I purchased this beautiful 200 c230k last week. The car is in great shape other than the headliner sagging and the fact that the speakers dont work. It had the stock stereo when i bought the car, but i purchased a cheap boss stereo to replace it. I also bought the wiring harness specific for this vehicle. I connected it all together and the radio powers on but there is no sound what so ever. I thought maybe the speakers were done for. So i checked the door speakers and they were shredded with no material around the cone. I replaced the door speakers and still no sound. Ive checked the fuses and ive also looked for the factory amp, but i dont think this car has a factory amp. Im at a loss. Ive connected several stereos systems in the past in several different cars but man this one really has me confused. I would greatly appreciate any suggestions.
