"Boom Car"
 

So I just found some people calling cars with audio systems that were "too loud" to be "Boom Cars" ... never heard of them in my life ...

Any history to this word or if it relates to anything today?
Any qualifications (db wise) to become a "Boom Car" ...

Does anyone actually use this term???

that is an old term that was used by us law makers when trying to ban loud stereo's. atleast thats how i remember it.

Did these people happen to be really old people?

you must have been hanging out at RFD

Maaaaaaaaybe :)

This term is from back in the early 80`s. There is even a rap song about it.
