Speakers are parts of the sound system that turns electric current into sound. Different frequencies of sound can be produced by using individual speakers, such as the tweeters for high-end frequencies, mid-ranges for middle frequencies, woofers for low frequencies, and subwoofers for ultra-low frequencies. There are also coaxial speakers, triaxial speakers, which combine more than one driver in a single case.

Other speakers are driven by a head-unit and still some needs to be powered by an amplifier. The replacement speakers are mostly having better quality than the stock units. Price sometimes is a good indicator of a speaker with the good quality, however beautiful sound can be achieved by putting matching set of components together. The 2001 Chevy Cavalier has an infinity midrange speaker. Speakers create a pretty good environment when driving specially during a long drive. Owners of Chevy Cavalier who love music very much will surely choose the best quality of speakers for a more enjoyable ride.
