Crown XTi Amps and JBL Speakers - Do I need an additional crossover? [message #28387]

I recently purchased the following for our church's new sound system:

1 Crown XTi 4000 amp
1 Crown XTi 1000 amp
2 JBL MRX525 speaker cabs
1 JBL MRX528 dual-18" subwoofer cabinet

It is my plan to run the 2 MRX525s in stereo using the XTi 4000. I also plan to run the MRX528 through the XTi 1000 (bridged).

My question is this: Will I need an additional crossover to go along with these amps, or is there a way to link them together and use the built in crossover?

I thought about simply messing with the DSP on both amps to send certain frequencies to the mains/subs, but I'm not real sure what I am doing since this is my first real experience doing pro audio stuff.

Any advice and/or help from one of you out there in Forum-land would be greatly appreciated. Thank you.

I would run the sub with one amp and the mains with the other. Just make sure the subs get content below 80 to 100Hz and the mains get the content above 80 to 100Hz.
