It is not good for competitions. It works wonders for daily and 'wow' factor. It's too strenuous on electrical for proper burping and the push/pull make it incompatible with SVC woofers or an odd number of woofers. It also is a higher ohm load than most other 10ks and won't go near the high spectrum of input voltage. Those are probably some of the reasons. As far as 10k amps go, she's dirt cheap.
you're right...for competing it's not that great. For daily it would be better. We had the proper electrical for them, just didn't put up #'s like we thought it would
It definately has it's place though and they can be had for good prices
