"Same" is damn hard to say, as the acoustics of the two are in such different settings - cabinet in a room v. door panel in a car with road noise. But, as far as good products, priced fairly, and at the cutting edge of design, look at CDT Audio. They build speakers for other companies mainly, but you can get their speakers at a few authorized Internet dealers. I had the Classics and they blew away my Boston Acoustics in terms of sound quality. Then I upgraded to the Euro Sport series (carbon fiber driver) and welcomed another great increase in performance. You can tell the mindset of the company by looking at the cross-over upgrades available - many of the cross over networks cost more than the speakers.
Warning - they are not flashy, so if you want chrome and bling, not for you. And they do like gobs of powers, so figure on a new JL Audio (or such) amp with at least 75 real watts to make a pair of components sing.Best car audio speakers I have owned, and I have owned many, and auditioned many more.
If you want subs or amps, I can only recommend JL Audio, as my high-end Alpine excursions have been disappointing. On the other hand, for a head unit, I strongly recommend Alpine over all others.
There goes my two cents...
