FMOD Crossovers not working??.... tweets are playing mid/lows!!! static with HPF

"Your headunit has the option to "biamp" which should allow you to set the internal crossover of the RCA outputs to around 2.5 khz - 3 Khz."

I dont get this? I swear Ive been through every audio function of the thing and didnt see anything like this.

I would have PREFERRED to cross the tweets @ 5000, but couldnt find a solution that was in my knowledge level without going to a audiocontrol box for alot of $$$

I cant find anything on this, the deck has 3 sets of preouts, so if I was able to switch the frequency on just one of them, Id be golden, btu Ive just never seen that on this deck when playing with it
