So my girlfriend bought a 2008 Prius with audio problems, this is non JBL audio car. The only noise comes out of door tweeters. Today I tried replacing the radio and realized that Prius radio has 3 connectors on the back. I was able to connect 2 of them with the Metra 70-1761 harness. There was no audio. Was i supposed to get a Prius specific harness? My next step is to check out the speakers but i really dread taking door trim apart. Has anyone had this issue and resolved it?
