There are 18 speakers. One is a subwoofer. The Challenger's speaker system was designed by Chrysler's sound team. It includes 16 speakers, one subwoofer, and two tweeters. The drivers are mounted in four locations: inside the front wheel wells, under the floorboards behind the rear wheels, underneath the trunk, and inside the rear bumper. A crossover network selects which frequencies each driver will reproduce. Volume and tone controls are located on the front of the car near the headrests. A small display on the center console shows information about the audio system. In addition to being stylish, the Challenger's speaker system provides excellent sound quality. It is available in several trim levels, so you should be able to find one with speaker packages that meet your needs.
