Pyramid Car Audio prides itself as being the most affordable solution to car audio. The founders of Pyramid over two and a half decades ago developed a notion of how to bring affordable audio products to the US market. With this constant vision in mind, it took only a few short years before Pyramid was considered the worldwide leader of affordable audio products. The PW877X subwoofer is designed to crank out earth shaking bass. Its small 8" size makes it easy to install, but don't let its size fool you. With a 400 watt power handling and Kapton voice coil this sub is sure to impress.
