I bought a slightly-used ski boat in July. No stereo but otherwise a very nice boat. No problem--rather than install a conventional receiver as on the old boat I instead bought a Bluetooth speaker setup from a company called "Herdio" which used 4" dual-cone flush-mount speakers. Which works great; Bluetooth connects to my phone in a few seconds and the sound is clear and loud enough for a running ski boat. Of course, no bass, since the speakers are mounted in part of the fiberglass interior and thus the bass from the rear of the speakers can get out and cancel the bass from the front. So I bought this woofer from Sound Storm to fill in. Very surprised by the quality. The thing was inexpensive, surprisingly heavy, built like a tank, and sounds great. The beefy metal case gets warm during use, so I assume it's part of the heat sink. The typical situation is to mount it under a front seat in a car, but in my case it is mounted on an unseen carpeted area under the boat's dashboard. The combo sounds really impressive. I have many albums on my phone and of course I can also tap into numerous streaming music sources on the Internet. One little negative: there are two ways to wire this woofer into your system, high and low-level. Low level connects via RCA plugs to a system that has low level outputs via RCA jacks. The second option is to use the actual speaker feeds, which is a much larger signal. On the unit I received, the high level connection didn't work. But the low level inputs did, and I discovered that if I turned the volume adjustment (via screwdriver) all the way down, the signal was low enough to not overload the unit. I could have returned the unit for another, but since the alternative input method worked just fine, no need. All in all, a very nice woofer at an amazing price. Clean output adjustable for frequency band, bass boost, and level. And (usually) a choice of high or low-level inputs.

I used this to compliment the speakers in my Jeep, I am pleasantly surprised with the sound, for its size its impressive. Its not gonna rattle mirrors, but it makes a terrible stereo sound high end when set up right. Been installed about 2 months so far and holding up well.

For the price I can not complain, but if your looking for a sub that pushes some loud bass, this Sub is not it. It helps with sound QUALITY, but overall loudness and bass amplification it does little to nothing.

Exactly how others felt I feel the same. Does a good job for what I need it for - to fill out the sound system in my 80 series Land Cruiser. Fit barely under the passenger seat. Vibrates the seat pretty heavily when I turn it all the way up makes for a fun surprise to anyone rolling with me.

If you're looking for something to fill in the lows , then this will work. Doesn't come close to what I was expecting. But for the price point, it serves it purpose . Don't expect slamming bass. Almost sounds like a single boxed 6x9 . I went ahead and purchased a boxed Skar 6.5" and CT 700 monoblock amp. This didn't have enough kick for my taste. But it did bring in the lows I was missing for a more enjoyable sound. For 80 bucks I can't complain too much.

This is THE replacement for those over priced way too fragile and woefully overrated Dayton audio bass shakers. No trying to mix or match amplifiers wishing and trying to get more out of the wimpy things while stressing that your going to blow then which you probably will (Hey, It's not your fault.). Throw all that stuff out and strap I or 2 of these guys to your seat and thank me later.

I had an amp and sub separate and it was difficult where I had to install it in my vehicle. This fit right under my seat and is WAY easier on install than my previous setup. For me it gives more bass than I need at times but you can install the bass controller under your dash and just turn it up or down when you want. I am very happy with this purchase. Only thing I noticed that I'm not crazy about is if I turn down the volume of the music the bass stays stronger than the music so I have to turn down the bass control. Not a big deal but wish the bass went down with the volume. Still very happy.

Prior to this i had just tried a round 8” ‘wheel of bass’ powered sub that had a super peaky response around ~80hz that couldnt be flattened even with pretty good EQ settings in head unit, so it sort of sounded like it just played one note all the time because everything off peak was so much lower in volume. In contrast, THIS unit gives nice even response so ends up being much more ‘musical’. Gives nice volume. Remote knob gives pretty decent resolution vs some others ive seen that did almost nothing except go from 100 to 0 all the way at one end. Overall, really solid pick, no complaints!
