When we set out to make the Underseat compact powered sub, we wanted to make a subwoofer that could fit almost anywhere and still deliver the performance that made Soundstream famous. At just 3″ tall, this should surely fit under numerous seats and in storage areas. The controlling, built-in 150-watt RMS amplifier delivers strong bass that’ll add intensity and thump to any system.
