Worth the extra cost when comparing the competition. Great Sound.
Model: 51PTRTP12
I should have started with this one. I did not want to spend the money so I bought other brands downfiring including the 12 inch Orion and was not happy. This is a clear not distorting sub giving that little boost that my sound system was needing. It was a hard pill to swallow paying this much but it is a very good quality sound. I like it.

Can’t beat it for the price
Model: 51PTRTP12
Fit perfectly in the back of my Tahoe behind the third row. Sounds great for an all in one unit. Price was competitive and shipping was fast. It’s not gonna rattle your neighbors windows when you drive by but adds low end response to the factory bose speakers I already had.

Plenty of bass for a normal situation
Model: 51PTRTP12
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.

This thing is a BEAST
Model: 51PTRTP12
This thing is a beast. If anyone is saying not loud enough then they do not have it set up correctly. It is plenty loud. I have one in my 22 Subaru Crostrek and could not be happier.

Still slaps just need to turn the bass knob up a little higher.
Model: 51PTRTP12
Overall this is an awesome package, 12in sub with a built in amp in a very good manageable size. I replaced an older 10in kicker solo L7in a ported enclosure, nothing wrong with is still hitting strong but I just thought I would upgrade to a 12in. I like the downward firing aspect as it clears up some space in the trunk of my car. Only thing is I wish it would hit a little harder but I guess that’s the sacrifice that I made in order to regain some of my trunk space. Don’t get me wrong it’s still hits hard and sounds great but I think my old 10 hit just a little harder. All things considered I would say that I am substantially satisfied with my purchase.

Great product for my vw Jetta sportwagen
Model: 51PTRTP12
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.

Should you pull the trigger?
Model: 51PTRTP12
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.

Great sound in a compact design
Model: 51PTRTP12
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!
