I am so lost and have no idea what to do. I havea 1996 Stratus. The speaker covers and stock deck dont say Infinity so im 99% sure its just a stock system without a factory amp. I installed my aftermarket stereo same as I have in 3 other cars and the radio works just fine. However when I plug in my rca's into the back of the deck to run to my amp it turns the back 6x9 speakers off and then my subs still dont work! I am so lost on whats goin on here, any suggestions would be great!

 

are the 6x9s amped or do they run off the head unit? what all does the amp push and wat does the h/u push
