Default Combining channels for sub

Hi all,

I want to build a powered sub-woofer. I've found designs for an active crossover that will cross over at 2Khz. http://www.linkwitzlab.com/filters.htm#3 Great!

Now my question: This is fine if you want to run two sub's, but I want only one sub so presumabely I need to combine the left and right channels at the output of the active crossover.

How do I do this? Can I just connect the channels together and run them straight into my mono amp?

you have to build a crossover for each channel and just couple the outputs toghether. You also may need buffers depending on the impedance of the amps.
