  • Nice box for the price!
Box sounds nice and punchy very tight bass and the low frequency is great. Perfect for the trunk of a classic car with a modern retrosounds deck.

  • Great packaging so it arrives safe
Nice box that is well made and pre wired. Small in size so it fits anywhere

  • A GREAT BOX FOR A PRE-FAB. CAN'T GO WRONG. THE BLACK CARPET LOOKS GREAT. APOCALYPSE
THIS BOX IS A GREAT SOUNDING BOX WITH THE RIGHT SUBWOOFER. YOU CAN'T HAVE A SET OF CHEAP SUBWOOFERS. I PUT A PAIR OF DEAF BONCE APOCALYPSE 8 INCH BASS SUBWOOFERS. THEY WERE 200 DOLLARS EACH ON AMAZON. THOSE SUBS WERE SO HEAVY, SHIPPING WOULD BE MORE THAN THE SUBWOOFERS AND THE CT SOUNDS PORTED ENCLOSEURE. THESE SUBS MOVE A LOT OF AIR AND THEY SOUND LIKE A COUPLE 12 INCH KICKER COMPS. I DIDN'T SAY 15'S. THEY MAKE THERE OWN SPECIAL SOUND. CAN'T GO WRONG. TWO JL AUDIO 15W1 SVC. PPI A1200 AMP. ... show more

  • The quality is great and the fabric is fantastic
Fit in my truck perfect as this fit just right between my seats and the kerf port is nice too

  • Nice Box
I purchased this box because it was already to spec with the 8” meso CT has. The build quality seems good and the carpet is decent. I think for the money to get 3/4” MDF and push terminals is great and definitely worth the current cost ($140)

  • Box is bigger than the loaded enclosure box
Awesome prefab box

  • Great box
Great box for my car, puts out just enough bass that it doesn’t distort. The box is put together well, and the price is good for what you get.

  • Bass is good
Bass is good but cabinet radiates pretty good at 200 hz. Slightly disappointed
