Kicker Car Audio - The Company Kicker has been in the audio game since as early as 1973, and it was in 1980 that Kicker switched all their focus on producing high-quality car audio equipment. With industry-leading designs and continual developments to improve, Kicker has become well known for its ground-shaking subwoofers, audio crossovers and the amplifiers in charge of running them all. Solo-Baric and Santoprene surround are two of many technologies Kicker have implemented into their designs. Along with previous technologies, this helps to create a high performance and superior bass, which in return exceeds anything else in its class.
