I think it’s on the first or second page of this thread.  It’s on the amp. Plug on the driver side. 

Still can't find it haha, I'll just keep looking. Thanks for your help squeak

I have been unsuccessful in searching where I should hook my power wire up. This is the battery from a 2017 silverado. They have changed it up. 

 

Any ideas?

Im going to attempt to do an install soon on my 14 Silverado with no bose. Im new to all this stuff but from what im gathering, ill need something to convert the signal coming from the stereo. Will this work?

also, where am i tapping this device into. Some say the front speakers and some say the rear. I dont want to lose any volume or clarity out of my front speakers. Thanks

I used a lc2i and highly recommend it. It works great and the accubass is awesome since factory radios turn bass down to prevent speaker failure. I tapped into my front speakers on the plug behind the screen. I just ran speaker wire back behind the rear seat where it’s mounted. Power wire was ran through the grommet on the drivers side. I grounded it on a rear seat bolt also.

Nothing. It just intercepts the signal and uses it for the lc2i.

Where did you install the converter? I notice it needs a power supply. Did you piggy back off the amp and run speaker wire from the headunit back to the converter?

That’s exactly what I did. I just jumped the power wire from the amp to the lc2i. Lc2i is sitting on the floor behind the speaker box.

I finished up my install today.  I highly recommend running a remote wire from the driver side under dash hardness as described earlier in this thread.  Using the speaker level inputs for the lc2i mine would come on but not go off without a big delay when you killed the key and opened the door. 

 

 Now with the remote wire installed it works perfectly.  

 

I also changed my ground.  The seat bolts were a pita so I did some sanding and used the jack mount (back bolt) to ground everything.  It also seemed to take care of some clipping issues I was having with my amp when it was hitting hard. 

 

I messed with the lc2i but ended up turning it down and removing some distortion.  

 

I also installed my amp steps today. That was actually a very easy and straightforward install. Aside from the time it took to solder everything vs using the crimp connectors I went very smooth.  Getting the sliding bolt holders on the rails lined up with the brackets was a tad tricky by myself. 

 

Overall a good day for the truck.

Does anyone know if 17’ is enough power wire to run from the battery to the rear seat in a crew cab?

It depends on the route you take.  I have a double cab (a few inches shorter than your cab, obviously) and I ran power from the battery across the engine compartment, through the firewall and along the driver side and back in behind the rear seat to the center of the cab where the amp was.  I ran a 20' wire and had a couple feet left over.  This is a bit of a guess but 17' is going to be close.  I think it would work.  That said, I'd hate to do all that work to come up a foot short so you might want to do some measuring first.  If you go straight back from the battery along the passenger side, you will have plenty to work with.

Thanks for the reply. Ill just try to get a 20’ cable. Thanks!!

Please post pics when you're finished if you don't mind.

 

I searched all over for something to go in a double cap that would give me a sub enclosure AND storage but came up empty.  You can get dual subs or you can get storage that spans the entire back seat but not half and half.  I ended up building my own - something I haven't done before.  The box turned out great and I'm happy with the sub's performance.  The carpet (I also couldn't find any brown that matched the cocoa/dune interior so I just went with gray) looks a little sloppy but you can't really see it once the box is installed.

    • 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
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
