The RetroSound® SUB8100 is a powerful 8-inch amplified subwoofer system designed to fill in the low frequencies usually missing from your classic vehicle's sound system. This compact subwoofer measures just 2 ¾ inches tall, so it is ideal for installation beneath your seats or behind the seats of a pick-up. A built-in 100 watt Class D digital amplifier provides plenty of power, and the continuously variable crossover lets you fine tune your bass. A remote level control allows you to control your bass volume from your seats.
