I have an Audiopipe 3000D and it works just fine. Anyone who says its a crappy amp, has never had one and are judging the book by its cover/judging it by its price. People say its not clean power, but it only starts distorting if you have the gains set too high and it starts to clip, just like any amp out there or if the voltage drops too low due to insufficient electrical.
The Audiopipe 1500 would be a MUCH better fit than any of the amps you listed above. Those are all crap amps, especially Boss. If I had to rate the amps, I would say Power Acoustik, SoundStream, Absolute (Never heard of it honestly) and then the Boss.
But honestly it has alot to do with your install, the equipment, electrical, and what subs and speakers you will be running. May want to list those so we could help steer you in the right direction.
