Your welcome and anytime.
You do have the Alpine system?
Based upon your setup, you are going for the traditional front, rear and subwoofer setup. Do not go after the center channel speaker. Keep to the front 6x9, the front tweeter and the subwoofer.
This is an interesting thread you should read from last year:
Factory Frequency Response
The Mosconi works the best when it gets the 20-20k signal. Then you will be rocking. If my budget would have allowed me, instead of the Rockford Fosgate 3.sixty.3, I would have gone for the Mosconi Gladen 6to8.
Make sure you watch the video from JL Audio on the Cleansweep.
Best for now.
