[QUOTE="PowerNaudio, post: 1101417, member: 561215"] i think the idea behind a quarter wave or transmission line is to make a small speaker sound bigger, by doubling the out put of the speaker by wave length calculations, and the length of the port, or folding of the port makes the box pretty big. i might be wrong. ether way, they weren't meant to be placed in a car. if you do want one in a car you can. but most likely have to go with a small sub 8" , the box will still be big, unless you go with the "snail shell" design or something like that, i know there is a guy on sounddomain.com with some cool designs for these king of applications and big sub 15" and the box is a pretty decent size. i have never heard one of his boxes. but he states that they are pretty loud, these guys are selling them, [URL="http://www.powered4sound.com/"]powered4sound[/URL] [/QUOTE]
