    Nothing special

    Posted by Shawn Robertson on May 23, 2024

    With a $500 MSRP and a $300 price on sale I was expecting more than just a run of the mill prefab. The box came with a dent on one the face boards that hold the subwoofer panels and it is pretty obvious it was just sprayed over and wasn't a shipping problem. There are multiple runs in the coating and the coating isn't thick enough to hide the seams. The sub cutouts are slightly misaligned and are at least a 1/4" wider than spec's which is an issue I'll have to work around for my subs. The sub mounting are is nice and thick but unfortunately it is attached in the box instead of over the supporting walls. The logo looks cool but unfortunately it is upside down if you have your speakers pointing up. A speaker lead pre-wired in the box would have been nice. I haven't had a chance to hear it yet because I have to buy additional parts to have a good secure mounting surface. Hopefully it makes my subs sound better than the $200 skar box it is replacing and I can come back and say it was all worth it but I'm pretty disappointed now

    Best Bang For Your Buck!

    Posted by Marco Perez on Mar 19, 2024

    This enclosure is amzing & well built for the price...My favorite features is the double baffle & kerf port. I highly recommend for a entry to mid level sub duo.

    Very Nice PreFab

    Posted by Brandon Thelen on Feb 06, 2024

    First of all the box is awesome quality and mine arrived undamaged unlike quite a few other reviews. It's A little small on the cubic feet. It was too small for my TXX-BDC4S they got way louder in my Q-bomb box with a huge port. So I don't think any heavy or large subs that require air space would sound "loud" in this box. BUT i ended up putting my Girls P3s in this box and put in her 2020 Malibu on 800 watts and let me tell you this thing BEATS! I'm very impressed her windshield flexes. It's double baffled and has bracing. Awesome box for a trunk for sure. I upgraded to a custom built 2.5 per side box with 2 vfx 12s on an RP4500 in my jeep and it's loud, and these P3s in this box still impress the hell outta me every time I take her car. Only improvement would be a wider port and larger box. They have a bigger triple baffle box but it was way to expensive for me.

    This is going to be that review that’ll probably get denied but let me save y’all money from buying this I couldn’t be more disappointed and pissed off Re writing an update on this box since i barley purchased this prefab back in march 2023, where do I even start lmao this box didn’t even last a year nor past 5 months. The box is still in its shape no physical damage but rattles like crazy even at very low volume. I thought my subs were blown but the sound is coming from this box and sounds like absolute shit. Not even the prefab I had before this one did that lol. NO I didn’t put an overweight sub than the required specifications for this box, I had 2 American bass XFLs and this box couldn’t even handle them decent weight subwoofers like this box falsely advertised . also I had to over sand the cut outs to make my subs fit. NO THEY DONT FIT MOST SUBS‼️the design is nice but the quality was never there. 100% regret wasting my money on this box now I have a custom enclosure being built to replace this shit. Im done buying from D4S y’all overhype your products too much when the quality isn’t there?

    Disappointed, not even my cheapest 12s fit

    Posted by Shane on Mar 26, 2023

    Always been a fan of JP and will continue to be, but was very let down when none....and I mean none of any of the subs I own fit in this box. Cheap American bass hd12d4's Set of older p3 Rockfords Set of alpine type r's Even a.set of power acoustics I had lying around.... Going to have to buy a router and pray I don't screw it up....once again I'm not taking jabs at jp. Decent dude that does good service, I think I just got the runt of the litter unfortunately

    Box is great

    Posted by Graves on Mar 14, 2023

    Came in with some damage, understandable since it is made in vietnam. 4.5 stars because the cutout is slightly too small to fit the deaf bonce sa272. Had to sand it down to get a smooth install. Other than that is great. Plays loud down to around 25hz. Best value for a good box hands down

    The box quality and design is 10/10 Only reason I’m putting ⭐️⭐️⭐️⭐️ is because the box came in with a slight damage on the top right corner. Not too worried but still these box’s aren’t cheap... I’m putting 2 American Bass XFL 1244s in this thing, excited to see how much of a difference this one makes compared to my last one

    Kerf port two 12s box

    Posted by Sam Hood on Feb 20, 2023

    Overall build quality is definitely solid. My only complaint is the finish. the bedliner finish, while nice to look at, is an extremely thin layer,it don't take much to rub through it for it to start peeling.

    Minor damage

    Posted by Edgar Morales on Feb 11, 2023

    Overall the box is amazing, it is worth your money, sounds great. The only problem I had was that the corner was damaged during shipping but other then that it’s great

    Best premade box ive ever incountered.

    Posted by Dasfriek on Dec 16, 2022

    Heavy birch. Heck heavy everything. Double front baffle. Great engraving on top, all very well evenly coated. I have two Avatar 12” 3000rms subs going into it with no worries of the box not holding up. One negative, it only has one speaker hook-up that looks like a SMD made connector, just a bit thinner. I planned on this and ill be adding a SMD m8 speaker connector to the opposite side so i have more options in how i wire the subs. The size has the most CF of any premade box. Its rather on the expensive side, But with this you get every penny well spent.
