this is not tractor related, but I know that someone will know the answer on this board. I have a 1995 Dodge 3500. When I got it the truck has the factory radio with no CD, or other hookups. I recently installed a new stereo and it was pretty simple. The problem is this. It sounds awesome when the radio is playing, but when you put in a CD or MP3 it has no low end at all. You can move the sound to the bass speakers and you can barley hear it when you put it 50/50 front and back it sounds louder but like crap. What is my problem. The low end is fine with the radio on. Any advice appreciated. Thanks in advance.
