powered sub to an Adcom speaker selector box

I have an Adcom 5400 amp with a Adcom GTP 350 preamp . The amp is connected to an Adcom 3 speaker selector. I also have a Kilpsch  R-100SW as my subwoofer. Can I hook the subwoofer directly to the speaker box like a regular speaker and turn the low pass to around 80hz.  The other two sets of speaker are 901s. I can't find it anywhere but it seems as feasible as wiring the subwoofer in line with one of the speakers as many do. The speaker selector is passive.

 You can't do that. That subwoofer has line level input only. The only way to hook it up is from the preamp outputs to the inputs on the subwoofer.

If I only have one preamp output ( to my amp) on my preamp, am I outta luck for hooking this subwoofer up?
