Kicker tailgate audio

SCottCo · July 30, 2020

I recently installed the kicker tailgate audio system. I got it through GM parts direct. Installation was fairly easy. The system worked fine for a while. It stopped working one day. I believe it is tied to hooking up a utility trailer. Hasn’t worked since I hooked up for the first time. I contacted kicker and they actually sent me a new system. I’ve installed that, It’s still not working. It does not seem to have power. I’ve checked and double checked all connections. Seems like I’ve blown a fuse. Does anyone know what fuse would have blown? I’ve gone through the fuse box and don’t see any that are noticeably blown. I’ve heard of people hooking up their trailers on newer trucks and having a short in the trailer wire. This will blow a fuse. I’m assuming the kicker system is on that same circuit. Any help would be appreciated.

Grab a volt meter and check for power at your trailer plug receiver. Chances are, you will have an extra wire with no voltage. (the ground being the other wire) Chase that wire down and see where you lose power.

Thanks for the response. I’ll try that. Do you think there’s an additional fuse somewhere in the line? I went through every fuse in the box, and they were all good..

I own a 2020 GMC Sierra 1500 AT4. In a previous post I described my kicker audio tailgate system stopped working. I think it’s directly tied to hooking up a utility trailer about a month ago. I think I just simply blown a fuse. I have gone through all of the fuses under the hood. I just recently discovered the two other fuse boxes in the cab. I can’t believe I didn’t know they were there. Is there anyone on here who knows which fuse runs the kicker audio system? I assume it’s the same fuse that runs something in the trailer hitch.
Thanks

Just had the very same issue on my 2021 GMC 3500 after towing my travel trailer.

The local GMC Dealer traced it to the 30 AMP fuse in the block under the hood.

Fuse part is 22917202 (large 30 AMP fuse)

Fuse circuit is No 63 (TRLR BATT)

Kicker Stereo works fine now but let’s see what happens when I hook up my trailer next time?

I’m sorry, I know this is an old post. Any resolution to kicker not powering up? Have you located a fuse? I recently towed a trailer but just hooked up and all lights work. Could it be mid gate switch not telling truck it is open allowing for power to kicker? Thank you so much for helping in advance

There is a fuse right behind the rear license plate for some reason mine keeps popping and the kicker system stops working.

This happened to me too. It turned out the installers did not fasten wire under the tailgate covers. Wire kept rubbing on one of the hinges and exposed wires and kept shorting itself. Take the plastic covers off (use T30 and T20 I think) and follow wires.

90 percent of the time its a blown #63 30 amp trailer fuse

I have had this issue for a while and just now found out my problem. It was the 10a fuse behind the rear license plate that had blown at some point and filled up with a bunch of corrosion. Going to have to work on that tomorrow.

If your tailgate system stopped powering up. A few things to check. If you have recently connected a trailer to the 9 pin trailer plug. Check the fuse under the hood for the constant 12v power to trailer. If it is good there is a smaller fuse under the truck around the rear licenses plate. If all of them are good. The next thing to check would be the position switch that senses what position the tailgate is in. To test you will need to remove the cover or baffle. once inside the gate make sure it is opened to fully so you have to have the second gate open also. Then check power at the amp. If you have power it could be a bad amp. If you do not have power its the position switch. Once you figure that out its simple to fix. Your system if purchased through a GM authorized dealer you have an incredible 3 year / 36k mile warranty through any GM dealer in the country. Even covers the labor under warranty.

I have a 2500 denali with same issues. 30a fuse under the hood was blown, replaced but still no power. Where is this 10a fuse located behind the license plate? All i see is a schneider box/sensor thing.
