Let me start by saying that I am not an audiophile. A decent sounding, stock stereo is all I need. My 03 TJ came with a blown sub. Not that I need a subwoofer, but since it's there I'd at least like it to work.
I found GCJoe's TJ Factory Sub Replacement thread
and thought for $19.35 shipped, I'd give the Pyramid 6 1/2 subwoofer from Parts Express
a try. I took some pictures as I installed it and thought I'd post them here.
It's a simple project that took me less than an hour to complete. That includes taking pictures.
While I used a cheapie sub, I suppose this would work for any sub you might try to install.
Here's a picture of the replacement subwoofer. Looks impressive.
Start by removing the rubber liner from the front cup holder. Use a 10mm socket to remove the bolt.
Next, remove the rubber liner from the rear cupholder. Use a t30 Apex to remove the bolts. You can now lift up your center console.
Next is the electrical husk. Usually they have a red lock on them that you have to click over first. My center console had been removed a number of times by the previous owner. I don't see the red lock, so I'm thinking he broke it. Oh well, no matter. To separate the husk, push down on the tab with a small screwdriver and pull the two halves apart. Yours may look different for a different year Wrangler, but the idea is the same.
Now, lay your console on the workbench upside down. There are two gold brackets, one on the front and one on the rear or the sub enclosure. If you look, you notice that there are push nuts holding these brackets to the enclosure. You need to remove these push nuts without destroying them.
Front push nut.
Rear push nut.
Using a very small flat blade screwdriver, gently open the "teeth" of the push nuts. Do this by carefully prying between the teeth of the push nut and the plastic bolt that they are attached to. You don't need to open them much and you don't need to bend all of them. Once you've pried a few of them open, use a pair of needlenose pliers to remove them.
After you get the push nuts off, use the needle nose plier to push the teeth of the nut back down into place. Basically you are going to flatten the push nut. Well, not completely flat. You want to move the teeth back just enough so when you reinstall the push nuts they will grab on the bolt again. This will make sense when we put everything back together.
Lay the console on it's side and remove these three phillips screws. You can now slide the enclosure out of the bottom of the console.
Remove the four Apex screws that hold the sub in place. They are size t15. Then, break the seal between the sub and the enclose by gently prying with a screwdriver. Remove the factory sub from the enclosure.
