This will send the full audio signal to your main speakers including those below the specified crossover frequency I recommend setting the crossover freq at 80hz to start. In the speaker set up menu of the 3808 you should set the FL and FR to 'Large'.

I am assuming with an onboard sub the speakers can be run full range. I tried searching for some information about your speakers but I couldn't find any specs other than the fact they were made in conjunction by Polk and Genesis. I am not sure if I am using my equipment correctly. I am in the market for a new cc also, so I guess I do not need one w/ pw sub? If I use the crossover freq at 80Hz, does this apply to the pre outs also? If it does, I guess the pwrd subs on mains would not be active, correct. I am not used to having a seperate powered sub, and I am still trying to see how it fits in. The other was for listening to music in stereo. One, I was trying to get the full range of fronts in 5.1 setting. I then moved them to the left and right (frt) pre amp outputs for two reasons. Originaaly my pwrd subs on mains were used as LFE, before I purchased new sub. Honestly, If maximum performance is the goal I think he would be better off getting another sub and splitting the Sub out just once and/or tweaking the crossover freq until everything is blended just right.[/QUOTE My personal experience with this is that using a dedicated sub for the LFE channel and running the fronts full range gives the optimum (not necessarily maximum) performance. If he wants to use a splitter from his Sub out and use his dedicated sub as well as the onboard subs of his mains then by all means: try it and see if you like how it sounds. I A/B'ed this for awhile using several sources and I could not tell the audible difference, so why bother with the extra cable? What if any difference he would get using the pre-outs in conjunction with his high level connection is beyond me.

For example, my center channel has a low level input that the manufacturer recommends using in conjunction with the high level inupts as well as the Center pre-out of my receiver (and NOT the LFE channel). Honestly I don't think the OP was completely clear if he was intending to use the low level LFE input on his mains for the LFE channel or simply was trying to 'squeeze' the most performance out of his FL and FR channels.
