How to wire Infinities to alpine hu?

Just got some infinity kappa 652.5i's and am a bit confused on how to wire them up.

I have an older alpine headunit and stock delco stereo system.

Now where i get confused, my kappas have an external crossover so there is seperate sets of wires to the tweater and midwoofer. It takes 2 wires for input.

Now, the stock delco speakers get 4 wires, 2 for the tweater, 2 for the midwoofer. I am under the impression that there is a factory crossover somewhere. Where is it so that I can bypass it? Also, would just splicing the positives and the negatives work?

Stock as in no Monsoon? If so then i think you hook up your one input wire to the tweeter inputs and hook up both outputs from there. At least thats how it is on the higher end Polks. Now if you have monsoon then you are gonna have to re run speaker wire to your HU from the factory locations. Or better you should install another AMP and run your speaker wires to there.

No monsoon on this. So can i just use the positive and ground off of the tweater to give this the signal?

What i am asking, is this signal to my delco speakers already filtered by a crossover or is it the same signal being sent to the tweater and midwoofer?
