  • Sturdy
Not to much power good little addition doesn’t move on carpet either
Reviewed in the United States on April 8, 2025 by Charles Stein

  • You WILL need to buy more cables
The sub came in fairly quickly so pretty decent shipping timing, less than a week. Opened the box & found the high level input speaker wires that are only a couple feet long, the *gain remote* to put to the dash & some screws for the gain remote. No power wire, RCA cables, remote wire, or ground wire, and the high level speaker wires they include probably won’t reach past your trunk if you need them to. They have another set of this sub that includes pretty much all the wires necessary for under $100, but this specific listing doesn’t include them. Also, if you drive a newer Kia Forte with no rear factory sub & speakers in the doors, GOOD LUCK! Installation is a pain in the behind since my specific backseats don’t fold down. I haven’t gotten it to work yet since my car is a pain to get wired to, but I won’t knock them for my car’s issues. Will update if/when I get it working on how the sound quality is. 12/19/22. Edit 12/22/22: Got it working right, mis-wired on my end & some help from some buddies got it going, for the size of it this thing packs a punch, the trunk is practically sealed from the cabin & the sub has no problems at all rattling my mirrors & the backseats are LOUD. not sure you can get better for the price especially since it’s not even broken in yet, this is all from first day use. played all genres of music on it, with rock & metal it adds that extra depth to the bass & drums that makes it sound more alive & with rap the 808s pound to really make it a trunk shaker. not sure why some people said it wasn’t very powerful, as long as it’s tuned right it’ll definitely surprise you with how good it bumps. ... show more

  • You can't beat this for the money
I just installed this into the back of a small SUV and it sounds great. I wanted a small subwoofer to add some bass without taking up a bunch of space, and this speaker is perfect. I couldn't do one of the under-seat subs, so I had to get an enclosure and I do not regret my purchase. It has plenty of bass for most people and really completes a factory system. I have been really impressed, especially for the cost. ... show more

  • Pretty sweet
Wife wanted a little more bass 🔊 in the soul. So we tried this little blue monster out. What a joy to install and enjoy. Even just jumpering off the rear speaker wires this is way loud enough to make the factory stereo pound and shake the rear view mirror. 😳 Would definitely buy again.

  • Blew after 5 months with average to aggressive use
Good all in one sub for the price but the speaker blew after about 5 months with the gain set very low. I replaced the woofer with a Kicker CWCS84 which is a more reputable brand but isn't as loud as the rockville woofer but it's a lot cleaner tho I have to set the gain over more than half. The pic is of an additional amp mounted on top of the box. (Ignore the wiring, I haven't cleaned it up yet). This setup is good for a little umph to the low end ... show more

  • I personally love it. Jeep Wrangler '02
I was looking for something to throw in the back of my jeep behind the bench seat that would fit, take up the least amount of cargo space possible, and deliver much punchier and more full bass through my sound system. When I saw this product I thought it would be perfect for the price point and would help me skip a few steps with setting up/matching a speaker and amp. I was a little concerned about the dimensions but this cabinet seriously fit PERFECTLY behind my bench seat and leaves about 75% of my rear cargo space free. The sub itself and amp deliver more than enough bass for my personal taste and I actually keep it turned down a bit most of the time. I'm extremely happy with my purchase. ... show more

It impressed my friends.

  • Awesome sound.
Never installed a sub, this made it super easy. Quick tip: when you install this into your aftermarket stereo, make sure u set the eq to flat and then adjust your settings from the sub woofer. You’ll be amazed with the sound and clarity you’ll get.
