: Installing Kenwood into '01 Catera with factory BOSE using GMOS-06

I'm installing a Kenwood KDC-MP342U into my '01 Catera. I scrounged around for the best deals on the adapting kit pieces.

I needed the Metra 99-2004 dash fit kit, the Metra GMOS-06 harness kit to use the OEM Bose amp and speakers, and an antenna adapter.

I ended up buying the GMOS-06 used on ebay, previously used in another installation. In going over the harness and see what and where I need to splice, there is a wire that looks cut. On one side of the adapter, there is a 16-pin plug, there are two black wires coming out right next to each other, one of them is cut and 2" long, the wire coming out next to it goes to another plug but at the base there is a small stub of another black wire. I want to know if these are the same wire that was cut in half accidentally upon removal. I took a few pics, let me know what you think...
If anyone works in an audio store and you have this kit in stock, can you please report back what the plug looks like fresh out of the box? Thanks

I'm getting ready to do the same thing.....

I was looking for information before buying the head unit, adapter, and mounting kit this weekend.

Are you aware if there is a way to still utilize the 12 disk changer with an aftermarket head unit?

I know some one that wired the 12 disk changer to the rear AUX ports of his deck. He also managed to incorporate his steering wheel controls. He has a double-din deck, I can't remember the make or model. Will be doing sound upgrade soon, I have non bose system so I don't require the adaptor...Keep us posted if you find any info or head units that work.

I like the fact that people are upgrading from the ancient sound system GM put in our cars... best thing is i'm putting in a set of 15's with 2400wRMS total output with both subs and a 2500wRMS amp at 2 Ohm. With this im removing my old subwoofer setup and installing the new one. Cars with BOSE need to have the sound processor removed and have wires bypass the sound processor to go directly to your speakers. The small amp, however, can easily be used to amp all speakers with your new headunit!

PART ONE:
THIS STEP IS TO BYPASS THE SOUND PROCESSOR AND AMPLIFIER>>>> IF YOU WANT YOUR SPEAKERS AMPED WITH YOU NEW HEADUNIT SKIP TO PART TWO....
Here's all the pinouts and information you'll need to make a simple and hopefully quick sound system installation. This picture here is needed to identify the locations of certain wires, due to the fact that there are 3 or 4 wires of the same color. All you need to do is simply mark the wires from the SOUND PROCESSOR INPUT and find the wires for the AMP OUTPUT, from the AMP. All the speakers are amped, so you will need to find the OUTPUT wires from the amp and crimp them to the INPUT wires on the SOUND PROCESSOR. Simple installation.

PART TWO:
THIS PROCESS WILL ALLOW YOU TO HAVE YOUR NEW HEADUNIT AND HAVE THE FUNCTION OF THE FACTORY REAR AMP. HAVE NOT TESTED HOW THIS WILL SOUND BUT MAY SOUND GREAT. ALL SPEAKERS ARE AMPED WITH THIS.

Now, the small amp can be used to power all of your speakers. What you need to do for this is take the SOUND PROCESSOR INPUT wires and mark them. Next, find the AMPLIFIER INPUT wires and crimp them together with the corresponding wires. Now, take the SOUND PROCESSOR DIAGRAM and locate PIN B1 and crimp that to PIN 25 on the AMPLIFIER ENABLE INPUT on the amp. This will turn the amp on when the radio is on, allowing you to have not only your headunit's internal amp working but also have the stock amp working inline to have all you speakers pumping out sound.

If you have any questions pleas ask and i WILL help you to the best of my knowledge. Thanks:)

Okay, continuing my install after a weekend vaca, I looked carefully at the cut wire and realized it was in fact labeled with micro printing as a chassis ground and the black wire next to it was as well, I spliced the two together and then went on to tidy up all the wiring. Here are a couple more pics, I will update again when I install it into the car.

Here's the new deck in the dash kit, the fitment isn't 100% but once installed you wont be able to notice anything.

Is that the Metra Dash-Kit?

yes, its the metra, i think model number 99-2004

I want to follow up with my install experience, I will update again with a picture how-to. For now I will just say that it is not as straightforward as the Metra install kit and adapter box instructions imply.

Cliff notes following by the book instructions:
12V+ constant to the radio is not present and must rewire
Amp turn on lead always on, speakers hum like you have the volume cranked up to the max with a CD paused, must rewire.
Dash opening is tiny, stock radio rear support must be trimmed out to fit aftermarket radio and wiring.
Fit kit has 4 arms to screw down like the factory radio, only 2 of the 4 reach, spacer tube must be added with longer hardware to fully support.
Ashtray rubs bottom of fit kit, does not open easily like before.
Bottom of fit kit has a step, ashtray "spring flap" catches on it and does not allow opening of the ashtray past halfway without sneaking a pen or something in to hold down the flap first.

Looks amazing... I like how the new unit looks.

Q1... is the new unit going to be able to power the OEM amps... ?

Yes, I am running it to the OEM amp and speakers, it does sound very good. There is a Gain knob on the converter box to control input level to the OEM amp in case the preamp outputs are too high voltage.
The main reason I upgraded was the factory deck couldn't always read my burned CD's. Now I can listen to any CD I burn and it also has a USB card reader port right on the front so I can just plug a thumb drive in with songs in folders like multiple CD's.
I'm real busy with work and school so I don't know how soon I can finish the install write up.

I installed a DualDin Kenwood with the metra kit, just cut out the lower pocket area and it fit perfect for me. It isn't going to be perfect but it doesn't look bad and it was very simple. I just want a way to get my steering wheel controls working agn. =(

You can see a gap on the side. The upper (largest) part of the gap is only about 1/4" wide, i've thought about going back and putting a light ring about it but it hasn't bothered me enough yet. :bigroll:

Trust me, it was a clusterf*** wiring that thing, to top if off, the constant 12V isn't constant so I lose all my presets every time I turn the car off and more than 5-10 minutes pass. It was such a whore stuffing the 5lbs of wiring into the dash opening that I have yet to take it all back out to troubleshoot, plus its been pretty cold here for months now. Oh and the ashtray rubs against the bottom of the trim panel pretty hardcore, good thing I quit smoking or I'd go nuts dealing with that thing.

I've read through this instruction a couple of times, and I must say it's about as clear as mud. Could yo possibly clarify this with some pin numbers?

Both the black wires are grounds. That wire on my kit is cut as well. Can't remember if I cut our not though. Hope this helps you

So I'm assuming that B1 (Red Wire to K134) is supposed to be constant. But where would the ignition wire go? Also I have no illumination on my deck when trying to install. I figured wiring would be easy as I'm running non-bose. But wiring colors and everything are not the same as previous decks I've installed. Anyone tell me why I have some power, as deck will take and eject discs, but no playback, no sound and no illumination?

AHazzardToAll
03-30-10, 02:40 PM
try flipping you lights on, you may have spliced your remote/acc on into the illumination from the stock wiring, otherwise it's just your rem line. i re-ran a new constant and remote from the fuse panel.

Matera97
04-19-10, 03:55 PM
Hazzard, just wondering, what fuzes did you run the wires from? Did you incorporate power from K134? As for the OEM harness, there are 2 constant power sources. Red from K134 Pin F1 as well as a Green/Grey wire from Fuze 26 Pin F4. Why the two contants?

AHazzardToAll
04-19-10, 10:50 PM
My remote came straight from the acc fuse under the dash, and i ran a new pwr from a true constant.

Matera97
04-20-10, 02:30 PM
True Constant??? The battery??

AHazzardToAll
04-20-10, 06:21 PM
I used an existing one, but I'm not sure which one. One from the battery would work too. I think the one i used was a "PWR" fuse but I'm not sure.

Matera97
04-20-10, 09:06 PM
Well I just had some mild success! The illumination signal only comes on when the side markers are on or if the lights are on. This is the same for Pin F4. The constant, ground and speaker wires were the only ones that I didn't change. So I have Illumination at E5 and ACC at F4. So I'm getting play back and lights and everything. Its a temporary fix until I can muster enough courage to tear out the fuze panel and run a new ACC.

AHazzardToAll
04-20-10, 10:33 PM
If you run your constant for the yellow stock bose "constant" then you're going to loose all your presets and settings. It onlu stays on for about 5min after you turn the car off. I've thought about actually using it as my acc in at one point, but if i did that i would have killed my battery with all the power going to my amp.

Matera97
04-21-10, 07:36 PM
I don't mind having to turn on the side markers for ACC, I can get over that...This non-constant constant, will be trying. You should look for what fuse you hooked the constant up. Did you just solder the wire to the fuse? Stuffing all those wires was a big time hassle. And I know why JRamanos kit didn't fit right, those two little mounting holes for the Deville and the tabs on the top need to be removed, or you'll experience exactly what he was talking about.
