The least expensive amps, I believe the $1400 do not go under the Jeep completely and really are not attractive.
XL is the only way to go and fold in to an encasement that kind of looks like a rock rail. They are roughly $2000 plus install so the price of 1800 plus the 500 seems accurate.
As far as I know and have heard AMP has taken the 392 off their list of approved vehicles probable due to the heat under the hood that has been known to effect the plastics..
I installed mine before it was taken off the list and they approved my warranty.
I am sure they are working on a fix, it is simple to move the control unit to inside the Jeep as all wiring is on the passengers side.
Pic 1 and 2 are AMP XL's, the XL sticker has been removed.
I do not see how a dealer is going to install a matching rock rail, they would have to be more specific there for me to agree to it.
Nice thing about the LP6 is Baja Design made it so the two outer holes in the pic 3 are where you mount the lights. simply remove the existing and the hole is the east fit for the LP6 base nut and bolt.
Pic 4 (from my Gladiator) is the plug that goes in the back of the light and then goes to the AUX switch junction on the passenger side next to the battery. You willl have to dig to find the pack of wires the first time. I use Aux 1, 2, and 3 for the LP6 as 1 is high beam, 2 is low beam, and 3 is the Halo which matches very nicely and I run the Halo day and night.
YOU CAN NOT RUN THE HIGH AND LOW BEAMS AT THE SAME TIME, BE CAREFUL WHICH HARNESS YOU BUY AS THEY RANGE FROM 40-90 DOLLARS. EXPLAIN TO SELLER THAT YOU HAVE AUX SWITCHES BECUASE THEN THE WIRE HARNESS DOES NOT NEED RELAYS ETC.
pic 4 is the wiring, as you can see in this example I only have one set of rear lights wired so one aux wire and one ground. Ground is against the passenger side fender with a blue water sealed crimp.
The Maximus-3 Grill Guard and LP6 work beautifully together.
On another note low beam is perfect for neighborhoods and high for country, off road, and all other situations.
If you run high beam through the neighborhood then all dog walkers bikers, and joggers etc are going to flip you the bird as it is just way too bright for them to even shield with their hand. Low beam they can look away slightly and its tolerable.
Pic 4 and 5 are a Gladiator with Maximus-3 and LP-s running daytime Halos
392 has same bumper. I will be installing same stuff on mine this weekend and you can see finished product when I post it. I have tried a nice LED bar but it just doesnt look as good as the LP-S because of Jeeps round lights
Any questions feel free to ask I have done a bunch of these.
