I just did the same in my '13 JKU Sahara. Was very easy, and I haven't installed a sub/amp in anything before. First question: Does your stock system have the rear subwoofer?

Well, that might make things a little more challenging. Since you don't have the stock sub, you'll need to tap into your front speakers with a line output converter to get a low level signal back to your amp. I'm thinking that the quote of $500 you got was for a very fancy loc. I just bought the Scosche (sp?) one which didn't even cost $20. Run RCA patch cable from the line output converter to your amp and you're golden.
Oh, and for the remote amp turn on, I tapped into the pink wire in the wire bundle that is beneath the steering wheel.
If I can help anymore, let me know.

I just, literally this morning, fixed the crap job that best buy did wiring my 2011. It won't get deep into how crappy it was, but the didn't ground it correctly, and they basically just ripped out the dash to get it in, while breaking some of the plastic in doing so)

It sounds like you have the base head unit like i did, so here is the is just like wiring any auto with a factory head unit ( splice into connections to feed the stereo signal to the amp and then to the speakers, etc...). But, there is zero point in doing this if you don't get a line out converter to correct the output on the factory stereo. The stereo is configured for the shit of excuse for factory speakers, meaning it is greatly reduced so it doesn't blow the paper cones. There are plenty of posts about this.

The Line out converter will correct the sound, and deliver the tones that the aftermarket speakers (not to mention the amp) need. I would highly recommend any product built by Audio Control. I got the LCi-6 and the difference in sound is incredible!!! I mainly listen to metal, rock, and talk radio. All of it sounded fantastic, and I have yet to even put in the after market tweeters and sub. Already so much better than stock. This is the one I bought from Amazon: . The company makes plenty of versions, so find the one that suits your need.

As far as installing the LOC....also a breeze if you have wired an amp before. Just think of it as a pre amp and install it in line between the stereo and amp.

I know you have speakers already, but I am also going to throw this out there. A jeep is made to ride topless, constantly in the elements. So, you need to make sure you have weather resistant or marine rated speakers. I highly recommend Polk. All of their products are water resistant,and I think sound amazing.

Let me know if I can help. I was where you are several months ago. Good luck!

Wow, for $500 you could get a new head unit that is easier to wire in an amp and sub. Thats what I did anyway. I shopped around for a great deal with install and they installed the head unit, bought the head unit, installed a sub/amp that I bought off Amazon, and hooked up my fogs to an external switch for $600 total... They are def trying to screw you. As the previous poster stated, you would have to tap into another speaker connection, I don't think I would go this way. Head units now adays are much cheaper for so much more. The watts are usually always better than factory too just my thoughts.
It's better to regret something you did do, than to regret something you didn't do.

Hey guys I have a 2013 JKU sahara with the stock alpine 8in sub which I feel is perfect if you adjust the base a little. I was recently carrying a propane tank I'm my trunk and some how broke my sub grill. I was wondering if any of you guys were willing to sell me a spare one if you're not using it. Thanks

I have a 2014 4 door sport. I had the crappy stock radio so I bought the RES version on ebay. Not much better. Anyway, the original jeep didn't have a sub. I bought a stock sub from a friend. The wiring was in place so we hooked it up. We can't get any sound from the sub even with the new stock head. Any suggestions? Thanks
