How To Properly Bi-Amp (Sonic Frontiers Line 2 to Two Amps to power Infinity Kappa 9's)


I recently purchased a pair of pristine Infinity Kappa 9's and I am looking to biamp them. I have a pair of Kappa 7's that are using a Behringer Europower EP4000 amp and it works great.  The Ep4000 cannot handle the 9's.

I am confused as to how to split the signal coming from my preamp for proper bi-amping. Do I just buy a split balanced or RCA cable? I feel like this would compromise the signal... Or do I use the additional outs on my preamp? My preamp is a Sonic Frontiers Line 2. I believe it has two stereo XLR outs and two RCA outs.

Please let me know.

...also, what is an powerful enough, extremely holographic, silky sweet amp for the mids and top section of the Kappa 9's? Suggestions would be greatly appreciated.

Thanks,

Thanks for your reply.  The Infinity Kappas already have a crossover setup specifically for bi-amping. I do not think I need an additional external crossover, although it would increase the efficiency in amplification. 
One of the Crown XLS amps I am using has an internal crossover and I will employ it.

Still, how would one split an output signal from the preamp to feed the two amps? Should I just use the multiple outs from the preamp?
