i got the standered cd wih the 4 speakers on 1500 ram 06, wanting to do some audio upgrads (not sure its worth it cuze i got the line in jack right in the front for any mp3 player)

but does any one have a diagram of the audio system, wiring, speaker specifications, size, where the amp is and headunit info?

 

Go to crutchfield.com and you can find your speaker sizes there.

 

I have a manual with all info for 2006 ram with diagrams.

 

The standard cd player has the amp built into the cd player. I would suggest a new head unit and front door speaker upgrade.
