does anyone know what wires are what when you're tapping into the back of the stock stereo? i mainly need to know the speaker level outputs and the one that would tell the amp when to power up.

i have a 2009 xlt with the single cd/mp3 and sync. i want to install a amp and 4 new speakers because the factory speakers suck but i want to keep it looking stock

the long way;door panels off check color codes going too speakers?most head units come with power ant.leads(blue?) this will tell the amp. radio is on

k.black

remote=blue=turn the amp on
speakers=seperate harness each having a postive and negative as same color
