Dynaudio, MB Quart, Infinity and Focal make fantastic component car audio speakers. Genesis(England) make very high end amps and speakers. Try www.Theautophile.com. Mr. Peter Lufrano if I remember correctly and ask his advice. Not sure if his advice is still free though. He wasn't real keen on giving free advice unless you were buying something from him, but there is no denying that the man knows his car audio! It all depends on where you are wanting to go with your car's system and how much $$ you want to spend. It isn't all neon and boomy bass! I love my truck's system!
Car Audio
Why is there no really high-end car audio other than maybe Seas Speakers, and McIntosh components? At least, there is no really easily-accessible stuff out there on the internet?! I would love it if Audiogon created a sister site dedicated to mobile audio. I am in my vehicle and at work much more of the time than at home with my HT and 2 Channel systems!!! Know what I mean?
