Slang for bass speaker(s), usually installed in cars occupied by angst-filled youth. Dubbed "whomper" due to the constant "whomp whomp" noise heard by everyone within a 10 mile radius of said car.

Automotive accessory installed by very stupid, anti-social, greasy-haired Pachuco boys in their cars. They do this for two reasons. First, it annoys decent people. Second, it will make them deaf as a post, and liberal politicians can offer Pachukes yet another entitlement, free hearing aids paid for by YOU and YOUR taxes.
