I left my car at home for the winter while i was at school and i recently started driving it again. As i expected it had a couple of problems, so i brought it to my mechanic to fix it. After i got it back i tried the radio/cd player and found that I could barely hear it even at max volume. Im not saying its something the mechanic did, cause i never checked the sound before i took it to them, but does anyone know whats up or if theres something i can do to fix it myself?
