I have a 2010 chrysler 300 and I decided to upgrade the audio system but when I was done I had no sound from the 3 dash speakers. Now since this happened I got rid of that deck and have since replaced it with a 6.2" touchscreen and still the dash speakers dont seem to be working. Any ideas on why and how I can fix? I'm not to car savvy if you will but have put sound systems in every car I've owned and never had an issue. Also does anyone know the speaker sizes of a 2010 chrysler 300?
