06 charger amplifier

I bought a used 06 Dodge Charger and the person before me had some aftermarket speakers in it it with an amp..  Only the dash tweeters work right now, and there should be 4 other speakers working.  I looked under the dash by the gas pedal to look at the amp and theres only 1 wiring harness plugged into it, and 10 wires that are cut and hanging out.  On the amp it looks like theres another spot for a 10 wire harness to be plugged in - Could anyone tell me (if you have a stock charger) if theres 2 harness' plugged into the amp - I hope I dont have to find another harness for this...

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

Right, I found the same thing.  I guess im trying to find another Charger owner - and see if they have 2 wire harness plugs into the factory amp...  If so or not where those wires came from.
