Ok, fellas, I need your help here! I am planning on changing out some of the audio component of my TL come this winter, and I would like to know what else I need to add to the shopping list to get everything hammered out. Here's the goal:

-Replace front speakers
-Replace subwoofers
-Integate DVD player to navi
-Some type of iPod connection

...simple enough, no? I have the amps and pretty much have the speakers selected, just need to know what I will need to integrate the above components.

Thanks in advance!
