I think just about everyone on here has missed the point of this guys question...he wants one brand front to back.
Now if you want DVD and all that crap (I say crap because I don't think it belongs in a car...just my $0.02) you will have to stick with a brand that makes all that crap...Alpine, Kenwood, Eclipse, Pioneer, etc.....personally, I don't think that they do more then one or anything all that well.
I think that by trying to match brands, you are making a huge mistake, and will end up with a sub par system at the price of cosmetics. Last time I checked, you listen to your system, not look at it

! While I agree that it's nice to have a nicely integrated system from a visual standpoint, you won't find anyone who is not sponsored winning competitions with one brand doing it all.
I know that you don't compete, by why sacrifice good sound?
There are only a few brands that I think do everything (minus a head) really well. My top two pics would be a/d/s/ and Image Dynamics.
ID has some of the best analog processors out there, outstanding subs, good mids (the IDQ8's were great as dedicated midbasses), and their horns work really well.
a/d/s/ amps are powerful, but a bit big and awkward to install. The cool thing about them is that you can install a whole system on just one amp (they start with 4 channel configs and go up to 8 channels...don't let the power ratings fool you either!!) They also have one of the more versatile crossovers around. I really llike thier comps, very laid back - the crossover construction is virtually second to none, and their subs are all SQ.
I have not heard JL's newest comp sets, so I won't comment on them...same goes for Kicker. RF makes everything but the DVD, but personally, I think that they are tyring to hide their poor quality with glitz and glam...take a look at thier new components and you will see what I mean..it has marking poured all over them.....when a company can't sell via their performance, usually they chrome it!
I think that you should skip trying to match everything, and find what company makes the best of each component that fits in your budget. Then piece those together to make a great system.
