Soundstream USB-8DL

Today's active powered subwoofers bring big bass to small spaces that a typical subwoofer wouldn't fit. USB active subwoofers are made from a die-cast powder coated aluminum enclosure w/ an integrated grill, protecting the subwoofer & amplifier from unintentional damage. Traditional pre-amp features like low-pass crossover, 45Hz bass boost, and a signal phase switch bring dynamic sound to life. RCA Line-in & speaker-level inputs with signal sensing turn-on provide various options to integrate USB into your vehicle's audio system. A wired remote control is included, allowing volume adjustment from the driver's seat.
