I'm assuming that the hissing is coming from the DC-DC step down converter?? I've seen recommendations to put it into a Faraday cage to reduce the radiated noise.
Cheaper options :LOL:
Unsinkable CT: https://amzn.to/4j6WEr6
Or get both of these!
1:32 diecast model: https://amzn.to/3XyaoTk
Levitating display: https://amzn.to/3XXPoFx (this may not be able to hold up the 1:32 model, but a Matchbox version of the truck should work too!)
The CaraokeMic works on all models (I don't know if it works on legacy S/X).

Hopefully you're not wrapping the truck. I've heard the covers potentially messing with the wrap, especially colored PPF. Here's a review of the Tesla Cover that I found on this forum: https://www.cybertruckownersclub.com/forum/threads/cybertruck-oem-car-cover-installed-review-photos.31000/...
