Have never owned quality speakers like these in a car. In Australia these are quite expensive but through Sonic it made the purchase quite easy as the savings were massive. Bought these on the recommendation of some professional installers and I am not disappointed. The bass is very impressive to the point if you didn't want to put a sub in your install or were limited to being able to put a sub in, you would find that these speakers do quite a good job of belting out the bass on there own. I have them powered by a PDX F4 and I am running the speakers through an alpine PXA h700 which creates an incredible sound stage. If you're prepared to part with the money you won't be disappointed with the sound.
