I just bought my second Titan. Its an 04 SE w/ the 4x4 tow package and Rockford Fosgate Sound System. I was wondering where I could get a user manual type deal for it explaining all the specs of the system and how it is set up. Does the amp under the seat run to all the speakers as well as the sub, or do the speakers not run off an amp? I love the truck as much as my other, but I am a bit disappointed with the aux input. Maybe its just mine, but it sounds like complete crap. The vocals come through like background noise and there is no thump. My other trucks aux input (from an aftermarket HU) sounds just as good as having a cd in. Any thoughts on this or similar cases that any of you have found fixes for? This is quite a nice truck and am really pleased with it.
