A while back my brother picked up a WJ style Grand Cherokee Limited with the Infinity "Gold" sound system. When I heard it I was absolutely blown away at the sound quality and the absolute pound from the stock system... After research I found that the WJ Infinity system is rated at 180 watts, 6 speakers and a 6 channel amp. The system absolutely and hands down BLOWS the "360" out of the water even the LHS "360" that I had found to be even better than the original AB amp. What really brings out the thump in the system is the use of 2, 8" Infinity subwoofers from the Hyundai Azera. Best part, these woofers are dual voice coil, and the plug is the same as the LH!How did I get these in the spot of a 6x9? I placed these in my rear deck using the bracket that holds the subwoofer in place from a 2000-2003 Maxima/I30/i35. It"s a metal shelf that fits perfectly over the existing 6x9 opening and creates a mount for the 8" woofer! I sealed the base of the bracket with 3m window weld ribbon and it also keeps it in place and absorbs rattles!On to the specs:The Jeep Infinity Gold consists of 2 2.5" midrange speakers in the dash, 2 6x9" in each front door, and 2 6.75" in each rear door. The amplifier is located under the passenger side of the rear seat in the Grand Cherokee. As with the LH, the WJ many different revisions of the amp and the first revision is the best. Amplifier: 56038407AC (used in the first run of 1999 model WJ, I have yet to find one in a yard but this is WJ holy grail amp) AD revision is the most common and what I am currently running. Sound is incredible. I removed my Basslink it"s that good! The revisions go up to AG however the sound quality degrades with each revision. The issue with the amp is that it uses different connectors. It can be installed in one of two ways. Cutting your harness and splicing the connectors in place of your existing or making it almost plug and play. To do this You will need to purchase a 02+ Chrysler radio adapter harness that will plug Into the 22 pin LH amp connector.Now, the WJ uses PCI same as the LH. However, the WJ BCM sends a message to the amp that it is in a WJ. What this means is the lows are sent to the front door woofers and full range to the rear doors. When the PCI is not connected it defaults to low frequency to the rear and midrange to the front doors! Ideal for the LH cabin. The front doors can"t handle the amount of boom that would come from them in WJ form! So when you look at the jeep wire diagram don"t worry about the PCI input.What I used:Scoshe CR02B radio harnessPig tails from an LH amplifier harness so that I could repin the radio harnessCouple of male terminals I harvested from existing unneeded harnesses to create plug for the 12 pin amp harness.Wire crimpers Butt connectorsElectrical tape2 8" Infinity subs from 06+ Hyundai Azera 2 metal plates from 00-03 Maxima/i30/i35 for 8" woofer into rear deck2 Jeep WJ infinity rear door speakers (for front doors part number 56038410AC)Jeep WJ amplifier pig tails ( I pulled as much of the harness as I could so I would have extra wire)Diagrams:LH amp connectors:WJ amp connectors:If you have the "240" watt system you don"t need to do anything for the rear doors but what you will get out of the rear is low frequency only. If you have the "360" or want to keep your rear door speakers you have two options.
1 jump the signal from the dash speakers(which is what I did) or use a crossover from the rear door speakers and connect the rear doors from the crossover.To keep your center channel:Use the signal from the left dash + and the right dash - if you have not upgraded your center to a door style sail speaker or better, doing this will blow your center speaker in under 1 minute at any volume more than 1/4!Use the above diagram to connect the proper wires to one another from the LH to the WJ harness. Test to ensure that it all works and be amazed at the sound quality difference between the two amps! Bob, Ron, Tyler and many others didn"t believe their ears when they heard this at Carlisle! They all though that I had dedicated Subs in the trunk and that it was not all factory equipment! I will get more pictures of everything when I get a chance!Let me know if you have any questions!
