I think that's a good idea!
Wow, never thought of that. I think it would be cool. Even without pre-outs you could just route the speakers through it's high-pass filter. Then if your surround speakers are small, you can let your real sub handle it's own bass track without having to handle the bass for the rears. You'd probably want to put your surround subwoofer between the two rear speakers. I think you'd get a pretty good sound. Maybe if you had a lend of a subwoofer, or something, you could try it out and see what happens. If you try it out let us know what happens please! :cool:
