Quality

Ease Of Installation

Constructed with a substantial weight for durability.

I liked that this box was a perfect fit, I also liked that you can keep your jack and jack stand in its factory location.

Perfect subwoofer box for a 2022 Silverado

walmart.com

[This review was collected as part of a promotion.] Fits perfect under the seat of my 2007 crew cab Silverado, had to double face it with two sheets of 3/4 mdf to fit the 8's i wanted too. 
Very well made box except for the little plastic terminals but they seem easy to replace.  So awesome .

Fit perfectly

influenster.com

[This review was collected as part of a promotion.] I am going to be honest! I am reviewing the 8 inch Dual Port Subwoofer for GMC and Chevy Crew Cab and I just dont have the knowledge of this type of thing to be able to compare it against, so I am passing the phone over to my husband who does. 
Nice system subwoofer box here. I installed it in my truck for the weekend and was shocked at how good the sound was. Seems like good quality too like it will hold up for some years. I would buy this again.

My husband says they are pretty good!

[This review was collected as part of a promotion.] This is an amazing product. It fits perfectly with my GMC big truck. I definitely recommend if you have this care because it has amazing sound quality. Better than everything else i have tried. Buy it because it is amazing.

Amazing sound quality

[This review was collected as part of a promotion.] Sturdy material and the piece is well done. It fits perfectly on my GMC 2010 truck. The installation was easy we put it together with speakers at home.

Sturdy material

[This review was collected as part of a promotion.] This box fits perfect under the seat of my customers 2017 Chevy Silverado crew cab. Good sound and easy to install I recommend it…………………………………….

Good sound

[This review was collected as part of a promotion.] This is the sturdiest subwoofer box we have ever had. My husband has a Chevrolet truck and is full of speakers but this one just won't work for him as his subwoofers do not fit in this. He needs 4 holes but he also needs larger holes. We expected them to fit but they do not. We would love to give this five stars but because of the fit we can not. Again, this is the best made speaker box we've ever seen. There are also a few scratches on the side where the speakers are but it would not even hurt the sound of the subwoofers.

Made great

[This review was collected as part of a promotion.] The box is great for hard hitting bass. It will not play higher frequency bass notes very well so you will need to have some good mid and high range speakers to complement the overall sound quality.  I had a couple of my screws strip the whole when mounting the sub. Overall I am very satisfied with the sound quality of this box. I have it installed in my 2022 Silverado crew cab with 2 CT 8" Meso subs (800watts RMS each sub) and a 3000 watts hifonics amp and I can't believe how hard this setup hits.

Great bass

[This review was collected as part of a promotion.] Not really sure what this is for. I was under the impression that this came with speakers.  I also am not sure where exactly I would put this.  In my trunk?  Anyway I don't think it's necessary

Ummmm

the ship him was excellent but the way it was shipped was very poor no protection around the Box whatsoever got damage during shipping
