2005 G6 - Speakers dropped out - no bass or midrange
My son thought his speakers were blown and we were going to replace them, but we found something weird. Only the lines for the high range (tweeters) had any signal. The bass and midrange have none. This is true for the front AND the rear speaker. I have managed to rig up some 3 ways in the back using the tweeter input so he at least has some sound, but I can imagine what is wrong with the bass/midrange. I checked the wire harness coming from the amp and it is tight. I have checked the amp fuse in the trunk fuse block.
Any ideas are appreciated.
