i've had it since I got the car 2 years ago.. it's an old sony 2 channel, maybe someone's dealt with sony's before? well i finally got new components in.. fire everything up, no sound and the offset light comes on. Whatever that means.. checked all my grounds, power, speaker wires. All good. So i stick in my sub amp just to see if the speakers worked and they did, albeit quite bassy The sony amp also blew a fuse when I started the car. Anyone have an amp they wanna get rid of?
