Summary: Very good compact sub. Good bass response. Very compact. Easy install. I have installed this in a GMC truck under the rear seat and it fills the cab with decent bass to help the 6 speakers in the doors have a bit more punch. The controller is a bit strange in that it is hard wired with a bulky cable, and has a blue LED built in that may or may not match your interior. In my case it fit perfectly into a factory dash pocket with a slight mod to run the cable.
Summary: I have to say, I'm pretty impressed. I have 2014 Passat, and it just fit perfectly under my passenger seat. I have an Alpine 45wx4ch Universal Power Pack installed, and the bass coming out of my 6.5 inch Rockford Fosgate Primes was just too puny. This was the perfect compliment. One thing to note--I originally installed this using the speaker outputs coming directly out of the head unit, and could barely hear it. I thought since all it needed was a signal, I'd be fine.
Summary: I installed this inside the cabin, in the passenger footwell, of a mercedes C300. The bass is enhanced, but it's not a real subwoofer. On the plus side, it's the smallest sub available and draws little power with an in line 10 amp fuse. The unit can also be uninstalled easily if you want yo sell the car stock.
Summary: Wow. I've used other compacy powered subwoofers before but this one is tops. It's by far the smallest one. It doesn't have the mirror shaking thump.but you hear it and know it's there. The highest output setting is too much for mu taste.Super easy to install, super easy to setup. If you're looking for something that is just a little more than just rounding out the music, I would highly suggest this one. 2013 Ford F-150 Supercrew.
Summary: It does exactly what you think it will do. I had pretty terrible stock speakers and no sub. I replaced my receiver, all my speakers, and the lack of bass just killed me. As long as you don't expect this to blow your doors off and you are just using this as a filler then it is wonderful. I love the remote it comes with, I find myself fiddling with it all the time. It is installed under my passenger seat and there were no issues with the install.
Summary: My head unit is a Naka-NA780. I recommend using a low level out. From experience I can say that the hi-outs don't offer the same level of control or low hz sensitivity. Heck using high level outs is akin to using buckshot when a .22 will not only be more cost effective but more efficient and efficiency is what we're talking about here folks. This powered sub provides an abundance of usable bass across a wide range of frequency.
Summary: At times I love this enclosure. The controls allow me to adjust the bass levels for the song, which is a lot of fun. It reminds me of the "Loudness" buttons you used to see on older stereos that boosted bass response for lower listening levels. I find that while bass guitar lines jump out at you, the bass drums are somewhat limited at times. The sound improvement overall is fantastic though, and I am hearing details in songs that I have otherwise missed over the decades.
Summary: I was very disappointed in this subwoofer. I'm using it a 2006 silverado extended cab and listen to mainly country and classic rock. I didn't think I'd need anything too powerful because I was just looking for something to fill in the bass for the type of music I listen to. I was going to send it back but after spending $50 plus dollars to install it I don't think I'm going to because I'd have to pay to have another sub installed and it's not worth my time and money at...
Summary: Excellent sub. Easy to install and very small; about the size of a 12-disc CD changer. I mounted under the passenger side of a 1999 Camry front seat. Filled in the missing bass frequency. I was going to build a 5th or 6th order bandpass using 6.5 inch sub driver but when I added up all the parts, it was close to $180. Figured it was better to leave it to the professional. Now this is nothing like a JL 10 inch sub but then you lose part of the trunk.
Summary: I own a 2003 Mazda Miata that came stock with Bose speakers. They sound great but I wanted a bit more bass. Unfortunately this product doesn't deliver much. So if that's what you're looking for I suggest you look elsewhere. But for me, this is all I can fit and will most likely keep it. Sound quality is good and the install was relatively easy. Not bad for the money.
