingly less sensitive as frequency drops so for 2 sounds, one in the bass frequencies and one in the mid range, the sound in the bass frequencies will be perceived by us as less loud than the mid range sound. Increasing the sound pressure level produces a perception of a larger increase in volume in the bass than it does in the mid range because the sensitivity of our ears in the bass range increases a bit as sound pressure level increases we perceive the level of bass increasing more than the level of the mids when both get the same increase in sound pressure level.. Both the bass and the mids get the same increase in power as you increase volume, and it takes the same increase in power in both ranges to get the same increase in sound pressure level but we perceive a greater increase in the loudness of the bass frequencies for that increase than we do for the mid range frequencies. That also contributes to the greater sense of dynamics at higher sound pressure levels that we perceive.
