I have is box for my 2 Alpine Type X Subs. so far im not on a good foot with se. One on my subs had a blown voice coil upon arrival. How that can happen, i have no idea. none the less, the box front (which is silver) is a cheap spray paint that comes off VERY easy. also the terminals are very weak. tryin to attack them to the 1 speaker bent very easily. im kinda nervous about the sound quality since so far i feel is cheaply made. ill try to post a better comment if the box doesn't fall apart when the bass slams.

Built my own box and ran into some difficulties. I guess that happens when you have someone else use the jog saw.... Anyways, I'm running two Alpine SWR 1243Ds and an Alpine PDX M-12 and they sound crazy good. Plus the box I had made was honestly too big. This box gives my the correct cubic feet that I needed. Just ordered my 0 gauge monster cable and about to order a new battery too. Thanks to this box I have a great set up. Thanks Sonic for helping me make the right choice.

Its not quite big enough for the subs I have but it still makes them sound great. Its built with quality, and will last me a lifetime

This box seems to be build really well its really heavy ...it hits pretty good im running to RF P3..great value cant get anything like this for under 100 and it comes in like 5 colors to match your interior...
