wheres the noise commin from?
is it commin from the speakers or under the engine?
i undastand that if amps are drawing too much power from the battery the alternater makes a kind of squealing ish high pitched noise.
I have never heard this so I am unable to clearify this with you.
take it to an ice specialist and have them look it over.
Be careful and make sure you go to a reliable one.
who installed your system?...check all wires...specially the Grounds, these may seem fine but sometimes it may be the cause.
Good luck buddy.

can anyone help!? :(

I'm running 2 amps (ones 300w and the others 600w)they both have got their own power lead running to the battery and ground lead which are grounded at different loations.

When a switch the 300w amp on it runs fine but when i switch the and 600w on it's picking up interference. when i switch my car on it get's louder and when i revv the engine the noise increases in pitch (a bit like a squeel).

i have ran the power cables down one side of the car and the RCA's down the other side, and the grounding are very clean points.

Can anyone help cause the noise is driving me nut's and it's not just a little noise it's very loud.

Thanks
