I have a couple of questions for the board:

1. Who makes the changer for the Visteon P100I+ which I believe is the Mach head unit in the EB premium sound package. Others on this board say it is a Clarion but it looks identical to the Alpine Changers.

2. If it is a Clarion or Alpine, will I be able to use it in a head unit upgrade (Clarion/Alpine)? If so, do I need a special adapter/converter?

3. I have read that there is not an external amp in the 1999/2000 premium sound package. If this is true, I should be able to use line level outs from a new head unit to power factory sub?

4. Does anyone have pictures of component speaker installations? Will a 6.5" woofer work or do I need a 5.25"?

Thanks for the help!
