High pitch noise

[Farrie]

Hi all

I just installed some Focal speaker and Focal 4 channel amp. Sounds great except I get this really high pitch noise that comes and goes. It only started when the amp was installed.

The power and earth cables are routed separate and it doesn't sound like engine noise.

Any suggestions??

Thanks!!

I'd like to know what "earth Cables" are!!

More than likely a bad ground or bad RCA's.

They speak a little different down under.

I guess so.

I think the next person that needs help I'll tell him to check his earth cable.

So I grounded each rca cable to the headunit. Made no difference. Was playing around with the rca's today and I disconnect one set and its fine, plug them back in, the noise returns and then unplug the other set and its fine again.

I got no idea!
