I have mine working. I had to reprint the parts with PETG filament to make them UV and sunlight resistant. The first ones warped.

 

I wired in a power switch as there are times I will use the system without the tailgate down (for example when camping and I have my hitch in). I also, just ran a standard amp wiring kit along the undercarriage rather than cutting into or modifying my 7pin connection. The 10 Gauge wire was much cheaper than buying the $90 pigtail.

Thats all great and all, but just curious, why go this route vs getting the KICKER system thats avail specifically for our tailgates?

I only ask this because you still only have 2 speakers versus the 4 speaker set up which is posted in OP.

Kicker system ~$600

This ~$150

I am an audio engineer and trust me, you only want the 2 speakers.  One for the left channel and one for the right.  When you put 2 speakers playing the same thing next to each other like that, they actually interfere with one another.  The science of it is complicated but its called comb filtering.  Feel free to go down that rabbit hole.  

The basic principle is you put a speaker where you want sound to be.  If you want more volume, use more power to drive that speaker (as long as it can handle it) and not more speakers.

Well that explains it :) lol

Any pics of how you wired everything up?

I don't, i just followed the standard wiring diagram that came in the box. The amp wires were ran thru the tailgate, above the spare tire, then along the chasis, up along the firewall under the hood and to the battery. I used zip ties to secure the wiring .

The best analogy I can come up with is that it sounds about like playing music through your cell phone speakers vs using Bluetooth through a real radio. You really should listen to one before you buy.

Sorry to OP about the tangent, but had to ask...

 

This is a bit extreme, but some wakeboat owners go nuts with multiple tower speakers.  Would they have an issue with comb filtering?

This looks so cool, can you provide the 3d print files either through thingiverse or yeggi?

I am trying a slightly different approach on this. I have a 3D printer, so I have designed replacement panels along with panels that have recesses for the bluetooth controller and an aux port.

Once I get the marine speakers in, I will print panels that have mounts for them as well.

Actually do you have your 3d model or cad file or whatever you used? I'd like to modify the speaker one to use bigger speakers

Did you mount the amplifier inside the tailgate? If so, how did you mount it?

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      By c4racer2 · Posted

      oh ya that's good to know - I would rather use a gear than the brakes down a long hill.  I would not let cruise control take over on snow or towing a trailer for sure on hills anyway.     The other thing about the CO trip was that was all done above 6K feet for the most part, so that has to use more gas as the motor is down a good amount of power up there.   If I drove my 2016 Camaro with a very similar V8 to this 6.6 it would probably get about 23-24 on the fast run up to NE.  But the premium fuel premium is steep here in CO, so it would still only save about $40 in overall costs for the round-trip.  And you sure can't carry much gear in a convertible camaro!
