I bought my 97 dodge ram a couple weeks ago. It had an aftermarket stereo in it, but I decided that I would put mine in instead. Who ever installed the previous stereo did a horrible job, and didn't use a wiring harness. I was able to connect all the wires myself with some butt connectors, and tape. Everything powers up on it, but the music only plays through the tweeters, and not the speakers (which I just replaced the speakers a week ago.) has anyone had this issue, and/or know the way to fix it?
