I'm upgrading the stereo in my 06 LJ, but using an OEM RB1 Nav head unit, running through the JL Audio Cleansweep into ARC Audio amps.

I need to know what the pinout is on the main wiring harness so I can sort out the speakers and remote amp turn-on.

I also am trying to sort out how the 7 speaker stereo is wired to the subwoofer. From what I gather on the 'net, the pinout has R/L speakers for F/R, but no separate sub output, although there are a couple wires in my harness that I haven't identified.

I've tried the Modified Cars, Car Radio Wiring Diagrams, Car Alarm Wiring Diagrams, Car Light Bulb Size Guides - ModifiedLife.com website, but it's not correct for my '06.

Any help with this would be greatly appreciated.

FWIW, the system will be:

RB1 w/ iPod and Sirius inputs
JL Cleansweep
ARC mini 125x4 to four Focal 5.25 Coax (stealth)
ARC mini 500x1 to a rear seat box w/ JL Audio 13" shallow mount sub
ARC mini 125x2 to two Kicker 6.5" subs in the floor kickpanels

I'm also lining the tub with sound deadening material. It should sound great, and be completely stealth.

Additionally, I'm installing:
front and rear seat heaters
homelink/compass/maplight/autodim mirror
Escort 9500ci remote radar w/ laser jammer
Electric trailer brake controller
rear fog/reverse lights (Hella Micro DE fog)
LED's in guages and interior lighting

I've already installed HID hi/low lights (xsighting lighting/Sylvania) and KC HID fogs, LED tails, and a few other items.

It'll be sort of an 'Overland Rubicon' edition, I suppose.

If anyone can help with pinout info, it would be much appreciated!:confused:

This is the crazy part. The subwoofer has all four speakers hooked into it. There is no separate subwoofer output.

Thanks very much, this should be very helpful.

I couldn't believe the sub is connected to all four speakers - I kind of gathered that from other diagrams I'd seen, but just thought 'I can't be reading this right'... It saves me some money on a signal summing processor though.

I assume that means the OEM speakers have crossovers limiting bass downstream of the head unit, i.e. they are perhaps 'crossed over' by the sub?

Thanks again for the quick reply!

As far as I know it is built into the amplifier in the subwoofer unit.

blown sub speaker replacement

I had to take out my sub speaker since it blew somehow. It sounded awful. I happen to have a pioneer TS-G1641R sitting around that can be dropped into the enclosure once a couple of holes have been drilled. The problem that I am having is that there were four leads attached to the old speaker, one pair, red and black, the other, gray and tan. These went to separate contacts on the old speaker. Not really knowing anything about car audio, I would just like to drop in the Pioneer that I have sitting around. The fact that there are twice as many leads as I expected has made me question what to do here. One guess that one set of the wires was for power and the other was for signal, but reading this post, it is possible that one pair is for the right side and the other pair is for the left side. If anyone could give me a tip on how to quickly put this, plug and play style, I would appreciate it. Otherwise, the remaining speakers sound fine and I'll just go ahead and leave the sub out completely. I listen mostly to talk radio or audio books so the sub is overkill anyway.

the subwoofer in the center counsel is a dual voice coil, 4ohm that is why it has the four wires
if you want to replace it cheap i would suggest using either the AUDIOPIPE TS-VR6 for around $20 or the LANZER MAXP64 for around $40, these are the perfect replacements cause they are both dual voice coils (4 wire) and close to the factory 6 3/4 size

Edit by Jerry Bransford: The factory subwoofer is a dual voice coil speaker, but 2 Ohms impedance at each of the two voice coils. Not 4 Ohms as stated above.

I have a 2006 Jeep Wrangler Sport with the 7 speaker system and I been researching replacing the subwoofer for a while, i just replaced factory stereo with an HD Radio JVC KD-AHD69 that cost me $140 but subwoofer sounded like garbage with all the new power, radio was an easy hook up with instructions and install kit from Crutchfield.
only thing that took a while was soldering the two harnesses together which i recomend rather then using solderless connectors also would sugest using shrink tube rather then tape, just make sure you slide tube on before you solder wires, lol. I am looking at two subwoofer replacements, AUDIOPIPE TS-VR6 150 watts peak power, 75 watts RMS power and 25oz magnet for around $20 and the LANZAR MAXP64 600 watts peak, 300 watts rms power and 40oz magnet for around $40,


I hope this helps anyone trying to find a replacement for their factory subwoofer in the center counsole

The factory sub amp sux. Replacing the actual sub will gain you back what you had before.....and your head power has nothing to do with the sub power......might gain a bit of sharpness and lose some muddle with a better cone.....but it's the crap signal going it that needs to be fixed as well.

ok, so what happens if I stick a single voice coil speaker in that i have sitting around collecting dust? should i try and combine the two sources or just use one and cap off the other?
Honestly i don't know what could happen either way, i was just giving you a cheap fix for the factory system, i have read of others combining the wires but you have to becareful what you read on here cause some people want to believe they know what they are doing but have no clue. i would call and talk to a professional tech advisor before you go crossing wires to see how it might effect the amp.
for my jeep since i already replaced the radio i decided to elimnate the so called subwoofer and factory speakers and i am installing some Infinity Marine Series 6000M speakers that clamp to the rollbar and two Pyle PLBASS10 low profile amplified subwoofers under the front seats all of which run on seperate amps

i know the HU Power has nothing to do with sub but the way jeep has it wired you have no seperate control over the subwoofer. they should have put in sepreate volume and freq controls for the sub but then no one would be blowing their speakers, lol

the sub woofer

sorry to hijcak... but I just installed the JVC radio also and have a question. I have a sub woofer and it doesn't seem to be as loud as when I had the factory head unit in there? I have what I assue is the 4-speaker? Two console and 2 rear speakers (with sub). How can I get more bass? Do I need to hook up the sub RCA jacks on the back?

Are you using the factory sub, if so, did you hook up the rempte on/power antenna wire comming off the radio harness (Blue with white stripe) to the power on (blue wire) on the jeep harness side?
i am assuming you hooked the red switched power to the red on the harness and the yellow to the yellow on the harness.
only other thing i can think of is my radio has an adjustment for freq and volume -10 to10 but that only works if you using the rca jacks in back with i am assuming your not
so check the blue and white wire from radio and make sure it is going to the blue wire on harness which is the amplifier turn on
these wire colors are for my 2006 jeep, i think they are the same from 2003 thru 2006 if you have the 7 speaker factory set up

Use those RCA's on the back of your new HU for when you upgrade with an additional amp and separate sub woofer speaker and enclosure. Until then, ya don't need them.

I just put a new head unit in my '05 LJ and it used the 22 cavity gray connector, but the wires were different colors. The circuts are the same, just different color wire. Here's a rundown:

1 - Bl/Pk
2 - Teal/Gr
3 - Or/Br
7 - Gr
8 - Gr/Bk
9 - Gn/Bk
10 - Gn
11 - Bk/Gn
12 - Bl/Pk
13 - Gr/Or
14 - Wt/Pr
18 - Gn/Bl
19 - Gn/Or
20 - Gr/Or
21 - Gr
22 - Bk

Hope that helps someone!
