Car stereos are equipment to install in your car and listen to music. Some versions can also read video files, although this is something more specific to automotive DVD and Multimedia Centre.
A car stereo must be installed in the car in the correct way to work perfectly. This installation involves connecting the device to speakers or amplifiers.
Most of the different types of car stereos have amplified outputs of 4x52 watts.
The amplified outputs that output audio from a stereo directly to the speaker are measured in watts PMPO, which stands for Peak Music Power Output.
In the old days, car stereos were products that only worked with AM radio. Then came FM radio editions and an input for K7 tapes (cassette player). In the sequence appeared the CD players.
Nowadays, even the cheapest car stereos work with USB inputs. These inputs are used to connect devices such as USB sticks, mobile phones, iPods, among others that have music files.
