Aftermarket woofer & stock tweeter

Hey guys.

I've got a '00 VW Golf.  I just hooked up some Rockford Punch 163s for some better sound.  They're 3-way speakers.  But with my stock tweeter being up at the edge of the window frame, I wanted that hooked up to have the high-frequencies still come at me from a higher point in the car.  So I just wired that tweeter in parallel with the Rockford 3-way.

My question is, would this cause an end result of a 2-ohm impedance?  Or because of the filtering to each speaker do I still have 4 ohms?

Thanks guys
