That's a low power speaker, 100W RMS, so the 2002 would be a bit too much.

Need to use those limiters again, I prefer to limit to a lower value then the RMS figure, I believe 50W should do the job.

That's good to know. I'm guessing it's needed because the default configuration when you enable XOV mode is channel one for LF and channel two for HF.

I see your problem.

Two solutions you may try, one is to download and install Audio Architect software (free) from the harman pro web site, connect the amp to your laptop and see what configurations you have in there after you choose 2-ch sub.

Another solution is to call the crown tech support staff available here:

Let us know what you find out.

Hello again :)

No questions are stupid, only people who are afraid to ask them...

Not sure if I said it earlier but the subwoofer amps should get both the left and right channel signal and you should configure summing within the amp.

A note about power amp operation, you can't "back off" a little with power amps, all you do when you turn down the gain knobs is lower the gain, that means that all you will need is a hotter signal to get the maximum power of the amp. The only true way to back off is using limiters, both peak and RMS.

The frequencies built in those speakers crossovers should be the guide when you do biamp instead of passive mode, you should use 250Hz instead of the 375Hz as your starting point and tinker from there. 90Hz sounds good.
