Please, feel free to flame me. It’s late and I’m calling it a night because I’m sure I’m missing something simple.  

 

Started installing the Kicker subwoofer it from GM tonight.  

 

Ran the harness tonight, connected (without fully installing the box), connected and had sound.  Disconnected and put the box away for the night.  

 

 Two questions:

 

1) ended up with a check engine light (P25A2- engine electrical / chagring system & C0580 - Traction control error) after everything was run.  OnStar says there’s a charging system issue.  Anyone else encounter this?

 

2) Rear door speakers have nearly zero sound. Extremely low volume, and extremely light sound (zero bass, almost all highs).  Fronts sound fantastic. 

 

Sorry and thanks in advance for the help everyone. 

You should check your battery connection at least in 2 places...

1.  Did you re-seat the negative battery correctly and tighten it

2.  Did you wire the Pos line to the right fuse set?  See My Pic.

 

Third thing is did you splice into the correct wires on the passenger side or damage one while removing the insulation?

Looks nice.  I modified my storage to fill in the rest of the space.

I'm looking for a sub tap or high level speaker tap to add a sub amp to a non-Bose system.

The kicker instructions mention the brown and brown/blue wires at the audio control module.

Does anyone know if this is a low level sub output or a speaker tap?

Thanks in advance.

Did you have to remove any of the console to get the wire in there?

No, I used a metal coat hanger from the rear to pull the wire through.  You can pull the charger pad off for more room.

Can you confirm how you tied into Bose system for signal to your amp? Sorry if you already explained. I ordered LC2i module and thinking to get signal from front door speaker wires in wire harness by passenger side front?

If it’s the same as the 14 to 18’s driver side kick panel you tap off the rear driver door speaker wires. That’s how I did it when I installed my Kicker sub. I have Bose but it don’t matter Bose or not. There braided wires just cut back the harness tape and T tap them.

JL Audio makes a Stealthbox with 2 subwoofers, not cheap, but looks really nice and sounds amazing.  I ordered one, should be here next week or the week after.

Had mine installed today, wasn't very smooth.  Went to the dealer where I purchased the truck and subwoofer - they have an off-site customization center affiliated with the dealership.  Quoted 1 hour.  Took them 4 hours, and they wanted me to pay for the extra 3 hours.  I refused and they finally relented, kudos to them for doing the right thing.  

 

Driving away, I noticed none of the HVAC or seat heat controls were operable.  Turned around and went back 5 mins later, sat around for another hour, until they asked if I had messed with any of the trucks wiring.  When I said no, they then wanted to send me to the dealership next week for diagnostics.

 

I quickly Googled the issue and recommended they disconnect and reconnect the battery.  That did the trick.

 

Sounds good, glad I had the remote installed too.  For anyone else going the dealer route, might want to make sure they have done one before, and definitely don't commit to a time and materials approach.

I played around with them and ended up with 1,2,3,4,5 in the up position, 6 down.  It's pretty loud, but with the control knob you can dial it back. 

 

The best crossover point seemed to be 1up, 2down, 3up (4up,5up,6 down), but the volume was too low.  One of these days I'll figure out the sweet spot!

 

Talked to Kicker, 1,2,3 = Gain Settings, 4 = 12volt or DC (leave it up for 12v), 5,6 = Slope  (5up and 6down = 12db), not sure what 24db would be.

    • 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.
