I just purchased my 2017 Lexus IS200t and it has the basic stereo package. I am upgrading the door speakers and noticed when I was taking out the drivers side door speaker that it has little volume coming out. Most of the volume coming out of the speakers are from the dash speakers. When I put in my new 6.5" speakers with the new bracket, barely any sound comes out. Is there a resister that's causing less power to the front doors?
