Thanks for quick reply! The stereo is brand new i got it in december it cant be that because it came with a very clean and brand spanking new harness. put it in myself. so could it be the vehicle's end of the harness? i wouldnt think so because i remember checking them out when i swapped head units and it looked good to me. and yes I switched both speakers on both sides because first i thought it was speaker but NONE worked on driver side. so its definitely somewhere from door to other end of harness right?
