Am I the only that has actually plugged the phone into an fm transmitter to use with my car stereo? Of course i am, you kids all have your bluetooth radios and your xms and syriusnessess. When using Pandora, the bass is much much louder in froyo than it was in all previous roms. Kernel with modded sound or not, the bass is big. So, yes, the sound is very different from what it used to be. Mids are too high and highs are meh... nonexistent. It doesn't sound bad on the phone or through earbuds, but unless you like rap, you probably won't like the sound coming through your car. But, I don't think that's anything some decent equilizer software can't fix. Personally, I think the sound is an improvement despite the focus on the lower end of the spectrum. In previous versions, it was to light and airy with no lowend.
