Conclusion: Fits great, looks great, sounds great!!! I am using two 10" Kicker CompVR and it sounds incredible. I would suggest extracting the included poly-fil if you decide to get full sized subs like the CompVR. Make sure the subs are sealed with silicone because the fit is really tight and a bit difficult to seal, otherwise you will get some air leakage. Unlike any other box for DODGE RAM. BUY IT!
Conclusion: This thing is awesome! You would think the small amp that this comes with would be minimal at best, but it rocks the cab of my truck! If you are looking for a speaker box or a sound upgrade that is simple to install, you have to be crazy not to purchase this one! By the way, customer service was perfect!!
Conclusion: I would recommend this box. I put one in my 2004 dodge quad cab. I used Alpine SWR-1043 D because of the power handling, and small depth requirement which is 6". Although i had to make spacer rings out of 3/4" particle board with a jig saw.I used screws, and silicone to seal them. I also put some 3/4" wood with carpet on it to prevent vibration under the back of the box to level it out.
