2013 Jeep Wrangler Unlimited Sound System build

Time to start the stereo install. I am slow so this thread may take a while to complete. I may not even include all the pictures but I will try. I went back and forth on different head units and never could make up my mind. I started with the Alpine ICS-X7HD, then Kenwood DNX890HD, Kenwood DNN990HD and after the Kenwoods clunky interface, I went back to the Alpine ICS-X7HD. The Alpine does not have as many features but it is simple to use and cost about half as much. I will wait and see whats in store for the 2014 line and may upgrade then but for now its the ICS-X7HD.

Equipment
Alpine ICS-X7HD
Alpine PDX-V9
JL Audio C2-650 components for the front
JL Audio C2-650x for the sound bar
Sub is still in the air, but looking at the JL Audio 10TW3D4. I will either build a box and dump it under the passenger seat or build a removable fiberglass enclosure just behind the back seat against the side of the tub. I like the 10TW3D4 because its shallow mount and it hits as hard as any 10" I have heard. I am still researching this so the rest of the system will be finished before the sub.

Project plan:

Install head unit. This is already done, but I am going to pull it out and rewire it. I will get rid of the speaker wires since they will not be needed on the harness. Yeah..Im a little OCD when it comes to this stuff but there is enough junk behind the dash.

Feed power line from battery to under seat.
Run amp turn on line along side the power line.
Run new speaker wires to the correct locations
Install speakers and polyfill.
Mount the PDX-V9 under the passenger seat with the amp tray (acquired from jeepedjeep)
Temporarily run speaker leads to the factory sub. It probably wont last long with 500 watts being pumped into it..but I probably wont crank it up until I get the sub done anyway.
Run the ground wire and attach to seat frame or tub.

First pic is just the initial under the hood stuff. 4 guage power line all nice and wire loomed up with Memphis Audio AFS fuse block.

Im not taking pics of all the speakers, but this is the idea.

1 x JL Audio C2-650 component woofer
16 gauge speaker wire
gold quick connects soldered, crimped and heat shrinker
Polyfil
A bead of blue RTF to seal between speaker and enclosure.

More progress. Between running kids around and going to lunch and dinner this has take much longer..but again..there is the OCD part of me that doesn't really make it go any faster.
Pic 1: running wires behind the instrument cluster. Main speaker wire, tweeter wire and hands free microphone.
Pic 2: wire ties holding the JL Audio tweeter in the factory tweeter location. Couldn't think of a better way to do this. They are almost tight enough to stay in place, but this provide a little insurance.
Pic 3: Finished tweeter
Pic 4: Mounted cross over (and wired) on the metal plate
Pic 5: Cross over plastic cover installed

Pic 6: barely enough clearance but the cover fits nicely.

If you notice I also added the JL Audio grill covers to the enclosures before I mounted them. I didnt want to throw them out not store them, so they fit just fine behind the lower dash panel on both sides.

Forgot to mention...The passenger side crossover is mounted underneath the glove box. I used velcro to mount it to the inside of the lower dash directly under the glovebox. It is easy enough to remove if I need to make adjustments or change it out.

The rear speakers are done. I basically followed the same steps as the fronts. I pulled the entire sound bar out and installed the speakers on my workshop bench. I ran the speaker wires through the rubber grommet that is in the sound bar. Getting the speaker wire through it was not easy because it already had the factory speaker wires and dome light wires going through it. I used a round 4mm hex head (no sharp edges) and folded the wire over it and punched it through and repeated for the 2nd leads.

I have not mounted the amp yet so the excess speaker wire is wound up and stuffed up underneath the passenger side roll bar padding. Amp will have to be later tomorrow as work comes first now.

I had a couple of PMs about why I didnt take it to a car audio shop to do this. I guess its like a suspension or any other Jeep mod. You get a little more satisfaction doing it yourself. Another reason...In my 20s (a long long time ago) I spent 5 years building custom car audio systems. I worked for a custom shop and we built some of the best sound systems on the east coast. This was back in the mid to late 80s when Rockford Fosgate, Alpine and MB Quart and ADS were big names for high end equipment. I guess the names are still pretty big. I have been out of the industry a long time so it was kind of fun to research all the equipment. Should be a fun project..

Very awesome build, my friend. I've been considering doing Polk Audio all around in my 2012 JKU (Artic Edition). JL Audio was my first pick, however.

Have you gotten around to installing the sub yet? If so, are you using the factory enclosure and what make/model did you go with?

More fun for the sound system.

Pic 1: Trial fit of the amp
Pic 2: Tray and amp mount between the seat rails
Pic 3: Making a good ground spot. Between the front passenger seat where the seat legs there is a small oval hold. I drilled a 1/4" hole next to it and put bolt in it. Then (seen in picture) i used the radio pullout tool, bent it in an L shape and tack glued the nut to the tool. I stuck it down in the oval shaped hole threaded it with the bolt. Now the ground bolt is very tight. I also took a small sanding tool and removed the paint in that location so a good metal to metal ground.
Pic 4: Finished ground wire
Pic 5: Finished except for clean up.

I hope you seal off that amp in case your top is off and that amp gets wet.

the amp in that bracket sits up off of the floor and the seat totally covers it....You can't even see it. I painted mine black and with the top and doors off (all summer) never had any issues.

PS nice Bracket and set up

If the amp gets wet, I will have bigger problems to deal with than the amp.

Very nice build so far. I love watching other OCD audio peeps doing great work. Reminds me of my build I'm the same way. My install took a VERY long time as I am anal and finish each step perfectly before moving to the next. Then I think about it and go back and make improvements. That is the fun part.

Nice underseat bracket. I thought about that but with all of the heated seat wring and dual flip/slide seats (2D) there wasnt much room. Plus I didn't want to yank the seat out. So I ended up with the amp on the drivers side rear panel in the back tucked right behind the seat.

Always appreciate watching others do things right. Such as the correct connectors and heat shrink. Same for me. Do it right and never have to worry. Not to mention the safety aspect. Relays are your friend. Great build so far. Interested in the sub portion of the build.

For the most part I am finished. I still have some clean up to do. I have also started testing subs so that part should be fun. For now I have a JL Audio CS112RG-W3v3 12" box. I may drop down to a 10" but not sure. I was able to buy the enclosure for about the price of the woofer alone so the box could be used as a permanent solution or I could remove the woofer and build something else. Obviously security is a concern but I am thinking about going with the Tuffy Security deck and keep the box locked up in there.

Pic 1: Bracket mounted under the seat
Pic 2: Bracket from the front. Plenty of clearance and not part of the seat touches the amp.
Pic 3: Bracket from the rear
Pic 4 - 5: Various pics of the sub box. This is temporary and may be modified. More to come.

I think I finally picked a sub I can live with. I ended up getting the JL Audio CS112LG-TW3. I test a couple of different subs and picked this one for a couple of reasons. The sub got great reviews so I had to hear it. It pops..and I really cant tell a difference between it and JL Audio 12w3. The TW3 is a thin mount sub and this one comes in the seal enclosure. It is small and easy to remove. Security is a concern so I also just bought the Tuffy Security Deck that this will sit in side.

JL Audio in their infinite wisdom embroiders their logo on the front of the speakers. Translates to STEAL ME...Im a JL Audio speaker enclosure. So..one way to prevent this is install 1 1/4" rubber feet on the top of the sub, turn it over so it is down firing and with the top on (tinted windows) it is almost invisible. Plus I like the down fire solution anyway. It works well with the top off the Jeep.

Next. In the next couple of weeks..I am going to peel the carpet off and fiberglass the enclosure and re-apply carpet or maybe bedline it. I want it element proof. I spend a lot of time at the lake and usually leave the top off the Jeep. The Tuffy deck lid is mostly water proof but not entirely. If you have ever seen MDF board and rain..Its not a pretty combination. The stuff almost dissolves. So that should solve my sub problem.

My solution for the white feet...I went to home depot to see if they had them in black. I used 1 1/4" rubber let tips from everbilt. I purchased a 1" dowel and cut the dowel to the right size to fit in the rubber tips. I removed the woofer and drilled a 1/4" hole in each corner of the top of the sub. I also drilled a 1/4" hole through the center of each wooden dowel. From the inside I used a 1.5" fender washer and 1/4 - 20 x 2" bolt. I hammered a 1/4 - 20 blind nut into each each dowel through the drilled hole. I screwed the wooden dowel on to the sub enclosure with some blue locktite and stuck the white rubber tips on. I ordered some black rubber tips on line and will replace the white ones when they come in.

Man, your Jeep is so close to how I imagine mine.

I'm curious if you have any system/engine noise? Did you run your head unit power and ground to the battery or use the harness? Curious as I dread this.... I have a Pioneer headunit on the way. Then I will be adding my old school Autotek Bass Thrust amps and some speakers.

And your Jeep is coming along great! Looks; and i'm sure sounds, spectacular.

Thanks...I grounded the radio to the chassis. There is no system/engine noise whatsoever. It is extremely quiet.

Update on my audio system. I upgraded the head unit to the INE-w927hd back in late October. Alpine finally released SIRI update for this head unit last month and I am very pleased with it. The JL Audio speakers and sub sound incredible with the top on or off. Cant wait until warmer temps so the top can spend more time off than on.

And I thought my sound system trumped most JK owners. Great job. I am running Memphis components front and rear. Pioneer comp 12 in a custom box. Box is huge, takes up a lot of space but throws a ton of bass. I rarely haul anything other than coaching equipment. I, too, am nervous about getting caught out in the rain-good thing I have a soft top.
