The Jensen JW6A is a powered 6-inch subwoofer built to slide under a seat in cars and trucks where a boxed sub won't fit. Its Class D amp is rated at 600 watts peak, with a variable low-pass crossover from 50 to 150 Hz, a 45 Hz bass boost and a gain range from 200 mV to 12 V. It takes high-level speaker wires or low-level RCA inputs, so it works with a factory head unit or an aftermarket one, and a wired remote knob lets you trim bass from the driver's seat. It suits drivers who want more low end without giving up cargo space; against rival underseat subs it is a low-cost, slim option, but a 6-inch driver in a shallow box moves far less air than an 8- or 10-inch sub and won't deliver window-shaking output.

Owners rate it well overall and most praise the space it saves and the bass it adds to a stock system. Complaints center on output that is modest for the rating and on setup quirks.
