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.
