QPower 15" Heavy Duty Single Vented Extra Large Vehicle Subwoofer Enclosure Box

Just got my 2 boxes put them in with my 2, 15" 2000rms subs have to repair my back vent panel in my truck now but it's ok f...en love it I'm getting 2 more subs & 2 more boxes WOOOO!!!!!

Well built, fast shipping, affordability. 5 stars!

The speaker box is made of strong particle board that makes it really durable and also makes the sound quality really good. The installation was super easy and should be compatible with most cars!

This box was originally going to be for a kicker to be ran at 2 ohm. It worked pretty good and sounded nice. It was tuned a little high. It was tuned around 35 hertz. I've pushed that sub to the limit and the box has done well. I upgraded to a better model and ran at 2 ohms and it sounds so much better. A bit out of spec for the subwoofer but holding up well so far. Enclosure is built well with great weight. Highly recommend

This durable 15 in fiber wood box with gray covering Is made to thump with the hookup slot installed assembly is very easy. The only thing I dont like is the weight of it this thing is heavy.

I used this when another box broke and installed into my car and it works even better than the other one I had. Really easy to use and will definitely be buying another one for my other car in the future.

Ive had many sub boxes and setups in cars and lemme tell ya this one is solid. Very well made solid and heavy. Good porting and quality connectors not like those old school plastic ones. Pair it with the right speaker and a sub to push it and youll have bass for days!

This box is of great quality is very sturdy and produces great sound. I would give it five stars but it's a bit large for my truck. It's more suitable for a car trunk.

This space for my 15 speaker is solid. This construction is sturdy. It’s attractive and neutral looking for my Jeep. It has inputs to attach my speaker wires. Would recommend!

I installed this with a skar 15 i think it could have a bigger port but still sounds decent had my review sh as kin couldn’t really destroy the lies like it would with a bigger port but it will do the trick

Got this originally for the skar 15 svr d4 to be ran at 2 ohm. It worked pretty good with it sounded nice for the most part but could tell it was tuned a little high. I did the measurements and used a port calculator and says it's tuned around 35 hertz. I've pushed that sub to the limit and the box has done well.I upgraded to the 15 skar evl d4 ran at 2 ohms and omg it sounds so much better. Still out of spec for the subwoofer but is holding up well. By the measurements I took using the box calculator says it's roughly 3.9 f³. Port width is 2 ⁷/¹⁶ port height is 15 ³/¹⁶ and length is 16 ¼. Enclosure is built well from my experience and the weight backs that up. I will be upgrading soon but I do recommend this.

Influenster and QPower sent me this product free for in exchange for my opinion. This subwoofer box will fit a 15 speaker. This subwoofer box is large and heavy one side has a single port that extends the side of the box. The carpet that is glued to it is lined up well. The wood that it is built of is put together with quality and precision. This subwoofer would fit perfectly in the trunk of a car or the back of an suv. Of course if you don’t want any backseat drivers you could always put it back there.

This box is solid as a rock and well made. I put a subwoofer in and a good amp and the bass is incredible and shakes the entire car. The sound quality is great and the port provides the perfect amount of air flow.

 let’s start with the packaging it was placed inside a cardboard box but has no padding or protection for the corners or edges causing it to arrive with a few scrapes and scratches around the outer edges of the box. As for the box itself it does seem well constructed and put together the felt was glued on properly all edges and cuts are done very precisely and has a heavy and sturdy feel to as a speaker box should.The speaker terminal cup is very basic and something I will consider upgrading.The vent hole is ok but I would have liked to see some type of frame surrounding it both mostly just for esthetics. The diameter on the subwoofer cut is accurate and should fit a 15 with no issue.Other than that is a very good looking and well built box. Would recommend.

The Qpower 15 heavy-duty single-vented enclosure box exceeded my expectations. Its sturdy construction ensures durability and the extra-large size enhances bass performance. The vented design not only adds a sleek look but also contributes to optimal sound quality. Whether you're a car audio enthusiast or simply seeking an upgrade this box stands out for its impressive build and ability to deliver rich deep bass. Highly recommended for anyone looking to elevate their in-car audio experience.
