Great bang for the buck and the compact size saves a lot of space
Style: 12" QBOMB
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! ... show more

Does what it's supposed to but quality control is lacking
Style: 12" QBOMB
It is what it is and the price was decent. Box is sturdy and didn't notice any leaks or major defects, however the quality control on a couple things are lacking. When it arrived the coating on the box was flaking off and shedding a good amount. Probably wasn't cured long enough or prep work was subpar. Even with that the coating hasn't come off so much the bare wood is showing, so it's holding up good enough. Installed in my wife's Wrangler and needed something waterproof. Other issue is the terminals didn't fit completely in the hole and stuck out a good amount. Guessing they didn't clean out the coating before they tried jamming it in. Was a simple fix but lazy craftsmanship. All in all it was worth the money and was perfect for what we needed. ... show more

Super low quality product
Style: 12" QBOMB
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 certain F250’s very well

Seems to be built well and fits perfectly between the rear captains chairs in my 2005 F250.

Good fit
Style: 12" QBOMB
These will work under the back seat of a Nissan Titan crew cab. Only other option was to have them custom made which would have easily costed double. Well constructed of sturdy materials. 12 inch woofers fit right in like a glove and sound great enclosed in this box.

It's not bad!!
Style: 12" QBOMB
Not bad for the price. There were some minor issues with the bedliner finish having chipped on a corner and some junk left inside under the coating. Nothing catastrophic so I put a shallow mount 12 from a known brand that rhymes with shmioneer and it's pretty loud! Great match for their "A series" subwoofer! The 12" box is just a hair too tall for my back seat to latch on the ole F tree fitty but the dogs don't seem to mind. I can't speak on the durability of the box yet but, it seems like it should be fine for the everyday abuse. It shipped with one of the roughest carriers and only had a tiny chip on the corner. Go ahead and buy the Q-bomb and get a little bass into your life! ... show more
