Revel in better reverbs, bass, and treble with car amplifiers purchased on Overstock.com. Boost your bass through two-channel, 50-watt speakers that go in your trunk, along the doors, in your ceiling, or on the front panel of your vehicle. Rock out with intense, 100-watt amps that elevate the higher frequencies. Go overboard with a compact system that uses more than 100 watts of audio power added to your system. Adjust each speaker individually at the point of installation or from your car's console to get that perfect balance for your favorite genre of music. Just mount these compact speakers in place of the original system to enjoy better sounds compared to your car's factory-installed products. Pyle, Lanzar, and Pyramid have lush selections here. These three manufacturers produce consistent, high-end products that enhance or replace your car's existing speaker system.
