I just installed Kenwood DDX-7019. I used the wiring kit from Crutchfield. Everything works fine, except rear speakers. They work, but are really quiet. Are they just that weak, or am I missing something. Is there a separate amp for rear speakers? Or maybe I'm missing something in audio controls on a new radio? (but I spent quite some time playing with all the options)
I have 2007 Base, with base radio.
Thanks for your help.
