Okay well, as some may have read I am in the process of installing the factory full floor console in my 04 Sierra 2500HD... Well The console I recieved has the bose amplifier, and sub in it, and I am really starting to think I want to hook it up... now before every body goes off and tell me to install after maker it will sound better, I really want to keep every thing looking original, and not be running wires all over the place in it(I already have enough of those). So I took apart the console to see what amp it has in it. The console came from an Avalanche(on one of the lables), and had the following on the label of the bose amp:

 

10394518

AMP ASSY 5800 GMT 800/805 CREW

**BAR CODE HERE**

25722120802902 - 05006224

**ANOTHER BAR CODE**

994518

 

IF I do this, what will I need, I know I will have to get a bose HU, but which ones will work??

 

Also what cables will I need, and part # if available??

 

Thanks for your help guys!!

i think you might need to get the complete wiring harness for it. that runs from the back of the deck down to the amp then wiring to run from the amp to the sub... ill take a look at my dads truck when i get a chance... he has the upgraded bose system

I figured one of you guys who had don the nav upgrade would have some guidance...

 

 

 

 

It can be done but it won't be easy. If will have to get the whole audio system harness and make sure you get the one for the type of amp you have (Y91- lux amp or the non lux amp). The amp number you listed is a non-lux amp but if your going to do this swap, I would get a lux amp and replace it. Then the BCM will need to be programmed so it knows that it is now supporting a Bose system. You will then need to install the whole harness from the headunit down to the amp and from the amp to each speaker. The wiring you have now just comes out of the headunit and goes to each speaker. I can't give you any part numbers, but could could get with the dealer. You will need to get one for a extended cab because they never put the bose setup in the regular cabs.

You may check with JP Customs, I believe they where going to make a setup to do this same type of upgrade.

Hmmmm... Has anyone tried to make a wiring adapter for this??? Or does anybody have the schematics that shows the pin outs for both the HU and the AMP??

Here are the pinouts for the headunit (they are the same for all headunits) and the two different amps (the lux bose/Y91 and the non lux Bose)

I spoke with Jason at JP Customs last week... he said it would only take a bit of re-wiring and to have the truck flashed to tell the truck it has a bose system... What exactly does the flash do?? Does it activate the pre-amp outputs on the radio???

The reflash programs the BCM so it knows it is controlling a Bose headunit. The radio will still need to be replaced with a Bose unit. Only the Bose models have pre-amp outputs. the non-bose units only have speaker level outputs (amplified)

Ok, what is a lux Bose vs a non lux Bose? What is lux?

 

Same questions about BCM, what does that stand for?

 

Where were you able to get the schematics for the plug? Is this in a tech manual or you found it on line or . . . ?

A lux Bose is the Luxury model witch uses a digital amp with DSP (digital signal processor)

A non-lux Bose is the regular Premium Bose model and it uses a analog amp and does not have the DSP built into it.

The lux-Bose systems can be identified by the RPO code "Y91" in the glove box or by looking at the amp.

 

The schematics can be found in the GM service manuals or CD's, the mauals can be bought from Helm Inc. http://www.helminc.com/helm/homepage.asp?r...=AS5&q=helm+inc.

 

The BCM is the body control module in the vehicle and it controls many operations from windows, door locks, lights, driver settings, radio functions, power mirror functions RAP, DIC, and many more.

Can I replace my non-lux amp easily with the lux amp? and what will I gain from doing this? Has anyone on here done this with their truck?

 

I have thought about adding an additional sub/amp combo but if the lux amp will increase bass and sound quality I might be interested in just doing that.

You can upgrade to the lux amp, and they do sound much better, but there is not much difference in the bass.

 

To make the upgrade you will need to remove and reposition all the wires in the two connectors at the amp and add a new wire from the radio to the headunit and also add the sound compensating mic. The upgrade is really not that hard and I can provide the needed wiring changes for you.

I think I may be interested in that project. What kind of dough would it take?

Not much money once you find an amp, the rest is just wiring mods.

Here is the wires that need to be moved in the 24 pin connector to go from a non-lux amp to a lux amp.

A1 - do nothing

A2 - do nothing

A5 - move to A4 (brown wire)

A6 - move to A3 (yellow)

A7 - move to A8 (dark blue)

A8 - move to A7 (light blue)

A9 - move to A5 (tan)

A10 - move to A6 (gray)

A11 - move to A9 (light green)

A12 - move to A10 (dark green)

B1 - cap off, not used (gray/black)

B2 - cap off, not used (purple)

B3 - cap off, not used (black)

B4 - cap off, not used (dark blue)

B5 - cap off, not used (dark green/white)

B6 - cap off, not used (brown)

B7 - move to B3 (orange/black)

B8 - move to B6 (light green)

B9 - move to B4 (dark green)

B10 - move to B5 (tan)

B11 - cap off, not used (pink)

B12 - move to B7 (bare wire)

Add data bus wire from B1 (small orange wire) on the headunit 24 pin connector to B10

Add microphone wire to B1 (optional, but recommended for the sound compensated volume to work)

 

 

 

Here is the wiring changes for the 8 pin connector on the non-lux to lux amp swap

 

A ( black w/ white) do nothing

B (dark blue wire) move to E

C (dark green) move to B

D not used

E (bare wire) just remove and cap off

F (light blue w/ black) move to G

G (light green w/ black) move to D

H (orange) do nothing

      Towing In Loose Gravel

      By Z45 · Posted

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.
