I was just searching and saw these.

AudioSource AMP100 - $99
Which the specs state...
"Output power 50 watts RMS per channel @ 8 ohms, 60 watts RMS per channel into 4 ohms, 160 watts RMS @ 8 ohms bridged mono"

And
Dayton Audio APA150 - $128
Which the specs state...
"Measured power output: 2 x 75 watts RMS (into 4 ohms @ less than 0.01% THD)"

I know that 75 watts is not 100 watts, but the trick I learned years ago about bass shakers is that they don't need to be "cranked up" to be effective, and in fact, they are more impressive at lower settings...

Other thoughts about any of this?
