I recently installed a new deck for my girlfriend in her Dodge Stratus. All of the wiring appears to be correct as I've checked it now almost 5 times, however no sound is coming from the main speakers in the front doors and the rear. The only speakers that do work are the ones in the dash and top rear and have absolutely no bass. I can't figure out why there's no sound coming from the main speakers. Please, any help is greatly appreciated.

 

I'm betting it has the infinity amp ... Ypu need to wire the remote line from the head unit (blue wire or blue white stripe)to the amp turn on line white with silver/black dots...
