Hey guys, new here. I've searched a long time on the net trying to find a answer to this. My daughter has a 2007 fj with base cd player. Since she bought it, (few months ago), the only speakers that worked were the "exciters" in the headliner. Chalked it up to a bad head unit. Just installed a Pioneer AVH210-EX and still no sound except the exciters. I do have new speakers for the doors and dash but cannot believe that something is wrong with all four speakers? Is there a connection somewhere between the stereo and the speakers I am missing that I can check? Thank you all in advance...
