Buzz after wideband - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I just finished installing an AEM wideband and AEM boost gauge in my pillar. Both gauges are connected with an add a circuit to one of the auxillary 20A switched fuses in the fuse panel. If i remember its F17 or F18.

My setup looks exactly like what is mentioned here including my ground location:

http://www.camaro5.com/forums/showth...fuse+panel+tap

I am currently getting a very slight buzzing sound through my speakers. Both gauges are hooked up to the same fuse tap and also the same ground.

The buzzing did not happen until i physically hooked up the wideband o2 sensor to the gauge.

I also have been running a JL XD400 amplifier.

I tried moving the ground to just locations around that fuse panel, and nothing seemed to change.

I also moved my amplifier ground (currently grounded directly to battery), and again no change.

Do i need to find a different ground location for the gauges?
Should i try separating my boost and wideband grounds?
What about a ground loop isolator for my amplifier?

If anyone has had a similar situation, what did you do to resolve it?

Thanks,

I tried grounding the wideband directly to the battery and it didn't make a difference.

Tried ground loop isolators on the rca's for my amp...no difference
Removed the JL amp and put the factory one back in.... no difference

The only other option i have is try running the power directly to the battery, but have a feeling it wont make a diff either.

I talked to someone else on here, and they could never get it resolved either.
