Hi, apologies if I'm breaking any rules by asking here. I've searched and searched and found very little info from Google or elsewhere. It may be that I'm not using the correct terms, this is why I'm hoping that someone might be able to assist me here.
Tldr (too long didn't read):
I have an electrical static noise coming from the dash passenger side. It sounds like when a speaker is loosely connected and it crackles.
Details:
The noise began after installing a vibe active sub. The sub already has a hi pass, so I used wago connectors to run a speaker wire direct to that using guides to understand where each wire should go. The install went well, the sub sounds nice. At first the noise was not apparent at all. One week after install I noticed the sound coming from what appears to be the passenger tweeter area.
When it occurs:
It doesn't happen when I blast the aircon, or turn the fans on full power.
It does happen when I'm travelling at over 25mph it gets louder and the tone changes slightly the faster I travel.
It doesn't happen when I rev the engine whilst stationary. It continues if I disengage the gear whilst travelling and release the accelerator.
This all indicates a vibration issue, or an electrical contact possibly touching an earth (I doubt this though as I've not interfered with such and the wago joins I'd tested and were well done). But the sound isn't a vibration sound, hard to tell of course whilst driving, but it really does sound like a badly connected speaker with the wire being moved around (I'm kinda hoping so one will know what I mean by that)
Things I've tried, I have tested for a good earth. Resistance is 0.5, that appears fine. I've disconnected the sub speaker wires (hi pass in from back of speaker out in stereo), no difference. I've disconnected the sub entirely, no difference. I've removed the passenger side tweeter, no difference.
My next test has to wait until the weekend, I'll dismount the glove box and get my wife to drive it whilst I listen to localise the sound. I may also go through the whole stereo removal process and double check everything I've done when fitting the sub wires.
Has anyone got any idea what this could be/experienced a similar issue?
Thanks in advance
