2011 Bose Subwoofer Upgrade

Just bought a 2011 Sierra SLT with Bose audio system. I am upgrading the factory subwoofer with a JL Audio Stealthbox that mounts under the center console. I had a heck of a time finding the wire diagram for the Bose amplifier. I needed that info because JL says their amps can take the signal from the Bose amplifier right into the RCA inputs. The factory Bose subwoofer is a dual voicecoil speaker. It is powered by four wires that come off the Bose amplifier output harness. Dark Blue and White is left +. Light Green and Black is left -. Dark Green is right +. Light Blue and Black is right -. These wires will feed directly into the RCA inputs of an XD600/1 by using an XD-CLRAIC2-SW speaker wire to RCA adapter. That is how JL says to do it, but they were no help in identifying the wires. That information is straight from the GM CK Truck Electrical Manual.

 

Here are some Delphi part numbers for the connectors so you don't have to hack up the wiring. The pigtail on the Bose subwoofer uses these parts available at Mouser.com

 

Mouser Part #: 829-12064761

Manufacturer Part #: 12064761

Manufacturer: Delphi Connection Systems

Description: Automotive Connectors 4P MALE BLACK 150 SERIES 14 AMPS

Mouser Part #: 829-12047787

Manufacturer Part #: 12047787

Manufacturer: Delphi Connection Systems

Description: Automotive Connector Accessories SECONDARY LOCK BLUE

Mouser Part #: 829-12047581

Manufacturer Part #: 12047581-L

Manufacturer: Delphi Connection Systems

Description: Automotive Connectors MALE 150 SERIES TIN CBL RNG 2.40-1.84MM

http://connectors2.delphi.com/dcsgdmcs/del...S01_S01.tif.pdf

 

OR THE FOLLOWING DEPENDING ON THE THICKNESS OF WIRE YOU ARE RUNNING INTO YOUR AMPLIFIER.

 

Mouser Part #: 829-12059894-L

Manufacturer Part #: 12059894-L

Manufacturer: Delphi Connection Systems

Description: Automotive Connectors MALE 150 SERIES TIN CBL RANG 2.4-1.70MM

THE LAST TWO NUMBERS ARE PINS THAT CRIMP ONTO THE WIRE AND FIT INSIDE THE CONNECTOR. THERE IS NOT A LOT OF DIFFERENCE, I JUST ORDERED 8 OF EACH SIZE TO TRY THEM. THEY ARE ONLY 17 CENTS EACH.

 

ONCE ALL THE PINS ARE CRIMPED AND PUT INSIDE THE MALE CONNECTOR, (FIRST PART NUMBER) THERE IS A LOCK (SECOND PART NUMBER) THAT WEDGES INTO THE CONNECTOR TO LOCK THE WIRES/PINS IN PLACE.

 

THE ENTIRE ORDER CAME OUT TO LESS THAN 15 DOLLARS AND I ORDERED ENOUGH TO DO TWO, IN CASE I MESS THE FIRST ONE UP.

 

THIS IS MUCH BETTER THAT BUTCHERING THE ORIGINAL WIRE HARNESS AND MAKES IT MUCH EASIER TO GO BACK TO STOCK IF YOU EVER WANT TO SELL YOUR TRUCK THAT WAY.

 

 

THE REST OF THE SPEAKERS THAT ARE RAN OFF THE BOSE AMP USE A DIFFERENT CONNECTOR. THE STOCK HARNESS THAT PLUGS INTO THE BOSE AMP HAS 8 WIRES THAT FIT INTO A 16 POSITION FEMALE CONNECTOR. THERE ARE 8 EMPTY POSITIONS ON THE CONNECTOR. THAT CONNECTOR IS DELPHI PART NUMBER 13520382.

 

http://connectors.delphi.com/DCSGDMCS/DCS/...Number=13520382

 

ONE COULD FAB AN ADAPTER USING THIS CONNECTOR ON ONE SIDE TO PLUG INTO THE BOSE AMP AND ON THE OTHER END HAVE RCA CABLES TO RUN TO JL XD SERIES 4 CHANNEL AMPLIFIER. YOU WOULD NEED THE CONNECTOR AND 2 EA. OF THE JL AUDIO XD-CLRAIC2-SW ADAPTER AND 8 EA OF DELPHI PART NUMBER 13526678 OR 13526680 (PINS THAT ARE CRIMPED ONTO THE ENDS OF THE WIRES AND PUSHED INTO THE CONNECTOR).

 

THE OUTPUT OF THE BOSE AMPLIFIER IS FILTERED SO THAT VERY LOW FREQUENCIES ARE NOT SENT TO THE FRONT OR REAR SPEAKERS.

IF ALL AFTERMARKET AMPLIFIERS AND SPEAKERS ARE RAN DIRECTLY OFF THE BOSE AMPLIFIER, THEN THE SYSTEM WILL STILL HAVE WHATEVER PROCESSING THE BOSE AMPLIFIER HAS. I AM NOT SURE BUT THERE MAY BE SOME DELAY HAPPENING IN THE FRONT LEFT SPEAKER CHANNEL AS WELL AS VEHICLE SPECIFIC EQ-ING. DEFINITELY HIGH AND FLOW PASS FILTERING, BUT SINCE THE FRONT TWEETERS ARE IN PARALLEL WITH THE FRONT DOOR SPEAKERS THEY ARE PASSIVELY FILTERED.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
