Well, even more interesting than that, is something that people can't wrap their minds around...
We're living in a world of "cheap amplification" I guess..
...the relationship between "power" and "loudness".
It takes a power increase
larger than a 4x increase in power, to effect not even a 2x increase in output.
(theoretically, it would be exactly "4x" and "2x", but you have to factor in losses and inefficiencies like power compression as well, in reality)
Which means "increasing power" isn't a very efficient means of increasing loudness at all - and unless you are really feeding your sub a piddly little amount of insignificant power to begin with, chances are it can't take 4x whatever it is you are feeding it currently.
It's ludicrous then, to see someone taking a small amp, and clipping the hell out of it - and why? "Well, I don't have many watts, I need to squeeze out all of them I can get!"
I always try to get people to not worry about power, and worry about their enclosure instead - make that ideal for what their goals really are for their system, rather than trying to "brute force" something that is stacked against you to begin with.
