I have a 2012 unlimited with the basic stereo system (non infinity). I intentionally got the non-infinity system bc I knew I wanted to do custom stuff later and didn't want to be hassled by the factory sub and amp.
I just ordered an infinity reference 8" 1000watt subwoofer and a small amp to power it.
I'm building a custom box to fit under the rear seat. I have a car seat in the center of the back seat so I never fold/flatten the flat seats.
I also ordered a set of infinity reference tweeters that I'm going to install into the sound bar.
I'm not sure how much of a pita building a box for under the rear seat will be so I also ordered a basic box for the 8" sub that can sit in my rear floorboard on the driver side (since no one ever sits there). This will be a temporary solution while I build the custom under seat box. I'll post photos after the install.
I'm considering putting the amp under the front passenger seat.

My question is:
Since I'm already using the driver side cig lighter/12v charger as my power source for my hardwired gps, radar detector and small hella driving lights I don't want to put anything else on that fused accessory power source.
IS THERE ANOTHER CONVENIENT ACCESSORY POWER SOURCE BESIDES THE CIG LIGHTER?
I'm trying to avoid wasting hours of time searching and prodding w a volt meter.

Thx guys.

 

See if you can't hook into the fuse box....and just another 2 cents because I learned the hard way....be careful about mounting electronics in the floor. I woke up last week with about 6 inches of water standing in my floor boards because it decided to rain a day early.....it would def ruin the amp and could possibly short out many other legs of the electrical system. Not shooting your idea down but u never know when u might get caught in a storm with the top down.....

 

Double d:
Thx for the advice.
I'm fabricating some kind of rack for the amp to sit in under the passenger seat that keeps it off the floor. Good call!
Do you know which fused relay under the hood would be best for running the remote for the amp?
Thx!

 

It (the elevated amp rack) might also serve as a heat sink via the seat frame, as well as letting more air around the amp to keep it cool.

 

Just installed a pair of infinity reference 1" dome tweeters on the b pillar above the seatbelt.
Spliced into to rear speakers.
Also filled sound bar w polyester stuffing.
All I can say is WOW WHAT A DIFFERENCE!
My highs and mids are amazing and crystal clear now. That damn rattle/distortion in the sound bar is gone now. Like most mids I've done, I strongly feel that it shouldve come this way from the factory. I hope jeep visits this site and takes some notes.
Now that the top and middle of the sound range is perfect, the jeeps ready for some low end.
Sub goes in Saturday morning. Can't wait!
Sorry for the shitty phone pic, but u get the idea...
