Review & Install Video
Hey, everybody, I'm Justin with americanmuscle.com, and in this video, I'm gonna be taking a closer look at the Raxiom by JL Subwoofer Upgrade Kit for all 2015 and newer Fastback Mustangs, equipped with a factory subwoofer. Now, in my detailed breakdown, I plan on talking about why prospective buyers might wanna upgrade their factory sub in their Mustang with a 12-inch option here from JL. We'll talk about what's included with the kit along with some of the specs, and then finally, we'll cover a brief, little overview of the installation process. I'm gonna go solid two out of three wrenches here on the difficulty meter due to the light wiring of course, but we will have some more detail on that later on.
Now, the JL kit that we have in this video, again, will appeal to those 2015 and newer Fastback owners who have the Shaker Pro Audio System with the 12 speakers in the factory subwoofer, but feel like the factory sub just tends to fall a little short in regards to overall output or quality. Now, by going with this turnkey system here from JL, you're gonna be replacing that 8-inch factory subwoofer and the 100 watt factory amplifier with one of JL's 12-inch subwoofers and corresponding 500 watt amps. So, in turn, you're gonna be getting a much bigger bass response overall, a lower frequency range, and just a lot more thump, while still essentially maintaining the same amount of usable space in the trunk. And with all that said, I do feel like the biggest appeal with this kit here from Raxiom and JL is the fact that it is a turnkey system, essentially ready to rock and roll right out of the box.
Now, could you piece together a different system using different components maybe save a couple of bucks? Sure, but this is a convenience factor, guys, you're getting everything you need from soup to nuts right out of the package. Yes, you gonna be spending a little bit more money for that, but you are getting quality components in return, and again, this thing is ready to install the moment you unbox it. So, Ford has been using their patented Shaker system for pretty much as long as I can remember, and for the most part those higher end Shaker offerings do produce enough sound and enough bass response to satisfy most owners. However, like anything in the aftermarket, some people just aren't satisfied with that and are looking for ways to improve with what the factory gave them. And that's pretty much what this kit will appeal to.
Now, I can personally attest those factory Ford subwoofers do leave a lot to be desired, especially if you like a more bass heavy listening style. Now, the problem is outfitting or upgrading the subwoofers without totally dominating the trunk space like those old bandpass boxes back in the day, but still at the same time providing you with enough low end response or bass to round out the other 11 speakers in the 401A Shaker Pro package. So, Raxiom JL, they put their heads together, came up with a solution for that problem and that's what we're looking at here today. But, let's break down the individual components here of the upgrade kit from JL and Raxiom, and the star of this kit, at least in my opinion, is no doubt gonna be the JL 12 TW3 subwoofer, which is just a massive upgrade over that 8-inch factory paper cone woofer in every single way.
Now, what makes the TW3 really special is that it produces a fantastic bass response, but it's still very shallow or very thin. In fact, this speaker itself is only 3.5 inches deep. So, that makes it very appealing to throw in tight spot like this because, as you can see, it really doesn't need a massive enclosure to sound really good. So, how did JL accomplish this with their TW3 line up? Well, they basically took a traditional woofer and just turned it inside out. And what I mean by that is, if you can envision a speaker, if you ever seen one outside of an enclosure, you know you have the cone and then the skeleton or frame, then hanging off the back of the speaker
