I tried a cheap Amazon box for a while. Sounded OK, but just couldn't get that deep low bass I like. Then, I tried a supossedly better "tall" sealed box, from a place in Florida. Still wasn't happy. I decided to pull the trigger on the Fox Box and WOW!!!! I'm just blown away by the difference. What a difference a good enclosure makes! It's only been a week, but I'm now enjoying that DEEP DEEP bass I like. I'm using 2 CT Sounds Ozone 12" in there @ 1 ohm final, on an Apline 1200w and man, let me tell you, it sounds great! Box itself is very well built and sturdy.
One small gripe, but it could be my situation, because I installed sound deadener material all througout the rear, but the 1" lift kit was just not enough. In the listing it says "1.25" seat lift kit is included and is required for proper fit", but I measured them and they were 1". The seats were kind of smashing down on it, so I installed an additional 1/2" with even longer bolts and everything is great now. So, just be ready to fabricate a little, if you have to.
Overall though, this is THE box you want if you have a crew cab Ram. I wish I would have gotten this one, right from the rip. Buy once, cry once! Well worth the $$$.
