Ryan: This Alpine 10 inch Weather Resistant Subwoofer is for those of you that have a four door 2007 to 2018 JK that are looking for a way to mount a subwoofer in your Jeep that is going to be resistant to any sort of moisture. You leave the top down, it rains, you do some wheeling in wet scenarios, whatever it might be, it's not going to affect your subwoofer and is also going to be mounted in an area that is otherwise unused so it's going to be a nice, clean installation. You're never even going to know that this is there, of course, until you're listening to the radio and you have that bass turned up. This is going to be a pretty easy two out of three wrenches for the installation. Of course with any sort of stereo equipment, there's going to be wiring involved and getting everything hooked up. This is going to be no different, so again we're gonna go two out of three wrenches here but we are gonna show you how to get this installed.There are a lot of different solutions when you're looking to add subwoofers into your vehicle. A more traditional way would be to have a box, usually built from MDF wrapped in carpeting just sitting in that rear cargo space. A downside to that is it takes up a bunch of space. Those things can be very heavy. They are not going to be weather resistant, so again you have the top down and it rains, that can damage your box. It can damage your sub. And this is going to be a much, much better solution than doing it that old-school way. At least in my opinion. This is something that comes with the sub already mounted in the box and the box is designed and molded to fit directly under that passenger seat in your four door JK.Now I mentioned the box and the sub separately because they are essentially separate pieces but they need to be designed to work together. So the sub itself, the size of it and the way that it performs is directly related to the box. So the volume inside the box, whether the box is ported then into the outside or whether it's sealed, all of these things are very, very important to get maximum audio quality. And when you get something like this from a company like Alpine, you have the sub, you have the box, everything's designed to work together, you know you're going to get that really high quality sound out of this which is really what you want.Again, the reason I like this so much is the fact that it does mount directly under that seat and the fact that it's waterproof. So this is IP66 waterproof. It's completely sealed up. Any sort of moisture that might end up in the Jeep is not going to cause any issues with this, all the way down to this weatherproof connector on the end here. This is designed to work with a 500 watt amplifier. That's going to be enough to drive this. This is not going to be something that will be a direct replacement for a factory subwoofer or something that you'll really wanna just bolt in and connect up directly to the head unit. You are going to need to have an amplifier that will run this thing. So again, that's where some of the installation comes in. You will need additional components. You'll need to tie into that factory head unit or an aftermarket head unit if you have one. You'll have to have everything wired. So there is going to be a little bit there as far as the whole installation goes.One other thing to note is that this is designed to fit perfectly underneath the passenger seat of your four door JK if you have the factory carpeting installed. If you don't have the factory carpeting installed, you may need to put a little bit of fabric underneath the subwoofer just to make sure that everything fits as it should. Otherwise, you are going to have a little bit of a fitment issue. But again, if your Jeep is factory, no problem there. This is going to bolt right into place.Now as far as the cost goes from a company like Alpine, a premium company that makes a premium product, you would expect to pay a little bit more. This is gonna come right around that $350 mark. I think that's really fair for what you're going to get here. Again, the quality is here, everything is matched, the box to the sub, completely waterproof. Really clean installation. Not something that's gonna easily be seen or someone's gonna cut open your soft-top and try and get in there and steal your sub. It's tucked away and you're going to get really nice quality out of it. So for all those reasons, I do think this thing is going to be worth the price tag.So as we mentioned before, two out of three wrenches because of the wiring involved here. Let's show you how to get it installed.Man: Tools required for this install. Flathead screwdriver, Philips head, a pushpin removal tool, wire strippers, some side cutters and crimpers. Various extensions for your 3/8 drive, an 18 millimeter socket, a T30 and T45 Torx bit. Optional is an impact.All right, so the first step in getting your Alpine 10 inch subwoofer underneath your passenger seat in your JK is to of course get that passenger seat out of here. So I have an 18 millimeter socket on the end of my impact and I'm going to remove the 2 bolts in the front first. And then you'll see underneath here is our electrical connector for our seatbelts and our airbag sensor and stuff like that. If you have leather and heated seats, you may have another electrical connector. So let's move this tab to the back and disconnect this. Now we're also going to move the seat forward and gain access to our seatbelt down here. Now that is a T45 Torx bit. Put that on the end of my impact and remove that. Now we're gonna move the seat all the way forward and remove our rear bolts. So what we'll do first is remove our floor mat here to gain access to those bolts. And again, these are 18 millimeter. All right, so we're actually gonna remove our headrest to make it a little easier to clear this roll bar. So let's go ahead and press on the tabs, slide that out of the way. And then I'm going to bring the seat back all the way up, grab the seat, rotate it a little bit and then it's free.So one thing we have to do is remove this wiring harness bracket right here. There are going to be two little wiring looms that we need to take a pushpin removal tool and just pop off our wiring harness here. Then we're going to take a Torx bit, a T30, and remove this bracket. Now one thing you can do is take a zip tie and just zip tie this loom to one of these springs at the bottom of your seat. So now I got my zip tie, we're just gonna zip tie our wire loom to the seat spring. And get a pair of our diagonal cutters. Cut off that [inaudible 00:06:25] end.So what we're gonna do now is take the pigtail connector for our subwoofer and attach it to some speaker wire which then we'll attach that to our amp. Let's go ahead and crimp these on. All right, so with the pigtail crimp we can get the subwoofer in and test it out before reinstalling our seat.All right, now we're gonna go ahead and bring our subwoofer in and just place it right there. Best way to tell is you'll see this. We want that to line right up there. And you'll have enough room for your seat mounts. And your connector for the seat. So now we're gonna plug up the tail end of our subwoofer and hook it up to our amp.All right, so let's plug in our connector for the subwoofer. Lock it in place with that. And then we're gonna tuck the wire underneath the center console here all the way around to our amplifier on the driver side. All right, now let's hook up the speaker wire to our amplifier.So as you can see, we are using an Alpine amplifier and I have my power, remote, ground and RCAs hooked up back here. Our last step is to connect our speaker wires. So I already have these loosened up. I'm just gonna slide it underneath that little metal hold-down. And then tighten this into place. And connect the last one here. Now the last step before installing your seat is of course to test out our system.All right, so I have the system on, I have my volume up to 18 and I'm just gonna hit play. It's pretty good. And this is what it sounds like with the subwoofer off. It's really flat.All right, with the sub wired up and tested, now we can install our seat. Let's just make sure that we don't scratch our new subwoofer. We're just gonna place this right on top. And make sure our alignment pin and our connectors are right there. All right, so let's start our hardware in the back here first. So we're gonna go ahead and tighten the bottom bolts first.All right, now the last couple things to do is to of course reattach your seatbelt here with that T45 bolt we took our earlier. All right, now we're gonna put the front bolts in. Gonna start a couple threads. We do not want these going in cross-threaded. Let's go ahead and tighten these down. Then we can make our C-connection. That plug is right at the top here.All right. So as you can see, we have our doors on the Jeep now, and just a heads up, we are using the Alpine ILX 207 which you can find on extremeterrain.com.All right, so this first sound clip is going to be with the subwoofer completely turned off and that's what your Jeep will sound like stock.All right, so this second sound clip is going to be with our subwoofer turned on but our level set at zero.So this next sound clip is going to be with the subwoofer on set to level 10.All right. That sounds pretty good. That's gonna wrap up my install of the Alpine 10 inch Weather Resistant Subwoofer for your Jeep JK. And for all things Wrangler, keep it here at extremeterrain.com.

Extremely happy with this purchase. If the price sits well with you, this custom box is out of the way, keeping your precious storage space available throughout the rest of the Jeep. It sounds great too! Really loud and pushes some air for sitting in such a small space. I recommend turning the unit down as much as possible and it will sit balanced with the rest of the speakers in the Jeep. I haven't had it take on any water, so I can't speak to that.Helpful (2)

This sounds amazing. This 1 speaker has plenty of powerHelpful (6)
What are the changes that make it so it isn't compatible with the 2014 jeep wrangler? is there any products that fit a 10 in sub under the seat of a 2014 jku?
This item should fit 2007-2018 JK models as per Alpine's website.
I would like to double up on this. Could I potentially place one under the passenger seat as well as the driver seat (would driver seat require modification to the enclosure). I understand the need for an aftermarket amplifier. I already have an aftermarket system and speakers. I just need a sub and amp now.
This is designed specifically for the passenger seat and will not fit the driver seat.
Would this work in a 2009 2 door wrangler?
No, this is not compatible with 2-door models.
What amp should be paired with this sub?
This will need a 500 Watt amplifier. The amplifier does not need to match in brand.
Does this need an additional amp or can it just be used with the existing stock system?
This item would require the use of an aftermarket amp.
This is not a Plug-n-Play item and will require an amplifier to run this part.
This weather resistant subwoofer has a compact size and Fits Under Passenger Seat. It is designed to be plug and play therefore adding additional units may require additional wiring or modifications
No, the Alpine 10 in. Weather Resistant Subwoofer is made for the07-18 Jeep Wrangler JK 4 Doors.
