This fits perfectly under the passenger seat of my '07 Liftback. Kenwood claims 150 Watts and response down to 35 Hz, but these specs must be taken with a grain of salt. This has a 6.5" active driver and a 6.5" passive radiator, which gives more output than a single active driver and allows for lower frequency response from a smaller box, while not inducing sonic problems that ported cabinets can have. I got this for US$165 delivered from an eBay Buy-it-Now.
My goal was to relieve some of the stress from the main speakers by adding a powered subwoofer that did not take up any significant space in this tiny car. I didn't want to replace anything else (although I may upgrade the front door speakers some day), and I wanted to keep the cost reasonable. I work with audio all day, so I had to keep my sonic expectations realistic here.
The stock head unit has no pre-outs, so an active crossover (while ideal) was not an option. Speaker in and out to the sub, along with power and the included remote, was the whole installation (I paid a local installer US$65 to do this - well worth it).
After a little experimentation with setting the polarity (mis-named phase on the remote), crossover point (around 80 Hz with the bass on the head unit at -3), and level (I like plenty of clean bass!), this is a great addition. I hear about an octave of extra, clean bass. Instruments down below 60 Hz are much tighter - the stock setup was distorting somewhat when played loud before I added the subwoofer.
