How did you connect the woofer to the tweeter? Im putting in an amp for all the speakers and it has 4 channels. The 2 fronts with the 2 rears. I dont know how the tweeter connects with the front woofer. If you somehow connect them both then that will increase the Ohm im sure but, exactly how do you connect them?

Ive heard the OEM tweeter uses a passive crossover. Is that a seperate box that you have to replace wires with or is that in the tweeter itself?
