I play music from my iphone through my original am radi0/center dash speaker, but it's not loud enough. A tried adding a bluetooth speaker, but it instantly shut off the dash speaker. So I need to use one or the other, unless I'm doing something wrong?
Isn't there another factory location other than post #301955 that's attached behind the seat via the sheet metal bracket? Anyone have a pic of the original location?
