Great SSF, You have microscopic eyesI was browsing the net for some details of this amp and this is what I found. The manual found at
Manual at accessories4less.com gives an idea of the specs of this amp. (Page 23)
100 W at 40 hz - 20 khz 0.2% THD
THD 20hz to 20 khz 50W @ 8ohm - 0.2%
See how the figures can be misleading. Nonetheless, 50 W should be more than enough for your requirement.
When i was interacting with Taga support team (Poland), regarding RMS power comparision with other brands, He replied like below
"this is real rated power ; some amps show huge numbers in paper specs but actually are 50% or more weaker "
