Hey Clay, not sure what it is you're trying to do. Are you just wanting to add a "line-in"?
If thats it, do you want it to have its own Vol control, or controlled through the factory HU?
I'll try to do what I can to help, but can't promise anything.
BTW, I'm in Jacksonville, so we're pretty close. :-0
Love that Panda Chinese buffet down your way!
See ya, Dex
