Best Bass Pounding Box EVER!!
I have the Hifonics Brutus OLM1612 sub enclosed in this bad boy box and it pounds like no other. Its a very solid box and is true to the dimensions and box volume...I would HIGHLY suggest buying this box to my friends, family or strangers (plus Sonic has the best shipping, was super fast). If you want an all around great looking, great sounding and great performing box...then just click.."+ Add to Cart" button and let the pounding begin!!

Good prefab box
Box does look clean and nicely built. Put my american bass 12" xfl in it and it pounds! Had to make cut out a lil bigger for my sub to fit but not a big deal recommended for anyone who can't build their own

12'' Ported Box
I recenly purchased this box along with the power acoustiq mofo 122x. I tried the mofo in a box i had for two kicker comp 12's, and it didnt sound up to par. When i put it in this box, its like it got 10x louder. And it hits the lows perfect like i wanted. Cant really use my rearview or sideview mirrors.
The box is well built and sturdy. I drive a 99 blazer 2 door btw.

awesome box for the money
I have my Alpine Type R in this and it pounds! I had it in a .8cu ft box I got at bestbuy and it was too small and choked it out, the whole car vibrates now and hits lower notes better, gets those real low ones i love :) only thing I don't like is the port is on the side so its kind of against the trunk, but its far back enough to work so if you have a small car like a civic you just need to measure =]

Destroyed
I got this box for my 12" Fi BTL and it's a great box while it lasted. Now my box smacks wood and sounds horrible i had to put 5 screws to keep it from making that sound. this box is perfect unless you have something pushing to much power like my sub

booom!
This box kicks hard! It makes my JL Audio 12w3v3 hit so harder than it did before in my old 1.3 cu ft ported box. I love it. I would definitely recommend this box and website to anybody. Thanks Sonic

Great Buy! Custom Enclosures 12" Round Hole, Long Rear Slot Ported Enclosure
Bought a big enclosure in order for it to fit exactly in my trunk and wouldn't move and slam around because of my driving :p. I really love it, bass kicks great even of how big it is. It is ported so it helped out from the size. Great Buy! Great quality! Recommend!

Good Deal
Used this box for a Fi Bl 12 and it slammed hard. The tuning frequency is around 41-42 hz so the lows arent very loud and the sound quality isnt always the best but its good for a prefab box. Good box if you dont mind that high of a tuning.
