I installed my light bar a week ago and I haven't noticed any Hiss sound from the speakers. Ordered from Tesstudio. I also just installed the power running boards from Tesstudio and run into a problem. Both accessories Tie into the BUS connector in the dash on the passenger side. I'm not sure you can stack these together. Because I get an error on my Frunk power switch (Where the running boards tie into). SO they are not working at the moment. And so far Tesstudio has been hard to reach regarding this issue.

Watching this as my steps are here at the house I also have the lower light bar installed and wondered about this but they said it would work so to hear yours isn’t working definitely concerns me. Truck is current at Tesla getting the upper lightbar installed.

I've done a lot of research on this and I think we need a BUS splitter or Y. Because daisy chaining both of these in between the factory plug I believe is causing the problem. It is not affecting the light bar, just the steps.

generally agree with your assessment, but not sure if these companies will be sending anything like that any time soon.

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.

Tesstudio. I think several of these companies are the same people, or drop shipping websites. The instruction manual for the power running boards from Tesstudio has a link at the bottom that links you to a competitors website. :rolleyes:
They told me the parts needed was some screws, is that what you where told in the email?
