If your mp3s sound bad, just switch over and listen to SIRIUS for a while. When you switch back to your mp3s, you won't believe your ears.
I lol'd on that one ! That's the truth for sure. I have people that think I'm nuts because I won't subscribe to Sirius. It sounds so awful :(
I'm pretty happy with my car stereo now tho and actually surprised the Memphis Power Refs sound as good as they do. The gain on the little Alpine amp isn't even turned up but to 1/3 due to some alternator whine that has to be tracked down. I'm not all that worried about it since it sounds so much bette than before.
