Can anyone tell me the speaker diagram for the 2009 Dodge Challenger SE? I am adding a Kenwood amp and Kenwood speakers to my Challenger. The factory stereo does not have rca jacks out of the back, so I have a hi/low converter and I am splicing into the back dash speakers. However, I don't know the rear left pos and neg and the rear right pos and neg. Any help would be greatly appreciated.

Thank you,

Mark
