For the most part, good car audio doesn't focus on visual design, but there is definitely a growing market for innovative automotive audio systems that are highly stylized. While almost all home audio systems simply used round subwoofers in square enclosures, you can find a number of flashier car options.
For instance, Stillwater Designs offers a square car sub, Bazooka produces a triangular sub, and Xtant has a popular new hexagonal option. If you are looking into subwoofers because you really appreciate an intense bass experience, a tactile transducer may appeal to you. Attach it to your amp along with your sub, and then place the transducer in your seat. Your body will then vibrate with the intense bass and drum sounds from your favorite music. If you are looking to assemble your own car stereo system piece by piece rather than purchasing a kit, you are likely to end up purchasing your subwoofer separately from its enclosure. The enclosure determines the particular qualities of the bass sound that will be emphasized. Your selection should be based on the tone that you like (flat, sharp, booming, and so on), the genres of music you most listen to, and of course, space constraints.
