I have buzzing coming from my front left tweeter and a very faint alternator whine. I have narrowed it down to the rca’s coming from the my gs9. I have tried to run an extra set of rcas over my seats trying to see if that would get rid of the buzz by keeping it off the vehicles floor, unfortunately it gets worse. Any ideas of what to do here? Driving me crazy!!

Its been going on, but it seems to be getting worse. I dont understand why when i run the rcas over the seats the buzzing gets worse, this is the first time i have ever had noise issues but this is the first system i have had in my tacoma as well.

The hum could be through the RCAs or through the ground wire, or through the power wire.

How do you know it is coming in via the RCAs?

I just thought thats what it was because I unplugged the rcas from the amp and the hum was gone, so that eliminated the amp and everythibg in front of the amp going to the speakers. Then I plugged the rcas back into the amp and unplugged the rcas from my sony gs9, the hum was gone so that rliminated the deck, which left the rcas from the deck going into the amp as picking up the noise, its driving me crazy. When I add put my jl vxi amp i am going to hook it up optical and rca. I want to get rid of this damn hum!!!

Finding the causal mechanism is usually not very easy...

A ground loop usually has the appearance of a loop somewhere.
And that loop gets broken when the RCAs are unplugged.
(If you had removed the + and - and sat a spare car battery in there to power the amp, that would also break the loop.)

The RCA to 1/8" and 1/8" to RCA can be handy.
The first (female version) can allow for headphones to listen to what the RCAs are presenting.
The second (male version) allows an iPhone to play music into the amp.

Ground loops are hair pullers for a lot of people.

I'd be tempted to also use a 1/2 set of jumper cables and try seeing what attaching the ground does?

But you are on the right track with the secon set of RCAs. Try moving them closer to the power wire and see if that changes things. It doesn't matter if it is better or worse, one just starts "devining" where to go.

Yeah i am gonna work on it this weekend. Do u have other suggestions to try? Also what do u mean by a ground loop having the appearance of a loop. I dont want to have to use optical all the time because I like using my volume controls on my steering wheel. I dont know how i could have a ground loop either, i use one main ground and the rest of my grounds go to my audison power/ground distro box. I actually put an extra chassis ground on my deck as well. I just got to get rid of this buzzing/ground loop some way.

If the installer did the install and it just happened? Take it back to the installer and have him fix it. Just my 2 cents. :)

Also, some of these amps don't filter the power so it can bring back in noise in the audio chain. There is a reason why I like some of the amps. Even the Stupid BOSS armor series. At least they sound good. Even if the installer sucks MASSIVE HORSE .........Yea. :)

Another thing to check out? Have you changed spark plugs or wires? Is your Alternator still in good condition? If one o the diodes start leaking, it can do the same thing. I just wanted to throw that out there. You would not think spark plug choice would make any difference,.... But boy... That was a FREAK thing that I experienced when testing out spark plugs.

So please check the grounds in the engine bay frist, plug wires, spark plugs if you can't find the issue at the amp install.

The truck is brand new pretty much, the amp is s mmats hifi 6150d and just got returned from mmats with some upgrades done and a clean bill of health.
My installer has always done a great job, but i believe I might let him take a look at it again
