Paralleling chips doesn't really increase power. However, when chips are paralleled, they'll share the load and you'll be able to drive more easily low impedance speakers.
By example, when 2 chips are paralleled to drive 4 ohms speakers, each of them will "think" that an 8 ohms speaker is connected.
If you want more power, try the Bridged + Paralleled schematic.
Hope this helps !

I can't guarantee you that you'll get 100 Watts (depending of your IC) but I'm certain that you'll have no problems driving 4 ohms load.
By the way, the schematic you posted is very similar to the one provided by National Semiconductors in their application note :
http://www.national.com/an/AN/AN-1192.pdf
Take a look at the schematic "PA-100" (Parallel, 100Watts)
If I'm correct, the schematic you posted is based on the Bridged + Parallel configuration found on this forum right ?
In the application Note, you'll find several combinations such as :
BR-100 (Bridged 100W)
PA-100 (Paralleled 100W)
BPA-200 (Bridge + Parallel 200W)
You have the choice !
