A while back I did a completely new install including HU, components, coaxials, amp and sub back when I first got the Jeep. You can read here if interested: http://www.wranglerforum.com/f40/2012-hu-speaker-amp-build-log-155755.html

In that build I put a JL 8" W3 inside of the factory "sub tub" and used a MDF ring spacer to make it fit due to the longer/bigger magnet. I spent a good deal of time getting it to sound just right with all the speakers and the sub. The one thing that I could not get right was the rattling issue. I put CLD tiles inside and outside of the tub, put all sorts of padding behind it in between the tub and metal, etc. No matter what I do it still rattles in certain songs. Im thinking the sub is just too powerful for the plastic and it vibrates the whole assembly.

So I decided to yank out the sub tub and get the non-sub rear plastic panel that comes on Jeeps with no rear sub. It looks just like the drivers side. That will provide enough space to drop in a new box right in the same spot. Stopped at the dealer and the panel was $85 with tax. Not too bad.

I swung by my local sound place and they had a custom built box on the floor that caught my eye. It was from another project that someone had built and I guess did not want it. It was originally for a Smart Car. It had JL 8W1 in it and the odd shape and size of it is what intrigued me. Sorry no pics (I know, I know)...

The inner cubic ft was built around the space requirements of the 8W1 which is almost the same as the 8W3 requirements. However the odd angle of it was damn close to what I would have had built. I asked them to add a terminal plug (red/black buttons) so I could take it in and out as needed. It currently just had the wires poking through.

I grabbed the box as is with the 8W1 and ran outside to test it out. It sounded better than my 8W3 in the sub tub. And zero rattles. Can't wait to hear it with my 8W3 inside.

Everything should be in mid-week next week so I'll post up pics. In the meantime I ran some loom over my speaker wires on my amp to clean them up.



Here is the current rattle machine:

Got a call from the sound place that the sub was all set. Grabbed the W3 out of the sub tub and brought it down. Dropped in perfectly. Routed the wiring to the terminal and put in some polyfill.

I used a +/- solid bananna plug to put onto the wiring from the amp so I could easily remove the sub if needed for room. it basically is not a 2-prong plug that goes right into the terminal on the box. Plus if I disconnect it, the wires won't touch.

No rear panel from the dealer but shold be in tomorrow. I yanked the sub tub and got it ready for the install. Im going to get creative and re-install the 12v plug either using the factory one or grab one from RadioHack and connect to the factory plug. I like the option of it back there and want to keep it. More on that as it happens.

Fired up the stereo and there is crystal clear bass with zero rattles. A better and deeper bass note compared to the same speaker in the previous sub tub. Best part is it does not rattle. No it is not a boom machine but that was not my intent. I just wanted to have the bass that you feel and not the bass you hear 1 half mile away.

Quick pics of the sub:

Finally got the rear panel in from the dealer. It figures that Mopar changed the panel just slightly in 2013 and the top plastic piece that snaps into it at the top to enclose the seat belt mechanism is just slight off. Looks like I need to order a new little top matching piece. Not sure why they changed it but it is slightly different.

I got the panel in and got it installed. Pretty easy. I made an opening and put a grommet in to run the wires through. Then covered with the loom to make it match everything else. Installed the quick release bananna clip. Now I'm off to find a quick disconnect snap style hook system to work with the factory metal loops that hold the panel in. That way the box wont move around. It slides on the mat.

Only odd thing is now my cargo mat that was designed with the sub now has an opening. Oh well.

It's not a 2013 change on the small piece. the small piece for the outside portion of the sport bar is just slightly different to mate to the non sub panel for some reason. I think 2011,12 & 13 are the same. Same thing happened to me on my 2012. There are two part numbers for that piece, one for the sub and one for non sub.

I wish I would have made a trade when I sold my sub on eBay, sell sub and trade for buyers two panel pieces. I realized the difference before I shipped the sub and sent the small panel piece with it to the buyer since it was useless to me and he would need it for his install.

This is good to know. I figured Jeep would have made 1 single small piece to save on costs but I guess not. Ill order the small piece part number for the non-sub and it will be back to normal. Small little imperfections like that drive me crazy.

Don't want to hijack but quick question... I have a tuffy deck in my jku. Want to make more room under the deck. Is there enough room to remove factory sub and get someone to build a box with aftermarket speakers between the rear seat and the deck panel?

Not sure how much room is in a JKU between seat and Tuffy deck. I actually just got in my Tuffy Security enclosure and the sub will actually be tucked inside. I need to cut out a bit of the left edge to sit over the amp and wiring. But the sub will fit inside perfectly. That way nobody can walk off with my amp and sub. Well not easily...

Amp:


The Plan (note the marked area). This provides room for the Tuffy deck to just fit snug near the amp. Actually flush with it with the amp inside the secure area..

^^ Tailgate install is a nice idea. I could not run all of the wiring to the tailgate. I have a 4 gauge power, 4 gauge ground, remote in, 3 sets of RCA, 4 sets of speaker wires and a set of sub wires. That would not be fun to run to the tailgate (minus the sub set).
