I’ve got 2 Skar 12s and a Gothic 12 (got another matching Skar 12 coming) and this box seems to hold up well. Let’s see how long it lasts with all this bass.

Got these JBL for $30 each on flash sale. Usually $95, had a single in a ported box for a few months. I grabbed another next sale,and a double sealed box and now this box at 3x12 is freaking perfect.DO NOT put 2500 watt subwoofers in this box and fully power them properly ( Skar EVL and Skar 4k amp, it will definitely rattle apart quickly. Maybe if you threw some screws in it and resealed it.....na, build your box for grown folk stuff like that. You would have to fiberglass inside and out for that powerBut if you hit up Walmart for some Gothics and a Power acoustic 2500. This would be great!!

Update: 2-13-2025, the send box I ordered last year has stood the test of time. I updated the star rating for such.Update: 2-22-2024, 2nd order. This box has gaps in the front part of the box, in each separate chamber. The gap is so wide, I could the depth of the wood for the joining pieces . Also, there was barely any seal on the inside... I'll try to seal it with some Modpodge.The measurement is 40" wide. I have a 2014 Impreza base model. The box was just the right amount of space. Any more and this would have been useless due to the arm for the trunk. I soldered the wires onto the terminals for my subs I will soon be getting. The pictures speak for themselves. I am happy with the sound as well. I only use sealed enclosures because I like my bass tight. This will be my first subwoofer setup with more than two 12's. Definitely worth the money. .... I see some complaints about them not being sealed, Mine came with it caulked. I guess they maybe reading the reviews. Just keep an eye out, and lets keep updated on the quality with picture reviews.) (Review as of 2 18 2020)

no caulk or sealant in box. expect to recaulk as soon as you get the box because it will not work right at all if you don't. got two of these and they seem to be decently built at an ok price but they were not sealed.

I was going to build my own box but when I saw how great the price was on these I changed my mind. It would have costed me more to buid them and alot of hassle. Shipping was super fast and boxes are well built! I def. recommend!
