Speakers Whining...., Alternator whine / turbo.... Options

[Cs91]

Okey, here's my problem.
I got a pretty big audio installation in my 96 ST. The thing is that my speaker keep whining, even if the engine isn't running. And it only gets a hell of a lot worse if I crank my engine. If the engine is going the whining follows the rpm, so when revving my engine, it gets pretty loud.

Done so far (tips came from Norwegian Audio forum):
- I have grounded my RCA's to the battery.
- Grounded my Head unit to the battery.
- Grounded both my amps to the battery instead of in the chassis, done with 35mm2 cable.

My setup:

Dynabel BF0804 ( 4 channel providing my front and back set)
Dynabel BF7501 ( 1400W running my 12" in the back)
Headunit: Boss BV9995
Have done the "big 3" in the engine bay.
Seas Lotus 6,5" 3 way system with 1" tweeters in mirror houses. ( Specs if searching for Seas reference)
In the back i got some Pioneers, dno model atm.
12" Dynabel DY9812 (30kg heaving bastard at 1000W RMS)


Would love some help, or just a saying that it could by my Head unit that is defect.

You're running the RCA lines too close to your amp power line, which is causing the noise. Separate them and you won't have a problem.
