Im going crazy....

[LinkinX]

I just got done amping my speakers and adding subs. Turned it up, jammed, listen to it low and sounds great-

Until the car is running, there is a high pitched buzz from the speakers that gets louder as you rev the engine….

Anyone have any ideas?!?!?!?!?

To try to find the issue I will tell you everything I am running and things I have tried.

Deck, stock (non-Bose, mazda6)

4 Alpine speakers’ 2-TypeS, and 2-TypeR

Powered by a 4 channel alpine amp (MRP-F240)

2 Kicker-comp subs

Powered by a Audiobahn A8000T 800W Mono

Both amps are using the high-level input option.

And the remote is off a cigarette lighter for now.

I have tried separating the power lines from the speaker lines

I have grounded to the bolt that holds my seats down,

Also dilled a new hole, took off all the paint, and shorted the lines.

I have taken out the subs (still out b/c they make the noise a lot worse)

I also added a new ground line in the engine bay

The main thing that seems to bug me is, it ONLY happens when the car is started. So it would have to be the engine or alternator or something idk…

Any help would be appreciated…. I can’t stand the noise…. Going crazy lol
