I started off using txst8tj's drawings from
TXST8tj - downfiring sub enclosure and trunk - JeepForum.com
I changed them up a little. I centered the woofer so that it sits between the latch on the driver side and third brake light connector on the passenger side. It also allows me to access the tie down on the passenger side that I use for my son's carseat. I mounted the amp on the passenger side also.

Did you build or purchase the sub box? What year is your Jeep? 2 or 4 door?

I built a down firing box for an old school Kicker Comp from the days when they were still quality (not sold at Wal-Mart) made by Stillwater Designs. It has been sitting in my garage for 10 years. I made the box for about $40 for the MDF and Carpet from Lowe's, and bought the Sound Ordinance M-2100 from Crutchfield for $63 (open box). I can't believe that this Kicker will still hit as hard as it did 15 years ago, and I am very impressed with the Sound Ordinance amp. I am even using the speaker level inputs so that I can keep my factory head unit.
I replaced all the factory speakers with Kickers a while back for less than $100, they were open box buys from Crutchfield and came with the mounting brackets and harness for free.

|CoreyZ||I hadnt really thought about it. I have a temp 10" in it now and it sounds good (rockford fosgate from my 08 evo). Not too punchy so im not really needing to tune it much. Once I get the 10W0V3-4 I will reevaluate.|

Since your gonna run one sub for a while, are you going to do anything to temporarily decrease the air space to what is needed for a single sub?

This is my amp install I just did. Originally wanted to mount them under the seats, but there wasnt room for what I wanted. So ended up mounting them in the footwells of the rear seats (I have a 2dr). I wont ever have the rear seats in again since I will never have kids and only have a dog so not worried about that. I am planning on also making a click in metal shield that will cover the entire rear footwell area and protect the amps when the dog is in the back.
Ignore the clamps on the plexi and the one loose plexi. Took this pic before I was done.
I am also removing the carpets so I can bedline this summer.
Also making a custom fiberglass enclosure for my sub in the back where the stock one was.
Im making it for 2 10" subs but for now leaving one hole sealed up and running just 1. Eventually I am considering doing the second sub with a second mono amp.

Got the fan mounted below the amp, drawing up the cooler air and firing it at the sub. Feels like it moving air pretty good.
Will know more after I get a chance to out the amp under load.
|05-20-2013 11:19 AM|
I turned the gain down quite a bit and drove around for a while. Amp was much cooler, but the gain was too low for my liking.
The amp has good air flow...I basically have it mounted where it's free-hanging, so it's got airspace on all sides.
Picked up a 4" 12v case fan....am going to mount to the underside of the amp, so it'll draw cooler air from below. That should help some.

|Barmanvarn||I did some research and according to everyone that has these series of amps, these things run hot. makes me feel a little better as I've never had an amp get so hot it could burn me.|
|05-19-2013 11:13 PM|
|05-19-2013 10:07 PM|
I think it's just that brand of amp. There is plenty of airspace/airflow in this location.
And if it was getting to hot, I assume it would have tripped it's safety.
Dunno, just thinkin' out loud.

|10Anvil||^That is why my installer told me not to put them in the dash.|
|05-19-2013 09:55 PM|
Posting here in case anyone else is interested (will PM if you don't see this).
Got my PBR series mounted under the stearing column and went for a drive this evening. I was probably driving around for about an hour, all the while I had the radio cranked up pretty high.
I got home and reached up under the dash to check the temp on the amp.....damn thing was so hot it would have burned me had I left me had on it. I know amp has a built in temperature protection and it never cut out on me so I have to assume it wasn't having any issues.
I wanted to check w/ you and see if you've found your PBR series amp(s) running hot.

If you are willing to risk new/used items you could budget about 2K fully installed.
I'm going to be adding a remote bass knob to control the mono amp gain because I listen to a lot of different types of music. You can't just set the amps and xovers and expect every genre to sound right. There are actually pretty significant differences between genre's and even albums depending on how they were recorded at the studio. You will also notice that sirius sounds like crap (low bitrate): same is true of playing itunes music via aux etc...
I would also suggest going to a shop and listening to the components you are thinking to buy (feel free to buy used or somewhere else - yeah I'm an ass).
Different component sets can sounds completely different on the same music. Especially tweeters. You need to find out if you like 'harsh' tweeters or 'soft' tweeters.
Aluminum dome tend to be harsher but work best with rock/metal music. I prefer softer tweeters and the component set I have play the highs a little too sharp for me. Going to try to adjust that with the xover points and lower gain on tweets.
After the install you have to spend a few hours getting the sound dialed in. Once I picked up my car it sounded like complete ass because most stereo installers won't touch gains etc... because they don't know what you like.
I also need to add some polyfill to the dash speakers, the way the dash is designed they are basically playing 'free air' right now and I'm losing some midbass.
For the sport bar I would only add some midbass, I don't think they need tweets up there.

|staindsoul||That looks really really good. I might need to steal your set up. About how much should I budget for it?|
|05-19-2013 05:34 PM|
Couple more pictures, as I said, nothing unusual or an eye sore. Sub box is actually pretty stealthy, especially with the stock box still in there. Plenty of bass with top down.
|05-19-2013 04:59 PM|
Got my new punch installed done. One less thing i have to worry about being stolen.
Mount is temp right now. My change it later.

I thinking putting a factory sub box in my JK may be the approach I need to take. As I'm limited on space using the factory box would keep me from having to deal with an aftermarket box being in my way.
|05-19-2013 12:21 AM|
The only thing you can see that looks different than stock is the new 'shelf' in the trunk/rear. The amps are under the driver and passenger seat, sitting off the floorboards by 1 inch to avoid possible water. The Focal components are in stock location, can't tell anything is different. Deck is a Kenwood DNX9990, lots of equalization and crossover controls. My sub is a 12w6v2 in that box firing down (reason for slit at bottom) and it hits HARD!
Seats still fold down and that box can be removed easily with a quick disconnect if I need the space. I'm going to remove the stock sub box once I get the replacement panels. Actually looking to swap my stock sub box panel w/sub for someones stock panels.
I now have the stock speakers, amp, and sub w/ panel available. $200 plus shipping or $100 plus shipping if I get your rear passenger paneling for the trunk.
I'll get more pictures in the morning of the amp location and deck.

|10Anvil||My system is complete. Sounds great and the box turned out awesome.|

|10Anvil||How big is that stock amp?|
|05-17-2013 06:27 PM|
|05-17-2013 03:45 PM|
New amp arrived. This thing is tiny!

|Barmanvarn||I believe under the steering column. Up under the dash.|

|10Anvil||Decided not to go with the JL Stealth Box. It is not a plug and play deal due to changes with how the premium subwoofer is installed on the alpine systems in the 2012-13 JKU. You have to buy two new panels once the stock subwoofer is removed. Also the mounting kit that comes with the stealth box no longer work perfectly. I've opted to have a box made with the subwoofer firing down so that the sub and box look like a storage bin/shelf sitting in the trunk area. It won't cover the rear trunk storage bin and should look stealthy and not attract the wrong kind of attention. I'll post pics when complete.|

Question. I saw i guy put his kickers/ sub under rear seat. How much room would be in the seat to put in the kickers/ sub? Also coul i even fit then in the seat or under it (with the box)? And finally would i need to remove anything important in the seat?
