I don't understand how this could be a wattage issue, since this is an
auditable difference at low volume levels. A few years ago I was running a
1200 watt 4 channel Pyramid bridged in to a pair of 4ohm 12's and it powered
them nice and loud, but there just wasn't any low bass at low volume levels.
Then I replaced it with a Kicker IX704 amp which had loads of grindage at low
volume levels. But oddly enough it did not hit as hard at high volume levels.
It's not just the Pyramid, I have a pair of Profile amps here that act the
same way.

Where
more costly amps such as Orion, Kicker, PPI and MTX seem to produce deeper
bass at lower volume levels. I also found that these cheaper amps seem to
run
a lot hotter. The only reason for this that I can think of is an
inadequate
power supply.

No, that's not a problem. Every "cheap" amp I've ever tested has a flat
frequency response down to 20 Hz (lower in fact). This is well documented
actually. What you're undoubtedly experiencing is a lack of power. Use a
bigger "cheap" amp and you won't run into this.
