Pardon the dust in the picture! I know some people say that's its not very powerful, I thought that too when I first hooked it up to my factory radio in my jeep run off of a LOC and then tried high input.. neither were very good for me. So I decided to replace my head unit and factory infinity speakers. Hooked it back up, plugged it into the aftermarket stereo.. and wow! now im sure you could find more power and better speakers somewhere else.. but for under 200 dollars? Its plenty enough for me.. does better than keep up with the bass in my JKU.. its an attention whore. Ive only had it installed properly for a week now. So hoping it will last a long time. This thing does have a very good sound quality, like I said.. for under 200 dollars im extremely happy.. that's a tenth of the price I paid for the rest of my system. It was very easy to install. Took me less than an hour to run the wires and Mount the unit with some homemade brackets because I do a lot of offroading so I wanted it secured. I thought it was going to be bigger, im sooooo happy the box it small and dont take up much room in the back. Very pleased with that. I decided to go with rockvilles 4 gauge wire kit, Altho I had to trip just a small amount of wire off for the positive and neg to load the wires in.the back of the box. Was no problem! Bottom line: so far im very pleased with the size, quality and BOOM. Super easy install in my Jeep (Granted ive had my jeep in a million pieces a million times so I know every wire and all the places it run through the firewall.) But all cars are pretty much the same. Im sure there are videos on YouTube to help you out. I was not paid or didnt get anything from this review. Just a simple and honest review. If it craps out at any time I WILL update this. One last thing: the single 12 box is only like 6 inches shorter than this double 12" sub box. For those of you who cant make up your mind on the extra space. 6 inches wasn't much difference for me.. ( that's what she said). Good luck and boom on jeepers

WOW, this Subwoofer is INSANE, sounds so clean. I installed in an 11 Sonata, and worked very well when plugged into high input. VERY, VERY, Powerful. Would recommend.

i am 19, wanted some nice speakers and bought these.. the sound was great for about a month and then it started making a horrible rattling sound, only to find out they are made from plastic.. the vibrations from the speaker shattered the hard plastic brace on the inside of the speakers and made it sound horrible.. i repeat DO NOT BUY THESE… go spend 100$ at walmart for kicker speakers, they are better and are made from metal

I had these in my Toyota Tundra, and it was way more than enough. Sounded like a multi thousand dollar setup. My son wanted some in his Honda pilot and they didn’t pack quite the punch. Great power, look is clean especially with a built in amp. Easy to use and has install everything is very straight forward. The only functional issue I could see is fitment, it’s not very big but it is a box so in trucks it may be difficult. Great value for the money great sound.

This product was a little bit of a headache at first because I bought the used version since it was $100 less and they ended up sending me one that only has one working subwoofer so i was disappointed but after talking with Keisha for a few days and after it was received by their returns department they were nice enough to send me a new one. Customer service was great, shipping was quick but the only thing I was disappointed with was being sent a broken item besides that the subwoofer itself fits nice in the back trunk of my 2017 Kia Forte and now I have lots of more space compared to having a huge one 15 inch subwoofer kicker. The built in amp is also nice, that saves me even more space.

I bought this to try to fit under my seat on my 2017 F150 it does not fit not with the seat fully down to make matters worse the actual connections are on the bottom of the amp and sub not on the side like other models it's just a pretty bad design I don't know where you would fit this other than standing upright or maybe in a truck bed which nobody does

I have had nothing but good results with this speaker amp. It has a great sound and it really bumps. I had it installed because I don't know how to do all of that stuff but it sounded just like a full system. Definitely recommend this combo.
