QPower Single 12-Inch Downfire or Behind-Seat Speaker Box, Features 0.75 Cubic Feet of Airspace, Compatible with Most GMC, Chevrolet, and Ford Trucks

No complaints what so ever at a $40 10” sub box that fit my needs perfectly. Well built & looks good. Hard a hard time finding the right terminator spades as none of mine were all to skinny for the spade at the connections. So, I just soldered my 16ga white to the terminals and then 2 layers of shrink tubing. They never fall of thats for sure.

I have limited space in my vehicle to install a large subwoofer so I purchased a low profile 12-inch subwoofer (Infinity ref1200S) and it fits this enclosure perfectly. After some basic testing, it sounds good. I'm not after massive, window shattering bass, just a little more than typical sized car speakers can produce. This works out great for me and at a great price.

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!

I like the quality and how it sounds

Not sure off I got a knock off box or not, but the 12" shallow mount box is for was not big enough for my JL Audio 12TW3 sub. I double checked to make sure I ordered the right biopic and I did. The box it came in had the info for the 12" sub as well. I measured the diameter of the hole in the box and it was 11". Not sure what happened but I'm sending it back!

Perfect fit works great deep and loud

It's ok but I'm kind of upset. The size in the specs shows 0.53 cu/ft of internal volume. That's wrong. It's 0.46. That may not seem like much of a difference but when you're trying to spec out a box this small, .07 cu/ft is a huge difference. That's 13% smaller than advertised. Most subwoofer manufacturers don't want the enclosure volume going more than ±10% of their recommendation. Just be aware of that. You'll need to add some batting material inside to help "fool" the woofer into thinking the enclosure is larger.

Just as described, so far so good
