Hey Guys
I need some help here.
I have this really annoying "buzzing" noise that travels through my component speakers. It is coming out of every speaker (2 front, 2 rear). The noise only happens when the car is running, and at which time is consistent with the RPM's from my engine. I have a video below to get the point across...and sorry it was dark...but you can here the noise.

Now this is my setup:
Kicker 0awg wire from the battery- through fuse - to the back of the car - distribution block - Wire 1 - subwoofer cable travelling through capactior - to the amp
Wire 2 - straight from the distribution block to the 4 channel MTX amp.
Now, EVERYTHING is grounded properly with the proper gauge wire.
My power wire is on the left side of the car and my RCA's are on the right side of the car.
The 4 channel amp power wire from the distribution block runs into the amp....coming about 1 foot away from the RCA's...but I mean I cannot avoid that...as they are both going into the amp.
Now I have tried a Ground loop isolator, and it seemed to help a LITTLE bit...but not much so I did not buy it.
My wiring behind the deck is done to perfection and the wires are sawtered (wrong spelling..to lazy to look up lol) and wrapped individually.
What can the problem be!!!! I have tried sooo many things..and each time it is still there.
Any other suggestions.

Do you have a Pioneer Radio? Is it a kicker 4 channel amp, if so what model is the amp?
Yes it is a Pioneer Deck but with a MTX 4 channel amp. I do not have the model I will get it tomorrow if need be? Does that help at all?

Pioneer Deck has to grounded to the batt period no ifs and or butts. it sounds like an alt whine? do you have an alt noise blocker on the alt? and is the head unit grounded to the batt?

OWWWWWWWWWWW you said you discharged the cap!
ok
Now i know that it is grounded through the harness. But I think you mean it has to be grounded from a screw on the back of the unit to the negative terminal o nthe battery? Is that what I am understanding from this? I have also heard of peope running a wire from the ground? on the amp to the back of the head unit?
Where should I run another ground?
I had this exect setup before...just with a smaller wire...but ever since I got 0awg to the dist. block..then 4awg from the block to the amps it has become a problem. Not sure if this helps at all
If I am running a wiring from the HU to the (insert here?) what gauge wire should I run.

just a 18 or 16 the natural size of a radio ground.

you can do it....
advanced MECP, lol does it really matter....
patience is a virtue
ok sounds good
now should I be grounding it both to the amp and to the negative battery terminal? Just want to make sure I am correctly understand where I need to ground it too and from. thanks

The ground wire of your radio has nothing to do with this problem. After you read this page, please feel free to browse the entire site, It only has a few pages.

may not be this problem here but id still ground it to the batt anyway . Pioneer head units are known for ground issues.

OWWWWWWWWWWW you said you discharged the cap!
You are right, they are known to have ground issues. And they are ALL related to the RCA jacks.
