Loud car stereos are stereos producing very loud music, usually 140 decibels and above. Though loud car stereos are a rage among the younger generation, these are potentially harmful. Prolonged listening to music over 85 decibels can cause permanent noise-induced hearing loss. Loud music in cars can also make you unaware of your surroundings and lead to serious accidents.

Car stereo sound is enhanced with the help of speakers, subwoofers and amplifiers that are available in a number of popular models. Most of the recognized car stereo companies manufacture and sell loud car stereos of various frequency ranges and intensity parameters. Their advertisements and promotion tactics have resulted in a number of young males opting for loud car stereo systems. Loud car stereos have become something trendy among the present generation of youngsters.

Reputed companies such as Blaupunkt, Sony, and Kenwood manufacture car stereo multi-channel amplifiers. These are designed to raise the car stereo system to new levels of loudness with minimal distortion. These can drive a subwoofer or a simple system at even higher volumes. Loud car stereos can be quite expensive, with some stereos costing up to $8000.
