I'll preface this by saying that I know VERY LITTLE about car audio. I bought an Alpine 135BT head, kenwood 500 amp, 2 Rockford 12" subs, and speakers. I got it done at a car audio shop. They left my rear speakers in. I had my folks pick the car up for me cause I had class.
The issue I'm having is that when playing music on Bluetooth, USB, AUX, or even CD, I'm getting 90% of my rear noise from my factory speakers and VERY little sound out of my subs. When I play the radio however, all of a sudden my subs come alive and the **** pounds.
Anyone have any idea what the issue may be?
