Ive had my Unlimited Sahara with nav and inifinity system for about a week now and love it. The factory stereo wasn't to shabby, but was lacking some thump in my opinion. So this past weekend I did my first of many mods by adding an amp and sub. Ive done this in pretty much every vehicle I've owned but this is the first that I stuck with the stock head unit instead of going with an aftermarket one, no point in that after paying extra for the nav and extras, so i was a little nervous trepidatious at first but in the end this ended up being the easiest install id ever done. I didn't even need to take the head unit out. Jut the front panel.
I figured Id share what I did in case anyone else was interested. I forgot my camera at work so there are no pics but it was such a simple install you really don't need them. Below are the Jeep specific things I did, i wont get into telling you how to plug wires into your amp or connect an inline fuse etc...
Power From battery:
I simply ran the power wire from the battery over to the drivers side below the master cylinder there is a little black rubber circle you can poke threw with a screw driver and feed the wired through. From there i just ran the wire under the plastic panels along the side and door sills. You can pretty much just push the wire under with your fingers no need to take apart the interior. I ran it all the way to the back tucking it under the carpet.
Remote Power wire:
Thanks to searching the forums I fond the easiest way to do this is to tap into the drivers side cig/accessory outlet. You do this bu pupping off the front cover and splicing into the wire. The hardest party was getting my big hand to feed the wire back through the dash through the access panel under the stearing wheel. Once you get past that just follow the power wire you installed.
Seeing as how the stock head unit does not have out puts for the amp you will need a line converter, I picked mine up at bestbuy for 15 bucks. I was gonna run it from the headunit back but after taking the sub out i saw it had four wires connected to it so on a hunch i just tapped into them and it was like magic. No need to run another set of wires all the way through the jeep. it take a little playing with the wires to figure out which ones to attache where. different line converters will have different color wires i'm guessing so you will have to do a little playing yourself. After you get it right just tuck the converter (depending on its size) back under the carpet and your good to go.
I installed a 12" Kicker L5 Solo Baric and a Kicker 600.1 amp. I had to turn the amp all the way down or it was just too much bang, even now If i crank the stereo I set off car alarms and stop old peoples hearts. But the highs from the stock speakers go great with the new low end from the sub. In my last car i replaced every audio component and it didn't sound as good as this.
