the xv amp doesn't need the LC2i. I believe the rear speakers are the ones to tap into on the newer systems. 

 

 

Thats one reason i stepped up to the VX amp is so i wouldn't have to mess with the LOC or nav tv.

The VX amp's input is essentially the same as an LC2i, LC7i, or any other LOC, the only difference is that it's integrated into the amp. But if the installer wired it wrong, either chose the wrong wires or hooked them up incorrectly, as Jon suspects happened in his case, the VX amp wouldn't change anything.

 

Personally, I'd prefer to keep things like an LOC separate. I know it looks cleaner without having a bunch of different components wired together, but when everything is integrated, and one section has an issue, it takes the whole system down and is more costly to replace. Say your LOC goes down, if it's integrated, you're done, replace the whole amp. But if it's not integrated, all you need to do is replace the LOC, and whether it's a cheaper passive unit or a powered unit like an LC2i or LC7i, it will still be cheaper to replace than a VX amp. Just my $.02.

Would you consider selling the stealthbox separately?

Update about my NAV-TV experience in 2020 AT4.

 

I finished a complete install a week ago.  Components in the front, coaxials in the rear doors, AudioControl D-4.800 amp for mids/highs and AudioControl LC-800 for subwoofers.  I was going to wait until the NAV-TV unit was updated until I installed everything, but I got tired of waiting and went through with the install.  I bought the NAV-TV unit in December, and I did not update it.  It came straight out of the box and I installed it in my truck.  It has worked perfect without cutting off.  I have had zero issues.  The signal from the unit is perfect and the output sounds incredible.  Everything can be tuned perfect with the built in DSP in the AudioControl amp.

 

I am not an expert but it seems like certain amplifiers are causing the problems.  I am not sure if it is an overheating issue or the unit going into protection mode (if it has one).

I am not an expert but it seems like certain amplifiers are causing the problems.  I am not sure if it is an overheating issue or the unit going into protection mode (if it has one).

Going by my experience in car audio, roughly 30 years doing all my own installing up 'til the last couple installs (can't bend like I used to) there are a few reasons for an amp cutting out.

 

First is wiring (either an issue with power wiring or speaker wiring). There can be hard shorts to ground that take it out immediately (blowing the fuse) or intermittent shorts that happen during movement, which happens quite a bit in a vehicle. There's also shorts between the two leads going to the speakers.

 

Next is too large of a load connected to the amp (wiring the speaker load beyond/below the amp's limits). Some manufacturers are conservative with their amp's spec'd limits. That way if the customer does go a bit beyond the amp's limits, it will still work properly, acting like a buffer.

 

Too high of an input signal could also cause an issue if it overloads the amp's input stage. It might blow/overheat an internal component. Or if the input stage can handle it, the signal might be clipped, aka distortion, which can take out the output stage of the amp or overdrive the speakers. That can lead to a blown voice coil or cause the speaker cone to extend beyond it's mechanical limit and get high centered on the pole piece.

 

Then there's inadequate ventilation for the amp. An amp needs space around it for heat to be wick'd away. This can also apply to amps with built in fans as the need space to blow the heat away from the amp. This is a big issue in vehicles when amps are mounted under or behind seats where there may be little to no ventilation. My installer suggested mounting my amp behind the rear seat, but I'm not ok with that as there is little to no space around the amp back there. And if you run an amp hard it's going to be an issue. I'm guessing that may be the reason for most of the people on here having this issue. It could also explain why one amp had the issue and another doesn't, since some amps either don't run as hot or have better built in ventilation than others. Having no ventilation also causes another issue in that it will heat up the surfaces around it, which then reheats the amp in kind of a cascade effect.

 

Lastly, it could just be an issue with the amp's internals. For example, if it has bad components in the power or amplification stage (bad transistor or IC) that could also cause it to have an issue. The only real way to know if this is the case is to swap out to another amp of the same model and see if the problem is still present. Of course if both amps came from the same batch, it's possible they could both have faulty internal components.

 

I've seen all of these issues before, either on my own installs (bad internal components on a couple), or those of friends, even stories from installers. The key to finding out the culprit is methodical troubleshooting, trying to isolate as much of what you can, to narrow down what's in play. For example, try running the amp with no speakers hooked up and see if it still shuts down. If that's ok, you've probably eliminated the power wiring. Then hook up the speakers but keep the volume low, that should help eliminate speaker wiring and possibly tell you if the input signal is too high or not. Or if you're using 2 subs only hook up one and turn it up, that should tell you if you have too big of a load on the amp. Lastly, try to move the amp to a better ventilated area, like just sitting on the seat or the floor, that should tell you if it's a ventilation issue. 

 

Those are simple troubleshooting steps you can take, but some aren't 100% foolproof. It could still be a power issue that only appears when the amp is being used at full capacity. But eliminating as much as you can before talking to manufacturer tech support will save you time on the call, and doing it before taking it to a reputable installer can save you money. Just my $.02.

I’ve been in touch with NAVTV (Mine has been shutting off) and here’s the explanation.  The early units had a part that wasn’t what they originally designed bc the supplier replaced a chip with one the supplier thought would work the same but apparently didn’t.  This means it’s a hardware problem.  They shipped me a new unit which I plan to install tomorrow then send the original unit back to them.  I’ll let you know how it turns out but they say this will solve the problem.

Does your NAV-TV unit turn completely off or did the volume drop and have a staticky signal?

Actually both, more often drops the volume but sometimes when I reset it there’s static when it comes back on.  I got the update and that made it happen less often but still happens

I guess I talked to soon about mine working perfect. Been working perfect for over a week. Hours of run time and this afternoon the volume dropped pretty low and it had a staticky signal. It was in and out on the 15 min drive. Hope they will replace mine also.

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
