Atrend Bbox Single 12 Inch Subwoofer Sealed Enclosure - Fits 2002-2018 Dodge Ram Quad Cab - Carpeted Charcoal Subwoofer Box

Great fit in 2020 ram warlock (classic). Single 12 under passenger rear seat. Had to remove fold flat floor but at same time unbolted seat and did folding seat mod so worked out well. YouTube that it's genius. Box sounds good for the size. Could have been a bit bigger for a snug fit. Added some screws to strengthen box as I'm told they are just glue ups.

I installed this enclosure in a 2016 Dodge Ram 2500 Crew Cab Laramie Power Wagon. I was worried about having to use seat spacers to use this box but that was not the case. You DO NOT need seat spacers in a 4th Gen Ram Quad/Crew cab. You can verify this by checking the box dimensions, 32.5: wide, 13.5" deep, and 2.5" tall. This box fit very neatly under the passenger seat. I did have to remove my factory fold out storage deck on the passenger side and will most likely put my driver side back in to make it that much harder for anyone trying to get at the amplifier. My interior is piano black and this matches well but not perfectly. The pictures don't show the coloring as well as I had hoped. The box is slightly lighter but is a good compliment to the interior.I installed a Kicker CompRT 12" 2 ohm DVC sub and it fit perfectly in this box with no trimming or shaving the interior. I soldered the speaker wires to the terminal connections on the box as crimp connections are kinda iffy and there is not a lot of room once you install the terminal back into the box. You will need to pull it and seal this area to make it air tight so have a small tube of silicone ready when you are installing this. The speaker is wired to 1 ohm.I am driving this sub with a Kicker CX400.1 amplifier which came factory rated for 525 Watts RMS at 1 Ohm which is perfect for this sub. I placed this under the driver side rear seat. Pay attention to where the amplifier sits as the bottom of the seat will make contact with the amp when seated. I miscalculated the measurement and the edge of the bottom makes slight contact with the amplifier. My only real concern is that the amp will not dissipate heat in that area as well now. Other than that the amplifier fits nicely and i have good access to the adjustments panel.Next, I installed the Kicker GR120 speaker grill as the sub would be muted from the bottom of the seat and potentially be damaged when a bigger person sits in that seat. The grill is plastic so I will have to wait and see if a sturdier metal grill is needed.I used a Rockford Fosgate RFI2SW to grab the door speakers from the rear to get the HI signal. I tried the factory subwoofer speaker connections but they are not full range and gave low performance on the sub. You will need to pull the B pillar covers off to access those rear door speakers. The speaker wires were twisted pairs with the following colors:LRSPKR + GRY/LTGRNLRSPKR - GRY/DKGRNRRSPKR + DKGRN/LTGRNRRSPKR - DKGRN/GRYI found another set of twisted wires in the bundle and pulled the door panel off to verify these were correct. I believe these other wires were to the LED's in the door trim but don't quote me on that as I just glanced to be sure I had the correct speaker wires.The Kicker CX400.1 does not require an LOC (Line output Converter) and uses DC Offset for the rmote turn on so you don't need to run a separate wire. This is part of the new FIT+ technology they have in the amps. Just double check that your amp has the same tech in it but just about any new Kicker amp will have FIT in it. This made for a VERY clean install. One thing to note is that I did solder the door speaker wires to the high level RCA input plugs and put a bit of heat shrink on them for protection. If you pull the door harness plug while you are in the B pillar it will give you a bit more range of motion on the wires as they are very tight. The soldered joint should keep me from having to pull the B pillars again in case of a failed connection.I ran the Kicker CXARC bass control back to the front and used some 3M double sided tape to place it under the dash cubby and give it a clean factory look. I'm not a fan of drilling and wanted the interior to look as factory as possible. Also, I recessed it a bit to keep prying eyes from detecting it from a window. No sense in having someone smash your window and try to steal your system. The enclosure is not bolted down as I wanted to be able to remove it easily.Now for the sound. This speaker/sub combination is absolutely amazing! It's not gonna win a competition but the bass is way from this sub and enclosure is more than I was hoping for. It absolutely hits hard and carries very nicely from the factory radio which is the uConnect 8.4" with the 9 speaker Alpine system. the headunit has very minimal equalizer controls (honestly Dodge needs to step it up) and only has bass.mid/treble controls. I adjusted most of the bass out of it and let the Kicker do its work alone. Highs are not as crisp as I would want so those dash speakers will have to go at some point. The front and rear door speakers do a nice job carrying their weight and overall this system really hits. I listen to everything from Upchurch to Bhad Bhabie and they all sound amazing. Definitely get the bass remote or you will notice clipping from one style of music to the next and for those days you just want to chill in a quieter ride. Kicker recommends low to medium volume with low gain for at least two hours a day for the first two weeks to get it broke in. This will allow the woofer to last a lot longer.Overall, this is a great product and really good combo! Do your research and buy stuff that will last!

Great but I rolled my truck off the highway before it got here so I couldn’t use it haha

Works well and sounds really good I get compliments and my teenagers love this setup. This box is non-ported so the sound is tighter and doesn't extend as much a a ported one. Does not interfere with the seat folding operation in my 2012 Ram crew cab . The inside of the box needed to be trimmed inside a little for the Skar Audio shallow mount speaker to fit in it but that is expected when buying a generic enclosure and putting another manufacturer's speaker in it. A multi-max tool makes it fit in 20 minutes. I recommend a grill to protect the speaker cone from the bench since it will touch the bottom of the seat when the bench is down.

Kind of a cheap made box. Wish there was a little more air space but it is what it is
