Atrend Bbox Single 10 Inch Subwoofer Sealed Enclosure - Fits 2002 - 2018 Dodge Ram Quad Cab - Carpeted Car Subwoofer Boxes & Enclosures - Subwoofer Box Improves Audio Quality, Sound and Bass - Charcoal

This is an excellent box for a Kicker CompR CWR104 (43CWR104) in a 2013 RAM 1500 Crew Cab. I have the full-bench seat and do not have the fold-out flat floor, so I will be basing my review off of this setup.I'm powering the sub with a Kicker CXA300.1 (43CXA3001) amp that I mounted to the passenger side back wall of the cab and it sounds fantastic. The sub calls for a minimum sealed enclosure size of .8 cu. ft. and this box provides .85 cu. ft., so it is just barely enough but it comes with poly-fil already stapled in to make the sub think it's in a larger box. I chose this passenger-side-only box because I actually use the drivers side compartment pretty frequently, so this box gives me the best of both worlds. It also leaves plenty of room to still use the rear cup holders, which is what I was looking for.I'm very impressed with the quality of the box for the price and have not noticed any air leaks due to a bad seal. The carpet is nicely installed and looks very professional. I had already done the rear-seat-fold-down mod by using spacers to lift the bench seat roughly an inch, but the carpet on the bottom of the seat still rests on the outer ring of the sub (notice in my pictures the outline of the sub in the carpet of the bottom of the seat). The box does come with two carpeted spacers to install on either side of the sub for this reason, but I have ordered a GS Power 10" Bar Grill (also from Amazon) instead because it will provide much more protection than the included spacers. The terminal cup is kind of located in a bad spot though, because there is not much space behind it once it is screwed in. The product description says it is best to solder the speaker wire to the inside of the terminal tabs, and I would definitely agree with that. I tried using quick disconnects, but they pulled out fairly easily because of the angle I had to bend the tabs for everything to fit once screwed in. I soldered the wires to the tabs instead for a much more reliable connection.Overall, I am highly satisfied with this box, especially for the affordable price versus other pre-made boxes or building a DIY fiberglass enclosure. I highly recommend it for 4th Gen (2009-2017) RAM Crew Cab and Quad Cab pickups.Bonus: Using Amazon Prime's free 2 day shipping method, the box was delivered in only 23 hours after being shipped. An incredible shipping speed rate for a product of this size and weight!

Looks nice, but not sealed. Slightly pushing the sub gives you lots of audible leaks on the far side of the box. Due to the only 1" or so clearance there you can't even seal them yourself. Well maybe if I strip off the carpet and take the box apart. But why not just make your own at that point.It was dirt cheap, but the old saying if something seems to good to be true it probably is comes into play here. Disappointed.EDIT: I've been using this for 10 months or so now and it is fantastic. True it's not sealed as well as it should be, but it's not having much effect on the bass. It's minor and as I've heard before the 'flawless' seal isn't that big of a deal (not like it has holes in it or anything). My old school NIB Polk DB10 (the 90's USA made stuff) fit perfectly and absolutely pounds in the 40-60hz range that I use it in (CDT Audio 6x9 CF "Subs" in doors pick up the 60-110 range). I'm sending 300w at 4ohms to the sub. Really great, tight bass. It also looks great. What did I learn? Before bitching about something I should try it and see how well it works, and this works great. For those having issues I recommend tuning a bit or making sure the amp/sub etc is all correctly set. This is an impressive dirt cheap box. Also, Amazon says it won't fit my 2014 Ram. It fits perfectly! For those with newer body style Rams don't be afraid to buy.

Looks beautiful fits beautifully but lacks the edge I’m accustomed to. For the money it’s perfect. Entry level works great but, does not perform like a Skar custom box. I do recommend this box though which produces good sound, well built and can’t beat for the money. It can be overloaded through wattage. Not recommended for anything over 600-800watt RMS actual power to the speaker. 600 rms Skar fit great but the 800 RMS VS Skar needed a spacer as you see in the pict.

Nice little, well made, good priced single sub box for under the back seat of 4th gen Rams. I put it in my 2015 1500 crew and it can fit many normal sized subs. A Fosgate p2d10 fits & even a p3d10 fits barely if you remove the rubber magnet cover. You can pry it off with your fingers carefully one side at a time in a couple minutes.Don't think you have to go with a shallow sub & give up some deeper range bass. One 10 in this box in my Ram is plenty & not ridiculous. You could add a spacer ring to gain 3/4 of an inch if needed but this box gives you about 6" mount depth. Other small Ram under seat boxes are taller but this one has a little more space from the sub touching the bottom of the back seat. Can't even tell it's there til the radio comes on! No seat spacers needed like I read many people are doing.

Got it on sale for roughly $40 so for that price it's definitely worth five stars. Paired it with a 10" shallow mount Skar (brace is large so I had to use a rotary tool to enlarge the opening a little bit). Added the four bar grill to ensure the bottom of the rear seat wouldn't contact the speaker. Box fits like a glove and provides exceptional bass considering the size of the box. Sending 500 watts to the sub so I'll see how it holds up. So far, no complaints.
