Kicker tailgate malfunction?

I have almost 500 miles on my new truck. Yesterday I unfolded the tailgate to try the stereo out, then realized I’d left my phone in the house. I went back to the house to grab my phone and, as I walked back to the truck, I heard a loud popping/shorting sound coming from the tailgate speakers. I tried turning the volume down, but no effect. The popping continued intermittently. (It sounded like the volume was way up while somebody kept connecting and disconnecting the speaker wires.) I tried to pair the kicker to my phone, but holding the Bluetooth button down never put it into pairing mode. Basically, the system was totally unresponsive to everything I tried but the power button, so I turned it off.

Any idea what is happening or how to fix it? The dealer is 100 miles away, and their service and parts departments are weak.
My experience with my BT tailgate Kicker system... it has NEVER WORKED. It was down when I test drove the truck (bought preowned in DEC of '23 w 16k miles) and I bought the truck anyway. GMC has had an open ticket since Dec - the day after I bought it. GMC blames kicker for a lack of available parts - amp if fried - keeps blowing fuses. that's my experience. We'll see if it ever works but I am not optimistic based on my experience thus far as well as those around this forum.
 

I noticed the driver's side speaker on my Kicker system would go in and out. I took off the faceplate and crimped down the two wires connecting the speaker and all is good now. We'll see how it goes...
 

Tailgate Kicker system: Looking back soon after I got my truck, the tailgate speakers crackled. Rather than take it to the dealer where I was complaining about other issues, I recrimped the speaker leads and it has been working great since, connects to BT very quickly and sounds 'ok'; its not hi-fi but for a tailgate system I rarely use except when cleaning the truck in the garage, its ok.

I'm willing to have the sunroof to get the superior ride. The multimatics are night and day different to the regular AT4 shocks on normal roads. That said, maybe not all AT4X are made the same, as I know PineBaron completely disagrees that the multis are any better. But in my experiences driving 2 different AT4X, it is so much smoother than a standard AT4 2500. The other huge upgrade is the seats on the AT4X. So those 2 upgrades are well worth having a sunroof and the ridiculous tailgate audio for me. I also think the black bumpers, especially on Volcanic, elevate the look of the truck big time.

My dealer has now sweetened my numbers even more. So I am re-tempted. It is getting close to Rivard numbers now, with an over value on my trade and without the extra dealer fees. But the money is not the issue for me, it is being bugged by the gear shifter.
Yep, not digging the gear shifter. It's just in a bad spot and the fit and finish don't match the rest of the truck.

Truck inventory of every flavor is accumulating on dealer lots. The prices are ridiculous, and many people finance trucks, so the high interest rates have compounded the sales challenge. People also WAY overpaid for everything when COVID limited supply, so many are upside down in their trades. The combination of these influences and concerns about the stability of the economy has suppressed sales, so inventory is stacking up. (It has crushed sales in the RV industry.)

I’m old enough to remember several cycles like this. When we’re in a period of supply not meeting demand prices soar and trucks are hard to find, but all we have to do is wait, as the manufacturers will always exceed demand within a few years. When that happens we always see increasingly aggressive incentives in the form of rebates, subsidized finance rates, and “customer cash”. More of all of the above is on the way. (When GM/Ford/Stellantis throw another $5K per truck at the dealer, your offfer can improve on both the trade side and the new side of the deal.)

If seat design and ergonomics are important to you I strongly recommend test driving a Ford Tremor. Lower the tire pressure to 50 psi. Tremors come with the HO Powerstroke, which is fully 20% more torque than the Duramax. The ride is rougher than the AT4X when both are driven empty with max air pressure in the tires, but the new Tremors will run 37” tires without any lift on +12 offset wheels, and running those tires at 45 psi produces a better ride than my AT4X. When carrying heavy loads with tires aired up on both trucks the ride is very similar. The superior seats of the Ford make a big difference. The GMC turning radius is tighter. The GMC sunroof is less irritating (for me), as Ford sticks you with a whole-roof sunroof. If you enjoy adding accessory lighting, radios, suspension, etc, there are many more options with Ford, and the Fords still come with 12 volt outlets, 120 power, and upfitter switches with fused hot-leads inside the cab and under the hood (although, in keeping with the rule of changing things they had right, they have made the latter much harder to access.) The Tremors also have nearly twice the payload of my AT4X AEV.

As always, every choice involves a trade of some kind. They’re both great trucks. Both have stupid, irritating, features. For me, the list of stupid irritations on the Ford is shorter, but the 2025 Fords are more irritating than the 2024s. (For example, for 2025 you have to get the fugly Platinum grill in order to get leather, as it’s no longer available with the Lariat Ultimate trim.) I don’t know if that’s true of the GMCs, but all three manufactures favor making changes with every model year: it doesn’t seem to matter if the change they’re making is an improvement, so I’m always anxious about what comes next.

I should have checked back on this thread a long time ago. You’re right. Recrimping the speaker leads eliminated the crackling/cutting problem. When I last checked, the tailgate system was working fine, and the quality is just as you describe it.

For my two cents, I would have preferred GM to skip the tailgate system and put the extra investment into the stereo inside the truck. That probably would hve been enough to elevate the stereo to mediocre. If the truck stereo was decent you could achieve better sound by just opening the doors and windows and playing music that way. For prolonged listening, like a barbecue, for example, the sound quality of the tailgate system is easy to match with a couple of outdoor bluetooth speakers — and you can sit those on the tailgate or take them with you on the boat/beach/4-wheeler, etc

The good thing about it is because it's there I don't have to lug my speaker around. My Bluetooth speaker sounds far better and louder though. Honestly if they had invested the money into the four window switch and simply made the windows go up I would've been happy and not missed the Tailgate speakers .

A quick software reprogramming would do it; shame we don't have the code and truck is too new to send it to code breakers :)
 

Yikes, I don't think I'd care about a tailgate speaker vs the massive upgrade in shocks you get on the at4x, not to mention massage seats amd the bumpers. The tailgate speakers would be the least of my concern.
I think it was clear I was referring to the lack of individual options and my need for no sunroof.

Agree 100%
 

I actually enjoy the GM sunroof. It’s a simple 1980s design and they don’t tend to leak like the Ford “panoramic” sunroofs do. They don’t heat up the cab as bad either.

I can take or leave the massaging seats. My wife loves them, but I’ve had them in three vehicles over the last six years, and I doubt I’ve turned them on five times. The cost of the massaging seats is less comfortable seats when they are not massaging, as least in the Jeeps and GMCs. Massaging seats feel seats feel harder and less contoured, probably because there is so much hardware right below the surface. My wife disagrees but, for me, the massage feature is more gimmick than benefit. (And yet, we have them on the Ford too… Happy wife, happy life.)

The shocks on the AT4X are great. Having said that, I’m confident they could be matched (at least) by some custom-valved King shocks.
