  • OMG....OMG...OMFG...I TAPPED OUT!
Product Packaging: Standard Packaging
This is a large box, so far i only listened to about 2 songs on it, and it definitly slams hard. I will need to re adjust my amp gains because its actually violently, ball shakingly, ear poppin, TROLLINGLY loud. I literally cut it off when approaching my street, it is just bangin on an offensive level, which is good! Granted im running a higher level spl budget build i suppose.... but heres what im running. 2 american bass elite 12's wired to 1 ohm load on a soundigital 2k evo ll pushing 2600 rms at 14.4 volts, powered by a 2nd agm78 battery, keeping voltage between 13.6-14.3 while listening at moderate volume,running 0 gauge OFC welding cables and 3 seperate 300 amp fuses, and an ampro 5 volt preamp from the headunit to the sub amp for a clean signal. This box is all my subs needed and is the 3rd and my final box at this point. The box is huge with 4.5 cubic feet of airspace, which is what my subs needed. Prior to this box i had a custom 2.5 cubic inch aeroport box tuned 30 hz made specifically for my charger...and it bumped, it even trolled a bit in traffic... but my lows were all port noise because my subs were not breathing as they should.....the box was too small for my specific subs. Now a typical 400 rms sub would of been ok with the box, but each of my subs are 1200rms rated......and by putting them in this qbomb, i litterally had to cut the shxt down....and i am a basshead, been in the game for over 10 years and understand the science behind sound systems and impedences. With that being said, it takes alot for me to tap out,and this box did it....all i could do while bumping 2 chains "countin", was grin ear to ear screaming OMG with pure adreniline running for fear of hearing damage. I had to back off before the song ended, and this was volume level 30 out of 39. ...my go to level with the prior box i had. I am going to have to turn my amp gains down.....i highly recommend this bix, the ONLY setbacks so far for me is it will not hit those LOW LOWS...30 hz and under very (violently) loud, but will hit them decently....and the inside terminals are pretty sketch, i actually bent one on accident, but just used the 2nd tetminals on the other side instead i took away 1 sturdyness star for that....but Other than that, this box is just nastey. ... show more

  • This box is a monster! Needs modification tho.....
Product Packaging: Standard Packaging
First off, I love the box. Please read thru this review to understand why I modified it and why I think it's better that way. The materials used to build this box seem to be of great quality. It's very solid and sturdy. And with the thick spray coating covering the entire outside this gives it longevity as it will protect it from humidity and wet weather, which in my experience has destroyed enclosures over time. All that being said, I really like this box. What I don't like is the giant port holes. As you see in my photos I sealed off each port hole and the bass quality increased dramatically. It changed the entire sound, and made my subwoofers produce much deeper bass notes that it just couldn't achieve in an unsealed box NowIf they were built as they should be, like a high end quality box, then they would be awesome! But they're not. They're just big holes in the box, they literally serve zero purpose. It's almost like an unfinished box. Yes it may still sound decent. Yes it may slam in most car trunks, that is because CAr trunks act as sealed boxes. But still, it isn't built correctly. And it negatively impacts the bass. Subwoofers cannot achieve those really deep low bass lines in a box that is unsealed. They need back pressure, which also makes them slam harder as well. In a high end enclosure with vent ports, they are built much more intricately. Before the opening, along the cave of the port hole, there would be kind of like a maze of woodwalls. Very tightly close to each other. This makes it so the back pressure created by the bumping subwoofer has a hard time getting thru the port, which in turn creates more back pressure to make the woofer slam harder while still letting are thru and giving it that ported sound. You can see diagrams and such to better understand what I mean, with a quick Google search. But anyway, again I love this box. Ive always gone after bigger sealed boxes because of the power, and the low bass noted you can achieve. And after I sealed the ports on this box, it is perfect for me. I'm really enjoying this box. Super glad that I got it! ... show more
