i am installing a sony cdx-gt510 h/u into mu 03 stratus and i am only getting sound with the radio source. both the cd player and frontal aux dont produce any sound but the analyzer bars bounce so i assume some sound is there but wwhat happened to it. the factory h/u never had this problem so im confused. the wiring harness is connected correctly to my best knowlegde but the car has the 7 speaker infinity and i'm confused if i need to connect some other wire or something. thanx for any help. i'll can include some more details about my wiring if needed.

 

PLZ!!if anyone has fixed this problem can they let me know! i have the exact same problem. ik its an old post but still any help would be very helpful!

 

Welcome to DF
I had a kenwood installed in my car, but I let bestbuy to install it. Because of this reason. As far as the older post, they never posted back. If you have an infinity system, you may have an amp to go thru for the speakers.
