I have heard some MB Quart car audio speakers in the past and I loved them. I think I remember reading somehwere that they have been bought out, but I could be wrong. I have JL Audio XR series components and coaxials in my car, and they sound good, but if I had it to do over again, I would go with a system that has soft domed tweeters like their VR series. I have also heard some really good things about the eD speakers. Boston makes some really good sounding car speakers as well. But just like home audio where your room makes a difference in how the speakers sound, your vehicle, and how good of an install is done makes a huge difference in how they sound.
