The incredible Junsun subwoofer system delivers incredible output and infrasonic bass extension typically only possible from much larger systems. The key to this performance lies in the precise tuning of its Junsun subwoofer driver into an efficient tunnel system with a slot-ported design. The high power handling and high excursion subwoofer converts your amplifier's power into bass you can feel. What’s most impressive is all that bass comes to you in a minimal amount of space: taking up less of your valuable vehicle storage space. | Junsun | | 10"Slim Under-Seat Powered Car/Truck Subwoofer Sub+Amp Kit Deep Bass 800W Remote Control NEW US | Black | Best Buy
