The DC Audio M3 6.5″ subwoofer is designed to work in extremely small box volumes “0.3 cubic feet each ported” and give you the maximum amount of output. These little monsters have you covered on the low frequency spectrum. As newer cars and trucks with less and less space are being designed and released, a demand for a smaller subwoofer with high output is needed to supply the demand for “Bass in a small space” application.
