      Video Review & Installation

      Merideth: Hey, guys. So, today we're checking out the JL Audio Stealthbox in black fitting all 2020 and newer Gladiator JTs. So, if you are a fan of bass when it comes to your music and you're looking for a substantial upgrade when it comes to sound, this option by JL Audio will be a great choice to check out. Now, the stealthbox will include 2 10-inch subwoofers that will give you a deeper and louder bass tone without muddling your music and affecting its clarity. Not to mention they will be stored inside of this stealthbox as it says in the name that will hide underneath your rear seat keeping it hidden and out of the way and also will have a custom fit that won't require you to modify your Gladiator unlike some other sub upgrades will. Now, again, this will have those 2 10-inch subs that are already installed in the stealthbox here. It will have a power handling of 600 watt RMS and are wired for 2 ohm mono.I would like to mention that this will require an amp in order to power the speakers. And depending on your setup, it will vary on what kind of amp you need. If you are interested in this choice, I would just keep that in mind. Nonetheless, when powered up, you're gonna get great sound quality that isn't over the top like some other larger options. As it'll also have a high-quality housing to the stealthbox, this will be made of a quality fiberglass material which will have a lot of rigidity and is great considering the location of being under the seat. And this will also have a black carbon material that surrounds the entirety of the exterior of this stealthbox here and it will blend incredibly well with the interior of your Gladiator, making it virtually invisible. Now, you will have to delete the underseat storage box but you will be able to retain your factory Gladiator's hardware storage. So, that is a little bit of a bonus there.Now, with a premium setup like this, also comes a premium price point which is very expected and this is gonna sit at roughly $1,400. Now when taking a look at some other choices in the audio category, you'll see a number of different options between speakers and subs. Now, what makes this option stand out is the housing for the subs and how well it fits with the interior and also the fact that you're getting 2 large 10-inch subs. Now, other options, even one with a housing very similar to this may have a smaller sub at 8 inches instead of the 10 that you see here. Not to mention, most upgrades come with just the subs themselves and don't have as straightforward as an install as this choice will.Nonetheless, if you are looking for some premium sound and you're looking for a full kit to work very well inside of your Gladiator, then this is gonna be a great choice. Now, install will be pretty straightforward at a one of three wrenches on the difficulty meter, taking you about an hour or so to get this into your truck. Now, again, like I mentioned, you will need an amp specifically for your setup in order to get this and whatever else is included in your setup powered up. So, again, just keep that in mind when it comes to install. One of our installers here is gonna walk you through how to get this into your truck step by step. That wraps it up for my review. Let's go ahead and get into the install.Man: Tools used for today's install, an E14 socket, a 10 and 15-millimeter socket, a cordless ratchet or a cordless impact. What's up guys? I'm gonna be going over the installation process for your stealthbox on your Jeep Gladiator. I do wanna point out there though, that this JL Audio does not come with a wiring kit, so this video will strictly be just for installing the box. Let's get started. All right, guys, so the first step we're gonna lift our seats up exposing the storage compartment and we're gonna have 4 10-millimeter bolts. We're gonna go ahead and remove those now with our cordless ratchet. Got our 10-millimeter socket. All right. Once you have all 4 10-millimeter bolts, this compartment should just slide right out and onto the next step. All right. So, now we're gonna go to the hardtop hardware compartment. I'm just gonna open that up, pull out the foam inserts, and you're gonna see 2 10-millimeter bolts here and here. Got our ratchet, 10-millimeter socket, and we're gonna go ahead and remove those now.There's gonna be a little plastic retainer clip in the center. Pop it off just like that. Grab the rest of your stuff, and we can put this off to the side somewhere safe. All right. So, for this step, we're gonna have to remove the seat bolts. They are E torx 14s. You're gonna have one here and one here. We're gonna go ahead and remove that now with my E14 socket. We just wanna place that somewhere safe for now. We're gonna get this one now. And same thing, just put this off somewhere to the side. All right. So, for this next step, we're gonna mount our brackets to our sub. With our supplied hardware, we're gonna come around. It's got our 15-millimeter socket. And the orientation should be just like this. We're gonna start it by hand with our supplied hardware. It should be a bolt, a lock washer, and a flat washer. Just get them started. Again, these should be not cranked down. Same thing on the other side.All right. And that takes care of this part for mounting the brackets. Now we can move over to the vehicle. All right. Now, so that we have our subwoofer in the car, before we mount it, this would be a good time to connect any kind of wiring harness. Obviously, you're gonna need some kind of power supply or wiring to your subwoofer. This is where you would do that now. We're just demonstrating how to mount it. Now, our bracket should be loose and we're gonna just lift and kind of align it with those holes we took out from the seat. Same thing with this. Lift and lay over. We're gonna get our seat bolts that we took out the E torx. And we're gonna start those by hand. Get our socket here. Again, this is an E13. I'm just gonna run this down. I'm not gonna go crazy tight. I'm gonna come in and do the other side.All right. So, we got our E14 bolt. We're gonna go ahead and install this on our passenger side by hand. And then we're gonna get our E14 socket and just run it down so it's snug, not tight. All right. Once you get that tight or actually rather snug, you can adjust this accordingly if you need to at all. And we're gonna switch to our 15-millimeter socket. And we're gonna go ahead and tighten those bracket bolts that we initially didn't wanna tighten down. Now, we got our 15-millimeter socket and we're gonna go ahead and tighten these bracket bolts down now. We're gonna switch our sockets. We're gonna go to our E14 to the seat bolt. And you're gonna wanna torque this down, obviously, to manufacturer specifications because it is a seat. You're gonna repeat this same process on the other side.So, that's gonna wrap up this review and install of the JL Audio Stealthbox in black fitting your 2020 to current Gladiator JTs. Thanks for watching and for all things Gladiator, keep it right here at
