just finished fitting a new system
RS400 - Reference Series 400W Amplifier
ZX654-100 - ZX Series 6.5 Component Speakers
Kenwood KDC-X 897 head unit.
I am very happy with the whole setup and it is pretty good sound well IMHO anyways

But there is one annoying thing.
What sounds like feed back or interference, a real buzzing .

Any ideas on where to look or what to change?

Appreciate any help
cheers

Spoke with Mike at HW and as suggested above switched to Hi level inputs and now it's perfect.
Thanks for the suggestions.
cheers

yes exactly, Mike explained that some after market head units have a poor earthing arrangement and the best way to resolve it is by using speaker inputs

Not sure but this was what Mike advised me
"Most aftermarket radios tie the minus (-) side of RCA connectors to ground in the radio, which is also tied to the chassis ground of the bike (a terrible basis for ground). However, the speaker output minus (-) wire is paired with the positive (+) wire and isolated through the amplifier IC, making it a true differential output that’s not connected to ground. 9 times out of 10 this will cure your problem."
