    Box is well built and looks nice but the terminal plug allows for air to escape. Since it is a sealed box it causes alot of noise/whistle so the plug had to be removed and sealed with silicone. Other than that it is a very nice down firing box for a standard size subwoofer. For the price. The black finish does have some dull areas that look like they have been worn or rubbed as if something has been sat on it for an extended period of time.

    Doesn't have the "Q Bomb" logo on top.

    This box is very well designed. I have had numerous boxes through the years in the many trucks I've owned.This one is by far the best crafted, and priced in the market today. The under coating finish is second to none.. carpet boxes always look shitty after a few thousand miles in a day cab truck. I look forward to see how this one holds up. The unfortunate side is, my name begins with "Q" I was dissatisfied that it wasn't embossed with the manufacturer logo on top like its pictured. Q Bomb...

  • Very little clearance!!

    Used in back seat floor of a 02 F150 with a Rockford Fosgate T1 Slim 12. Very little clearance, actual had to add about 2 inch wooden legs on all 4 corners to clear the speaker safely. Wouldn't expect the any speaker to clear it unless you have a completely flat surface! My truck had a slight hump which made a bit more difficult. With a few modifications and speaker grill protector, I was able to use it. Sounds okay, don't expect too much due to little air space even with polyfill.

  • Solid box

    Loaded a JL Audio 12tw3 and commenced to bang. I'm liking the bed liner coating, very durable but added a rubber gasket between the box and sub when loading to gain an air tight seal. Also had to caulk around the terminal. Overall a great deal

  • Good Value, Hole cutout is too big

    Good value for the money. Was going to make my own but worked well for my boat project. Other than the mentioned hole being cut a little too big, could not get the sub to seal without using some weather stripping.

  • Great, Well built box.

    Got leaking around push terminals but silicone fixed that. Paired it with a Kicker 43CWR12 and it pounds. Wouldn’t fit under the seat of my Tundra DC though.
