Try checking your earths first....

Also are you running your power wires away from your RCA's ....if not run them down opposite sides of the car....

What type of gear are you talking about...new items or older amp..

Make sure you have only run a short earth wire to your amp not a long one with the power wire...

sorry, i m a newborn in audio...
what do u mean by RCA's??
sorry for that stupid....

Its alternator noise most times when this happens,
Ground your amplifier, in other words make sure u have sufficient contact for the negative with the chassis. sand paper the paint where you screwed the wire to the chassis for more contact.

RCA the wire with 2 separate insertion things at both ends that connect from the headunit to the amp >< .. red n black one usually

n when sanding the paint back you need to sand it down to the metal so the ground has full contact

where you located? can point you in the direction of a store for you to visit, sounds like your not up to the job of fault finding

[billysch]

so..
what i got is.... the ground one is not fully contact in order to have that alternator wired sorund?

[STARTSat7]

step 1 = check if your (EARTH BLACK GROUND) cable from the amplifier to the chasis is nice and tight (also might want to check that it is in contact with bare metal.

step 2 = if you RCA's (the two cable's coming from you deck to your amp) arnt running through the car along with your power cable (BIG RED ONE FROM BATTERY +)

step 3 = if both steps have been completed and noise still there. purchase urself a noise filter you can get from autobarn etc that plugs into your amp which should do the job.

if all 3 dont work and your located in west syd i can help you out =]

[billysch]

thanks STARTSat7
i think the problem should be step 2...

THanks all

Run Battery Cable
&
RCA Cables down each side of the car Seperate.
Will do the job

I found on my previous setup, that front speaker cables (same could be with any audio cables) were running close to ECU/ECU wiring unprotected, and it was interfering in the same way.
hope it'll help

[billysch]

i have seperated the power cable and RCA by opposite of the car
and the ground one is also well contact to the chasis
BUT .... the alternator sound just not let me go.....still here
PLZ HELP~~
