Ok, i have some blue indiglo gauges for my 5th gen.
I noticed that when i have them on(lit up) and the stereo on they make a high pitched buzz, like on an indiglo watch.
With the stereo off the noise doesn't occur.
Having the head unit on even if its muted causes them to make this noise.
What gives? How do i fix it?

 

which wire did you splice into to hook up the indiglos?

 

i ran a power wire to the right headlight fuse so that the gauges come on when i turn on the lights

 

I don't think the stereo is making the indiglo buzz... but probably the other way around. The indiglo is making your stereo buzz. You probably have amps hooked up to your interior speakers and the high current indiglo module is emitting EMI to the RCA cables leading to your amp.

See if your RCA cables are running under the driver's side dash. If so, you may need to relocate the indiglo module higher in the dash and towards the driver's side a-pillar.

 

please stop... get out, shew :sprays insect repellent:

 

yeah, its youre wiring. who did the wiring?
for me, when i turn on my head unit, its a quiet whirring/buzzing noise.
but when i turn on my hids or ac up, it gets louder and increases with rpm. 'engine noise' or something like that.

maybe wrong tho.

 

you got it man, i forgot to say it increases with rmp...
But in answer to the other guys i ran all my wiring and the rca's are on the other side of the car.

Then, it would happen even if you didn't have indiglos. Check and make sure you didn't run the power cable to the amp next to the RCAs.

 

I did run the power caple next to the RCA's, but the noise only occurs when the gauges are on...
when the lights are on. So its not just the stereo its a combination of the two

 

Relocate the RCAs to the other side of the car and the noise will go away. That's a 'Textbook' Mickey Mouse amp install.

 

my indiglos make a buzz noise too but its when the car is turned off its like a setting...the higher the noise is, the brighter the indiglos get...its liek a warning noise or something. I dunno maybe thats what your hearing.

 

agreed.

 

has to do with the RCA cables, i had the same problem till i guted my trunk. Also make sure the metal RCA connectors arent touching any type of metal behind the head unit as this will cause weird noises and feedback to come out of your subs/speakers.

 

Thanks guys, ill check all of that.
