Bose Lux Amp install in T360 ?

[02redhawk]

Hey All....  New member, longtime lurker (guest).  I have spent the last 1.5-2.0 months searching and reviewing the LOADS of great info on the Bose Lux amp installation on this site...  The 40+ page thread(s) were very overwhelming, I must say.   

Now for all you savy Lux-Amp gurus (ie, sperry, etc.), I have a new one for you that doesn't seem to have much info buried in the archives.  Not surprising, since its for a Trailblazer as opposed to an Av.     For all the same reasons why as everyone else, I too would like to upgrade my non-lux Bose/Nav system to a luxury sound-setup.  There is little (read: NONE) information on the various Trailblazer/Envoy sites that I frequent regarding the lux-install, so I thought I would try here for some much-needed assistance....before I fry the amp due to my own idiocy.

Vehicle: '06 Trailblazer-SS with OEM TNR Nav (non-lux, UM8) & Bose (UQA), factory XM.

I have purchased & sitting ready for install the -044 H2 Lux Amp (used, already programmed for H2).  In addition, I will convert the non-lux TNR to lux (thanks machomachodan; he is local to me).   I am thinking of leaving the amp as-is with the H2 soundfield, and add the twiddlers to the D-Pillar in the truck...but I'm getting ahead of myself:

Along with the NAV reprogram, I believe the only other item that I will need to do is to reconfigure the connectors to the amp.  So, I am looking for tips or any T360-specific (Trailblazer, Envoy, Ranier, Saab 9-7) pinouts that may be different from the T800 lux-amp install.  That is, any conversions/rewiring to the existing connectors or new connectors that I must purchase?  I do have access to a Tech-2 for any additional (re)programming that is needed.  Any assistance that can be provided will be immensely appreciated.  I have located a couple past threads that the lux-install into an Envoy was "discussed", but not much closure/results beyond that...

Thanks so much!!

Mike. I'm certain that this will work but you would be better off getting a GMT360 Lux amp than the H2 unit.
That is unless you want a woofer project.

The GMT360 platform uses more full-range door speakers and no separate woofer if I recall, and the H2 amp isn't set up that way.

Find an early (03~04) TB or envoy Lux amp and rewire/replace what you have. You will need to find another connector (C3) for the mic & data connections.

The following has NOT been tested to date and would be for the H2 amp retrofit:

Hi SPerry, thank-you for the reply.

A bit more searching uncovered this (old) thread:
http://www.chevyavalanchefanclub.com/cafcna/index.php/topic,32249.msg508672.html

I also went to the stealership and got the following P/Ns for the '03-04 360s:

'03:  Only Amp P/N 15112642 was used.  "Amplifier, RDO Speaker, ACDelco #15112642, Usage: Premium Spkr System (UQA)"  List: $778.28

'04:  The above P/N was also used in '04, as well as the following other three:

15103800 "Amplifier, RDO Speaker (Analog Amp., not used with J6 connector.   Usage: Premium speaker system (UQA)"  List: $410.06

15112641 "Amplifier, RDO Speaker (Class 2 Amp w/ DSP Modes; uses J6 Connector.  Usage: Premium speaker system (UQA)"  List: $778.28

15135032 "Amplifier, RDO Speaker ***A Service Bulletin applies to this part number.  (its the "popping" amp TSB, FYI)  Usage: Premium Speaker System (UQA)"  List: $431.25


Now, I assume from the above that the preferred one is the Class-2 Amp (15112641).  But, correct me if I am mistaken (which occurs often in life...), but a Class-2 Amp doesn't necessarily mean that its the 'Luxury' Amp, correct?

While there, I also searched for any 'Luxury' Head-Units for '03 and '04, and none of the radios that came back contained the Y91-RPO in the item description...(?)


Thoughts?

Incidentally, the stock '06 Amp in the Trailblazer-SS w/ NAV is the 15135032.

And I think a better (reworded) question is - For the '06 NAV in the TB (UM8) converted to Lux, do you believe the 15112641 is the correct "lux" amp to work with it?  Or, do I have to leave my NAV (UM8) as a non-lux unit?

[sperry]

GM won't call the class II amp in a TB as "Luxury" because no Chevy's have that level, OEM (as Y91). I was too quick to call it Lux with the Class II being the important part instead.

I would seek the 15112641 or`2? and rewire the connectors; add the third one as it needs that. Have the interface changed to Lux, and that should work fine.

A new amp may need programming and that could be tricky. Hopefully the tech2 will override the model year (in the VIN) with the MY for the amp. Otherwise, you'll need to program the new amp in an 03. Perhaps the differences in the 03 & 04 is the 1512641 & 1512642 or V-V. However I don't have any resource depicting the differences.

The dumb amps (non-class II) are used in the later production units, a typical cost-cutting practice.

I have some diagrams of each type of GMT360 amps somewhere. You will need those diagrams to do the connector rewire. If you don't already have them, let me know..

HTH!

[02redhawk]

Thank you again Sperry.  I took your advice and ordered up a "Class-2" Amp for the T360 (P/N -2641).  Seems like the easiest installation to have the amp that was made for the platform instead of trying to patch-in the H2 Amp (although I'm sure it could still be made to work).

I *think* I spotted the 360-amp diagrams in a previous posting of yours, via the 'search'.  I will go see if I can relocate it...  Plus I gotta see if I can find that connector also.  Would it be available from the dealer?

[sperry]

You will need those prints to make the reference chart or whichever way you choose. Regardless, just as the GMT800's, the `360's are wired differently between the system types.

Here's two for the Envoy - They should be the same as the TB

The speaker wiring... Tricky, as both Class II & non class II are shown!

[02redhawk]

Hmm...  The '04 Class-II Amp has arrived, and it bears a striking resemblance to the Amp in our '02 Trailblazer (we have two TBs, an '02 and the '06 which I am doing the Lux/Class-II conversion on).  Our '02 (stock Bose) has NOTICABLY better sound reproduction and much better bass than the stock non-lux Bose in the '06 - all the things that the lux system will give me in the '06.

Anyways, the '02 TBs were their own unique beast, but after looking at the wiring pinouts on the '02 Amp, I am wondering if it mimics the wiring that I will need to convert the '06 to.   Have a look-see and compare to the schematics (thanks again, sperry) above.  Sure looks like the wires/colors are all going to the same pinouts.   Hmmm, wondering if I can use the '02 setup as an easy template to follow for the '06, if (when) I get confused following the EE diagrams.

This won't be the first time I've asked a stupid question... But, what is this and where does the wire get routed & connected to??? (DLC Schematics in Data Link Communcations)  I'm now within about 1 week of doing my Class-2 amp conversion, and this question is one of my most glaring unknowns...

I pulled this from the C2 and non-C2 speaker wiring in SPerry's posting just above.

   i own an '04 TB and an '04 AV.  the TB came with Bose & NAV.  the AV cam with Bose.  just like you mentioned 02redhawk, the TB has noticeably more bass than the AV.
   
   although Sperry mentioned GM will not call the system "Lux" if it is not in the proper "Lux" platform makes sense, but to hear the two vehicles clearly shows one is superior over the other.

   for whatever reason i thought my sound would improve with the installation of my new NAV radio in the AV.  it did not.  sounds the same.   which further proves my point...  the amp in the TB has to be a "Lux", or a "Premium" with some extra juice.

   from the info you provided i would say it is clear i have PN 15112641.  i have the DSP feature on my INR radio.  this obviously must be the difference in the sound quality of the two systems.  the '06 TB SS's with TNR do not have the DSP feature.

   so, if you get the 15112641 amp i think you will find what you are looking for in sound quality.  good luck.

[sperry]

Non Class II (GMT360) amp: Two connectors.
Class II amp (GMT360) amp: Three...
Other connections between the amps also differ.

A middle connector is for the class II specific connector/connections of a Class II amp. (noise cancelling microphone & class II DATA.)

[PUNISHER]

   i don't know how many connectors are on the amp as i have never had a reason to look.  however, from the info that i have read here, and in different threads, i would have to say i have the Class II GMT360 amp installed in my vehicle.

[sperry]

In the Envoy, it's under an (inside) cover at the left rear wheel well (LWB) or under the right rear seat (SWB).

I didn't yet look where the TB has it.. (If you really wanted to know )

The Spacious profile would be in the class II amps.

[PUNISHER]

   i have the LWB TB.  i will look in the rear for it.  the NAV radio has different DSP presets; one of them being "Spacious".  if i remember correctly the others are "Driver" and "Passenger".  i can't check now since it is at the dealer for a faulty rear climate control switch replacement.

[sperry]

You have the class II

But I'm sure you're still curious about looking at it.

SPerry -
Any idea where 2272 is routed to?

The TB (SWB) has the Amp stowed on the RH-Rear quarter panel, behind the backseat in the cargo area.  I'm pretty certain that's also where its at on the SWB Envoy as well.

   yes i am.  thanks for the location.

[sperry]

SWB Envoy's locate it under the RR seat. Perhaps the earlier ones are in the RH-Rear QP?

I wouldn't doubt they moved it at some MY point.

Possible.  My '02 Helms manuals cover all 3 360-variants; so for '02 its in the rear-quarter....but totally possible that its moved over the years.

Hey, anyone want a great-condition '03 Lux H2 Amp?  Need to sell the one I purchased and am not going to use for my lux-install (using a 360-specific amp instead, as you can see from this thread...)!  $225 shipped OBO. Email: redhawk02@sbcglobal.net
 

[PUNISHER]

   i would take Spery's advice on this one...  get the amp for the TB/ Envoy equipped with OEM NAV.  that's what we have.  let me tell you there is a noticeable difference in sound quality when compared to the Premium amp in my AV.  the install will be a lot easier too.

[02redhawk]

Yep, I have the Amp for the TB/Envoy sitting here on the bench... Only wiring question I am still trying to figure out is where circuit 2272 (DLC Schematics in Data Link Communcations) is routed to.... I'm waaay too leary to begin the swap until I can dig out this answer - otherwise I'll just have this loose-ended wire and surely the system won't work until I figure out where it goes.

[MichEnvoyBoy]

Ok everybody seems really knowledgeable here and Im having trouble coming up with answers on my own little NAV upgrade on my Envoy.

I have an Envoy with BOSE 6 disc changer, RPO UC6 and UQA.

I bought a NON LUX NAV head unit. Got the VIN cleared - chimes work but no music.

We played with the TECH 2 for about 2.5 hours trying to figure out why the amp wasnt channeling music. My amp # is 15070015 per the TECH 2. I have yet to take off the rear inner quarter panel to see if its got 2 or 3 connectors.

So what gives? Is there something else in my NAV head unit that needs to be programmed besides the VIN?
