Want killer bass without sacrificing your car's legroom? Check out the AINAVI 10-inch active under-seat subwoofer. This thing is a powerhouse packed into a slim design – only 3.2 inches tall, so it slides right under most front seats. It’s got a built-in amp pushing 800 watts max (220W RMS), with a MOSFET power supply for clean, efficient sound. Tune it your way with the adjustable low-pass filter (50-250Hz), bass boost, and gain control. Hook it up using the high- or low-level inputs – the wiring kit and adapter are included. Oh, and it looks as cool as it sounds: a multi-color LED light ring around the sub adds a slick glow you can control with the remote or a smartphone app. Dimensions are 13.5” x 10.2” x 3.2”, and it weighs about 8 lbs. We recommend professional installation for safety and best results. Comes with a 1-year warranty and support. Crank up your tunes and feel the difference!
