Deciding if I want to install the KICKER SSICRE14 (Model 19303118) subwoofer only in a 2017 Sierra SLT w/Bose.  I pulled the driver kick panel off to take a peek at the wiring to see if I could locate the speaker wires that I'm supposed to tap into.  According to the instructions, I'm looking for a (Blue and Blue/Brown twisted pair) which I understand is the left front door speaker.  Question: is it possible that my truck doesn't use Blue/brown wires, but rather blue/orange as seen in the photo?  This is definitely the harness that goes up and into the driver door, but separating out all of this bundle, I don't see any blue/brown wire twisted with a blue.  These wires [see photo] are slightly larger in gauge than most of the other wires in the bundle.  

 

I cannot find a schematic of what the Blue and Blue/Orange wires would be connected to if not the speaker...  Before I attempt to install I wondered if anybody else has run across this?  

 

Also, those with this set up, does the amp shut off immediately when the ignition is turned off and the drive door opened or does it stay on for a period of time?

To me, the picture looks like blue/brown wire twisted with a blue. I've never looked at the green light on the amp, but I would assume it does. Are you concerned about the amp draining the battery?

Thanks for the reply.  I feel like this is one of those photos on the net where people are saying the dress is one color or the other. HA! My wife & dad both thought the wire was blue/orange stripe twisted with blue. I guess these are the only wires in the bundle going to the door that remotely resemble the instructions so it's got to be the right ones. 

 

Yes, I was concerned about battery drain... for whatever reason, my 2017 has been through 3 batteries in 5 years and 50k miles - I assume this is going to exacerbate this problem.

I wouldn't worry about the battery. I installed this same setup in 2017 and I've never had an issue, even after the truck sat for 2 weeks.

The only difficult part for me was fishing the power wire through the firewall on my SLT.  I used a piece of actual eletrical fishtape to push through the grommet and I was able to tape the power wire onto that and pull the fishtape through with needle nose pliers under the dash.  Took me about 3 hours total with at least 50% of the time spent on that step alone. The rest was about another 1.5 hours including cleanup.  It isn't going to rock your socks off, but it is enough for me and my kids who ride back there.  Good luck!

    • I was using recirc/max air. Especially if it really hot i start out by lowering the front windows a little with regular ac the go to recirculation after a few and rolling windows up. And it does not have the newest refrigerant. It has per the info under the hood r134. Not the new r1234yf.  
    • tldr; Shade tree mechanic stumped by variable displacement AC compressor.   Not Silverado related, but for my 2000 Camaro SS. I've never really used the AC since acquiring the car a good handful of years ago. I plan to take it on a trip this summer so I wanted to make sure the AC was in good shape. On an 73 degree day in the shop with the car idling I set the AC on "Max", temp set to cold, and fan on hi. The compressor turned on and air turned nice and cold.   I let it run for several minutes but noticed the compressor never cycled off. The engine was up to temperature enough that it began cycling the cooling fans on high. I had a set of manifold gauges hooked up and it was consistently at about 25 psi on the low side and between 200 and 225 psi (warm engine) on the high side. Per temperature charts, the low side is low (should be 30-35) and the high side is a little high (up to 170 per chart). I read the low pressure as potentially being under-charged underscored by a continually running compressor This was also underscored by temp readings of mid-20 degrees at the vents. Not just cold, freezing cold. Switching off the AC but leaving the HVAC fan on high produced a deluge of condensation underneath the vehicle. I was getting ice buildup on the evap core most likely.   The low reading (25psi) concerned me that the compressor wasn't switching off so I swapped out the pressure switch. No change in behavior, still ran constantly.   The AC clutch works fine as it engages/disengages with the HVAC switch on command. The compressor relay is good as I swapped it with two different known good relays just to be sure. Having eliminated that, and the pressure switch, I added refrigerant, thinking the constant run and low "low" pressure were signs of a slight undercharge. Makes sense, the car is 26 years old and it doesn't appear the AC system has ever been touched.   Adding some R134a didn't meaningfully change the low side pressure. And that's when a lightbulb flashed upstairs. While I consider the car "old", it's possibly "new" enough to have a variable displacement compressor. Did some reading and sure enough. Dangit. I don't work on these for this reason.   Adding refrigerant means the compressor will just compensate and won't really change pressures until it's severely overcharged or undercharged. But at least I wasn't getting ice/frost anymore, but instead high 30 degree temps out of the vents. That's more normal, but with variable displacement now I have no idea where my charge level is at. It's probably overcharged now. The high side even with the engine radiating serious heat was never really over about 225.   The static pressure at room temperature is dead on, before and after the charge. Both high/low equalize after some rest.   I'm thinking I'll need to take it to a shop. I want the proper charge level so I'm not working the compressor too hard. The only way to get an accurate charge is to evacuate and then re-charge with the exact amount specified for the system -- at least that's what I'm reading.   Anyone here with modern automotive AC knowledge?  
    • Mine is in the shop for the AC now. While it did get cold after a bit, it would take a while to even start to cool the air at all. Turns out the compressor was bad and cycling. 
    • I call B.S. when I first moved to Texas my first house would only cool to 80 with the Texas heat. The AC tech said it was normal at 100 degrees outside. I remodeled the house put in a new AC. I could hang meat. My cars may need recirculating to start. Once moving it switches to regular AC and I could hang meat. Living in Texas no one would put up with only 20 degrees difference. 
    • AC in home or auto only cool down 15-25 degrees from outside temp, but what will help is to put the ac in recirc mode this will recirc the Inside cabin air rather then trying to cool down the outside hot air, I always have mine in recirc mode.
