You can do much better with your $100. May I suggest:

Insignia NS-R2000 (100 wpc ) receiver - $67.98 at cowboom.com
Dayton B652 6 1/2 inch speakers - $29.00 at Parts Express

The Dayton DTA-1 Class T digital amp is $44.80 at Parts Express and it will drive the B652 speakers nicely at normal listening levels but it won't rock them like the 100 watt Insignia receiver.
