You know the cars that have the pounding booming rap music coming out of them? The ones with huge sub woofers in the trunk? Is this thing to do with cars and loud bass just a American tradition?
I think it’s widespread - this hobby/subculture definitely exists in Japan. Here’s a Google Image search for custom audio in Japanese.
I don’t know about boom-boom cars but boom-boom rooms are nice.
There are certalnly some here in east London, but I wouldn’t call them common.
The boom boom room? That place where Carl picks up strippers?
You’ll find such cars everywhere there are cars - they’re a percentage of every country’s car scene. The difference with the US is that it crosses various genres - you’ll find it in imports, exotics, old Detroit iron, everything. Outside the US, it seems more related to the Japanese import scene, or whatever cars emulate them.
I find them annoying when all I hear is boom boom boom. I mean, anybody can go to WalMart and buy a $99 box that goes boom- big deal.
“Notice me, Notice me” that’s all it is.
I am slightly impressed by the ones where I can actually hear music in addition to boom boom boom.
It cracks me up when it’s a POS car and you can hear the poorly fitting trunk lid rattle. Precious little musical enjoyment can possibly come from that.
It has nothing to do with musical enjoyment, it’s all about showing the world how big your dick is.
That was my point. 
More like showing the world how big a dick you are.
While I’m sure they exist, I’ve never noticed these cars whilst living elsewhere in the world. Here where I live now in Chicago, I don’t think a day goes by when a bass-blasting car doesn’t roll down my street. I’d say it drives me crazy, but I honestly have long learned just to filter it out.
Yes, basically American. It evolved from the post-war years, when only America had the economy to enable children to have their own cars, and outfit them according to their own taste, reflecting a pre-adult maturity of the car as a look-at-me toy, rather than a tool.
I prefer it to Harleys. And its not just an American thing, there are cars with hobby stereos everywhere. And some of them are pretty impressive, technically. Too bad the music of choice of their owners is generally pretty grim. And annoying.

That’s not music, its just noise 
Yeah, boom-boom cars blasting Mozart wouldn’t bother me so much. Funny how that never happens.
(I’m the guy who goes banging on my neighbors’ doors when they have loud parties. Only I don’t tell them to keep the noise down. I just want them to, for the love of God, play some less shitty music!)
It is a lot worse here in the Dominican Republic than I have ever seen (heard) in the USA. Down at the beach there will be several trucks with a dozen huge speakers blasting at each other.
My eyes roll so hard when someone answers with this reply that I nearly die. To death. Really. I know just as many girls with subwoofers as I do guys.
They aren’t just about making noise, they’re the only way to reproduce the lower end notes that occur in music. Tweeters are the same way at the opposite end of the spectrum.
I don’t have a sub in any of my cars, but I do have one in my home theater to reproduce lower end sounds. Since I live in the middle of nowhere without a neighbor within about 200 yards, it’s most certainly not used to advertise how big my dick is.
There is a huge difference between cranking up your home theater to listen to a movie when you live in the middle of nowhere and the average asshole that drives with all of his windows down, volume knob set to 11 and their amp clipping so bad the sound is distorted beyond belief.
Have that guy next to you at a stoplight and you will think they are an asshole.
Right, I’m thinking that he’s an asshole, not how big his dick is.
