Car Audio Speakers

I know this rarely if ever pops up on Agon. But I'm in the market for speakers for my car. Anyone have any experience with high quality car audio speaker brands that can rival audiophile speakers? I'm pretty clueless. Most of my experience in car audio comes from those idiots who blast their distorted one note hip hop/rap bass at an intersection on weekend nights.
On the subject of factory systems, I recently had two different Jaguar XF loaners from the dealer. One had the standard sound system, and one was a luxury package with a B&W system. They both sounded pretty good, but I was a little disappointed that the B&W system didn't knock my socks off. I'm told the one in the top-of-line XJ is much better. Anyone heard it?
Focal, Dynaudio, Butler and McIntosh seems to get a lot of recommendations. Thanks.

For all the audiophiles out there who are looking for the best sound gear for their ride. However, be aware that the benefit of improved performance will come at a cost. There are still some products in the market which give good performance and have a great budget.
