Check your ground first, if you do not have a good ground the amplifier can be looking for ground along the RCA path. If that doesn't do it, try changing to a different speaker, to see if scratchy-ness continues. If it does continue and you can eliminate the speaker, try changing RCA input by swapping to a different output on your radio. If it STILL continues it would be something inside the amp itself.
