2015 Cherokee "Alpine" DOOR Speakers Step by Step Upgrade

Hi everyone,

Vehicule Information:
==============
2015 Jeep Cherokee Trailhawk w/ Nine Amplified Speakers With Subwoofer

The Situation:
=========
As I had aftermarket sound systems in almost all my previous vehicules (I'm now 40 years old), I purchased my Cherokee TH with the Premium "Alpine" system. Why ? Because from that point, I thought it could be enough and would not (for once) require an upgrade... again...
Don't get me wrong here, the Cherokee's amplified system is not that bad. To be honest, it's one of the best factory sound system I have experienced. However, after three months of tests and listening, I have to admit the "Alpine" system isn't up to my expectations.

Ok now what ?
==========
First, don't even think about replacing the head unit, period. Now, do I feel like the amplified system is playing the music loud enough, yes. That said, to me the obvious upgrade option to enhance sound quality was to change the factory speakers for better products.
NOTE: This is what I would call a "Stage 1" upgrade. Therefore, all 9 speakers will be replaced but for now I will keep the subwoofer as it is. With the new speakers in place, a Subwoofer upgrade might be considered, or not.


NOTE: I had to split my project in THREE different THREADS... 1-DASH... 2-DOORS... 3-REAR PILLARS



Before We Begin:
============
Please understand that I'm NOT and I DON'T CLAIM TO BE a car audio expert. I do have some experience installing aftermarket radios and speakers in my previous vehicules but that's it. Chances are I may be wrong and/or do some mistakes along the project. Your comments are always welcome but please be gentle as I do this with good faith and to help. :-)



Door Speakers
==========

Driver interior door trim...



Pull the door handle and remove the plastic cover



You need to remove the bigger 10mm socket screw ONLY



Using a plastic tool, lift up, remove & unplug the door control module



Using a small flat screwdriver, insert and lift up the door pit rubber mat



Remove the hidden screw



Once you have removed both screws, you'll have to PULL the interior trim out. I recmmend to start
pulling near the speaker grill on the lower corner. Pull and soon enough you'll hear some "POP!" since
there's plastic clips all around the door... BE CAREFUL since you CANNOT separate the interior
trim from the door, two wires prevent this... By the way, DON'T WOORY if some plastic clips breaks
in the process, we'll cover that later...





To remove the speaker, you'll need a tork (T25) screwdriver bit



Factory speaker connection



Speaker housing, I prefer NOT to cut anything...



Here it is ! The factory door speakers ! One-Way 6x9 speakers... Note that ALL door speakers are
IDENTICAL, same part number. Sorry... NO ALPINE LOGO... Something interesting, for the front
doors these speakers act as component with only BASS output... while on the rear doors, the exact
same "one-way" 6x9's do act as full range speakers... Not good...









Door 6x9 speakers are 2.0 Ohm... important to know to purchase the right replacement speakers...



Replacement speakers are JBL GX962, measured at 2.7 Ohm... that's close enough to the originals...



Metra 71-050 Adapters, required to connect the new speakers WITHOUT cutting or skinning anything



Factory speaker VS replacement JBL unit...



Allright, since the new speakers were a bit too BIG for the door housing, I needed a solution to avoid
cutting anything... the problem was the new speakers were too deep so I used some foam tape and
applied all around the speaker bed. This way, I had the extra height needed and the foam is compressed
when bolting the speaker in place which may prevent vibration. I like !





On the picture below, you notice I have only 2 screws installed... BUT... after a few try, I was finaly
able to use ALL THE 4 SCREWS... YES it's possible... start with one screw, just a few turn, keep it
loose, and then start another for just a turn or two, and so on... at the end you should get all 4 screws
in place...



IMPORTANT :


TEST THE NEW SPEAKERS BEFORE YOU REPLACE THE DOOR TRIM !


For the REAR DOORS the process is almost identical.


One last thing...


Remember the door clips, I DID BROKE TWO over the 4 doors in the process... So I went to the dealer
and I got some of these replacement clips for about $1 each... If you break one or more, REPLACE THEM
since you sure don't want the door to shake & rattle at high volume... Part # 06510766AA...










Final step is REAR PILLAR speakers ! See my other posts !

Great write up, I will probably have to upgrade my premium system at some point as well. Like you said, it's a really good system, and probably the best I've heard from the factory, but I do crave more.

Yes, the process is the same for rear doors. The screws are located at the same spots.

Have fun ! :-)

Nice write-up. I have 3 questions:
1. What kind of difference have you noticed since changing out the speakers to those particular JBL's?
2. Why did you choose those particular speakers over any others?
3. If you had to do it over, is there another set of speaker that you would consider using?

Agreed! Excellent write-up! I will definitely be following it when I am ready to upgrade.

I'm also very interested in the decision behind the JBL's. I've never used them in any of my previous stereo builds but I'm definitely looking to upgrade the upgraded "Alpine" setup in my TH. Besides the JBL's I've seen mention of a Kicker setup (non-Mopar) and Rockford Fosgates that "mostly fits" within the Cherokees. Are there any other speakers out there that are worth looking into?

Hello fdegree,

Sorry for the very late reply... Here's the answers:

1. The new JBL's are better quality units and can handle more power (especially bass), therefore deliver sound better.

2. First, because of their impedance (Ohm) rating... 2 Ohm rated speakers are not very easy to find among aftermarket speakers. Using 4 Ohm units is OK too but they would be quieter so we'll have to raise the volume a little higher to experience the same volume level as the 2 Ohm units.

3. Any 2 Ohm rated Speakers would be my first pick over 4 Ohm ... the JBL's were 2 Ohm and on budget... however, I know there's some much more expensive units that could fit as well...


Regards, iBypass ;-)

I just replaced my four door speakers with Rockford 6 x 9 two ways. I use the Metra harnesses from Crutchfield. The overall sound is a lot better there is definitely a lot more bass. I originally had a pair of Rockford 3 1/2 inches however they were too tall to fit under the grill. I did order the JVC's so I think that with the combination of 4 two way speakers plus the two on 3 1/2 inch speakers my system should balance out pretty well. I did find it with the door panels lining up the doorhandle piece back on to the plastic tab on the door panel was kind of a pain but overall it wasn't that bad of a job
