QPower Single 12 Inch Sub Enclosure, Universal Downfire/Behind Seat Speaker Box

Installed in truck for a better sound experience

I put this box in the king tour pack of my Harley davidson screaming eagle cvo Electra Electra darksided. Holds a DS18 12" DUAL 2 OHM SUB

It leaks air out of the connection part got 2 of them and the both do the same. It's not a sealed box at all. Complete waste of time and money. And it smells horrible. It looks like a nice box but as u look closely the coating is falling off and low quality.

Fits comfortably in the trunk of a vw cabriolet with plenty of room to spare and sounds great.

This box fit perfectly under the rear seat of my 2015 F150 SuperCrew. However, there were a few issues. First I noticed the sprayed on bedliner coating was not sprayed on evenly and looks thicker in some spots. Next, the wire terminal leaked a lot of air, so I had to put a bead of silicone sealant all around it. That worked, but then I noticed air leaking around to speaker itself. I think this was due to the rough texture of the bedliner coating causing the sub to not get a good seal when screwed down. So, I had to put a bead of silicone around that, too, then screwed the sub back down. Now it sounds fine, like a sealed box should!

I got this to add fill to my work truck because my highs were very bright it seemed small to me when I got it but the price was more than reasonable! Once I mounted my shallow mount sub the sound was fantastic from this little sealed enclosure and it for easily under the back seat of my truck. Couldn’t be happier with this purchase!

Its actually great in the passenger floorboard for a front shallow mount sub. The coating is tough enough i let passengers put their feet on it. I added some fluorescent lights for show at night. They don't come with the box or does the Focal sub. Just make sure your Measurment's on your sub will allow it to fit, Even the shallow mount Focal was about as deep as i could mount in the box.Overall i like this one so well im contemplating buying the 12” version.Before mounting i did pull the speaker terminal out due to reviews and silicone glued it in. Then i replaced the screws and put a silicone glue bead around the terminal on the outside. Never has leaked like this.If your sub isn't sealing its either too deep or a MM or two too big and needs hand fitting into the enclosure. If your sub is too deep you can make a gasket around the outer mounting edge to raise the sub up a bit. But not much tho as your sub may hit the floor if it has enough excursion.

It does not feel light or flimsy.It does not come with internal wires ready to connect to your sub.They didn't make it with cheap tiny guage wires, they left it up to you what guage wire to use.I was expecting the bed liner paint and some texture.What doesn't show well in the pictures is that the paint has the traction grit in it.This works well for a carpeted surface to reduce sliding around if you don't anchor it down with brackets.
