Denali subwoofer and amp install 2022

[JohnnyFamous]

Much thanks.

Where is your remote wire?

I did not use one. I contemplated it but was trying for a simplistic install with as few wires as possible. I did try and locate a remote turn-on in the fuse panel, but the panel is 100 percent power all the time, or at least I couldn't find an ignition/stereo timed turn on in it.

The ACM amp has a GTO signal sense built-in and detects if there is a signal to the amp and will turn on. I was a bit skeptical but have confirmed the amp shuts down when the truck is off and works perfectly. It appears to be a really well-built AMP.

Great install and I really appreciate the research you've done and results you've shared. I'm adding this to my wish list for my 22 Denali. I've never installed an amp/sub before so I've got some more learning to do before I tackle this.

Did you add this sub in parallel w/ the stock one (if we even call that a sub), or did you disable the stock sub? Can't tell from your pic if you cut the input to the stock or not.

It is not used. I cut the supply to the sub to grab the high-level input. I would not leave it connected.

Can you post more detail about where/how you tapped into the high-level input? Thanks!

You can see the sub in the photo; where I cut and spliced, the green line goes to the new amp. Yes, it is an old Christmas extension/lamp chord I had laying around, I have read a lot on fancy speaker wire, and it really only comes down to resistance, contrary to the hype.

I will say I was unable to confirm polarity, took a chance and assumed the black grey was negative. It appears to be firing correctly; I am not sure if the amp would rectify the polarity or if it matters with a high-level input. I played around with changing polarity at the new sub and couldn't see a difference nor tell if the sub was pushing or pulling.

Nice read. Any vids

I assume you ran power from the battery all the way back? How easy was it to find a good channel to run your power. Is there a good ground location under the fascia piece in the compartment you put your amp in?

Thanks for the details!

The Audio Control piece senses input on the high level input… to turn itself on… Audio Control is good stuff / high end brands have all kinds of cool features.

Now that the JL stealthbox is available on the 21+ I wanted to ask you if you ended up DIYing this project or if you found a shop to do the install for you? I think your amp location is clean and out of the way but curious how difficult it was to route all the wires from the battery back. Only thing I feel like my bose system is missing is the low-end bass. That new stealth box is a 400w JL 10TW3 so I think your ACM amp will give me the sound that I want without me having to give up all sorts of other space to put an amp in to drive that JL stealthbox.
