Great option for a budget setup
Good option to add to a budget or stock car audio setup. Won't impress anyone but it fills in that missing thump and low end. Do note that this doesn't come with any of the required wiring, so make sure to pick up a wiring kit (I got some cheapo kit here on amazon for like $12, just make sure its at least 10 gauge) and I wired directly into the rear speaker wire. Out of the box it's set to a base non-tuned setting so won't sound good at all - you NEED to tune and adjust the settings on both the sub and your head unit. Read the manual, it explains how to set the gain. I think I ended up somewhere with the gain set to 3/4, bass boost almost near max, and the high pass filter a half or turn up from middle (this is important if you're regular speakers don't produce a lot of bass). I also turned down my head units "bass boost" setting from +3 to +1 as the regular speakers don't need to try and fill in bass anymore and let them shine more in their minds and highs.

Sounds Terrific
I got this for my husband. He has a an extended cab toyota tocoma. It lends a perfect amount of base in that amount of space. It sounds really great. He is very happy.

Good subwoofer until you can afford something better.
It’s fine. Gets quite warm during normal function and it doesn’t sound quite as good as my other 12” 1200 watt Rockville Sub. Acoustics overall are lacking. Affordable is great though and works great as a “hold me over” subwoofer until you can afford something better

Fits under the driver seat in my PT Cruiser
Good sound. The first one I bought gave out after a couple of years, but it looks like a factory defect. Still, at the current price, it beats anything else I have found. When people get in my car the scan the back area and are amazed at the sound. Using with a Kenwood in dash media player. Great sound with no loss of cargo space.
