I feel like I'm doing something wrong, I have 2 Kenwood Excelon KFC-XW1224D's

and running on a SoundStream DTR1.900d amp

But, I feel like I'm tuning my amp wrong. My system sounds good, but doesn't really play lows.
Is it because I have both the Low and High Frequncy knobs turned to the same place?
Thanks
