Hope someone responds...I did the same thing. Bought on ebay and no harness. I've been scouring the web for 3 weeks looking for info. Let me know if you come up with anything.

not sure where you can get the harness...

but, I'll tell you from experience, that the sub and amp aren't worth much...

however, it's a neat setup, and there are a couple 6.5" subs out there that you could replace it with, along with a small 2-channel amp you could bridge...

I have a Rockford Fosgate in mine...but the JL Audio 6W0 is another nice option:

Have to agree that the factory amp isn't worth it's weight in crap. Chuck it and get yourself a seperate amp. I have a 6 1/2 JL in a Tuffy console(might upgrade to the 8"). I modified the original woofer box to mount in the Tuffy console and stuffed the console with polyfill. You could probably buy an amp for what you're going to pay for that harness. The problem I have now is trying to get 6 1/2 alpines into the sound pods.

You have one other problem other than the harness. The stock radios all use the Chrysler "cabin equalization feature". This means that the factory loads the option list the TJ was built with into the EMIC (instrument cluster). This includes whether the original was a 4-speaker (no sub) or 7-speaker (with sub) setup. The stock radios will not output any bass below 120Hz with the 4-speaker option. To fix this you will have to pay the Jeep dealership to change the radio/speaker option using a DRB scan tool (about $100).

The cabin equalization feature pretty much makes it uneconomic to add any form of subwoofer without upgrading the head unit. It does not preclude upgrading a stock sub with a better one, provided the sub option is already enabled.

Hey, I'm in your boat. Got the install done except for the wiring. Found a post on this board about how to go about it: here

So it looks like it's just a matter of wiring it yourself and harness be darned.

I was at the dealer today inquiring about it and they were no help. What I heard him say was that the harness is part if the total Jeep wiring kit which would almost lead me to believe maybe, just maybe that harness is tucked away up in the dash somewhere? In just about every vehicle you play peek under the dash with, you can see multiple harnesses that aren't being used at all. Shot in the dark, but I might take that peek.

Skatch...you've got email. I did end up wiring it myself. Not sure if I got them all correct, but it plays some bass. Try www.installdr.com They have some wiring diagrams that should help. Find a local independent stereo shop (not Best Buy, etc). If you sweet talk them, they can print you out a wiring schematic for your exact vehicle's stereo....they all have access to that info.
For those saying that these subs suck...I agree... to a point. There is no doubt that you could have lots better sound, but for what I, and many others want, it is fine. Mine had no sub at all. When I added an ebay OEM sub (for cheap), it was like switching from AM radio to good FM radio. I'll keep my good stereo in my M3. For my Jeep which is noisy as hell, this is fine. Plus I don't have to worry about theft with the top off all night at a bar.

Hmmm...that site didn't have sub info, but I still bookmarked it as a good resource. I tore into my other friend's Jeep last night (it's amazing what people will let you do if you just don't ask). He's got the sub already installed from the dealer. I traced those wires around forever. Black/Pink to Yellow to LTGreen to Black/Red.............. I'll never understand the process that went into mixing up the wiring colors.
But now that I have some of the info, I'll take that knowledge to the install Jeep and see what it's missing and try to fill in the holes.
Now regardless of what some out there would say, the stock sub/amp my friend has (that is undoubtably run correctly) plays its heart out and gets down to business. I wouldn't want anything else out of it. So that's something to strive for and compare to.
I'd imagine b/c the wiring is such a complicated process, they'd want to keep it as simple as possible to install one for a lot buyer if they wanted the upgrade option. So I still can't rule out the possiblity that some of those unused wires are lying up in there waiting to be freed.
Only one way to find out.
Oh, and I saw on ebay right now some Shmuck is selling the plans on how to install a stock sub if you didn't have one already.

Shweet, I think I got it all figured out. In fact, I know i do!

It's still all taken apart, ghetto rigged to the lighter and some random grounded bolt. I just twisted the spkr wires together to test it all and I got bass, so I'll do it up right tomorrow. I'll snap some pics and stuff so you can see the install and final result.

K, I got it done, and it sounds as good as my friend's Sahara that had it installed at the factory. Best $37 I ever spent

Did a write up for the heck of it: HERE
