I thought long and hard about whether to get the 10-inch or 12-inch, and I went with the 12-inch. This compact subwoofer amazes me every day—it delivers incredibly deep bass that you can adjust to your liking, and it barely takes up any space in the trunk, even though I have a sedan. It’s a very sturdy, high-quality product. I recommend it to anyone who loves great bass but doesn’t want it to take up space in their trunk.

I was about to have a couple subs installed at a custom shop, but decided to do this one myself. Sounds awesome to me. Plenty of bass for 2025 Sierra Denali with Bose. Install was easy but I’m also pretty handy. For the money, I highly recommend this setup.

Great value, very compact . Have it connected with the kicker line output converter for my 2023 ridgeline . It’s got clean tight bass in an all in one package .

Fits good. Seat is a little high but a few washers under the seat base will level it out. Sounds great. Used lci2 to connect along with a PAC L.O.C. Pro Advanced Audio Integration T-Harness. Made it easy plug and play was done in 2 hrs.

It does not produce as much bass as I had hope. It just does not move enough air in the small box. I do understand that, but was hoping for more bass.

I put this is in a 2019 Sequoia and it fits perfect into the cargo area with the 3rd row up. Hits hard and produces great bass with the OEM speakers. The down firing form factor works great in the cargo area and you can also place stuff on top of it. Very happy with this powered sub!

Love it. Had zero issues with it. I stack my tools on it when I need to, no issues at all.

I had a 24 speaker stereo back in the early 90s in a camaro. Rattle the other cars at the stop light setup. But its been over 20 years since I had a stereo like that. I put this unit (500w version) in a stock 4th gen Acura MDX Advance. Here is my opinion - Oh its so easy to only have a few wires - power, ground, control knob, input from stock subwoofer and two knobs to adjust. That's it. Set the gain on the high side and then use the remote knob to dial in the bass based on the song being played. I don't mind fiddling with the gain knob in between songs. When I want to hear the lyrics I keep it turned down. Then for some songs I want to rattle the interior like back in the day and turn that knob up. The fact that this thing can regulate heat inside the enclosure is baffling to me. I had so many heat issues back in the day. You lose the adjustabilty of a seperate amp + crossover with a bunch of adjustability to dial in your system if you are after perfection. But if you already have a car with a great sound system like I do but just wanted more oomph out of the bass. You cannot go wrong with this setup. More than enough to give you a headache or damage your hearing.
