I just ordered the Alpine Spr-175a 6 1/2 components and I am deciding where to mount the tweeter.either on the door panel (the "arm rest padding part near the window) or on each pillar above from the defrost vent. I want to ask three questions:

1. Where should I install the crossover?
2. How do I route the speaker wire to the amp through the black covering from the door jam to the frame?

3. how does the tweeter flush mount on the door panel?

 

For #2, see my webpage....
