Is my amp the problem?

I recently decided to bi-amp my speakers so I purchased a crown xls 1002. (225w 8 ohm). I am driving a 10 woofer. It sounds horrible. I can't seem to get it to put out much power despite its rating even when I make all the right adjustments. Its a class D amp. Is that my problem? It just doesn't seem to have any Ba**s. Lol. Advice is appreciated.

Looking at the specs, the gain on these Emotiva amps is 29db, where the gain on your modwright is 26db. If you don’t use an active crossover, you’ll probably want to use a speaker LPAD attenuator (parts express) on the woofers to bring down the level. Or spend more and use a passive preamp before the woofer amplifier.

my woofers are 86-87db sensitivity. My mid/tweeters are 90db,

So, if you have an lpad on the mids/tweeter, you can remove it and have absolutely no wasted power at all! Though, you might want some attenuation somewhere. Even 1 db on the woofer can mean the difference between something "too warm" and something "just right" (or even something "bass shy").
