This box is big but extremely efficient. Due to its design it can make any sub hit pretty hard with very modest amount of power. I've swapped both a G5 and W3v2 into this box and they are both extremely loud. I also powered the subs swapping with 500 watt monoblock and 150 watts bridged amps Again it hit equally hard with 150 watts of power! I'm convinced that you can put any inexpensive sub in this box and power with a very modest amount of power with amazing results. I would recommend this box highly to anyone trying to get the most bang for the buck and doesn't mind sacrificing trunk space.
However if you have 500 watts or more power, you may want to get a sealed box for better sound quality. I have 2 Diamond 10's in a simple sealed box which sounds cleaner. Sealed boxes are not nearly as efficient. They require more power but sound significantly cleaner, yet take less space.

I received this box yesterday. I installed the Lighting Audio Strike S4.10.4 Woofer in it. This box is SICK. I only have 190 watts pushing this 300RMS woofer and my entire truck just shakes.

I recently purchased this item. I found the item to be of good quality and made the completion of my car audio system a breeze. The sound is good. I used a Blaupunkt 10" woofer and added some batting material inside the box. I would recommend this box primarily for the price.

This box is made to boom if your looking to get the max sound out of your woofer than get one of these. I put it in my car and got what i wanted nice strong deep bass.
