stereo humming where to start?

Thanks guys I will give Jaycar's a ring tomorrow and see if they have one. Will I need to loop the ground around it as well; if yes I will get a bit more extra cable tomorrow as I think I said I was a little bit short to make it neat?

Done some surfing on the net. Thus far I have a couple more things to try. The ferrite rings being one, which they did not mention. Tommorow I am going to change the 10g + cable to 8g and wrap it in conduit as suggested on another site. I will also get the ferrite rings. Failing that I am going to chat to Autobarn and complain because if the former does not work then the amp is obvoiusly problematic.

All sorted thanks to help from JJ and bit of the Net and some experimentation. I think JJ was right about it being a ground loop issue? I solved it but earthing the outer sheild of the RCA lead to the head unit. I used about 5" of wire and wound it round the lead and back onto the deck. I am thinking the head unit may have a problem with its RCA jacks. When I get the new head unit in a few weeks I should know for sure.
I am now wondering if that was the problem with my old amp and not some internal fault. Amp is probably gone by now as I left it with the repairman over a week ago after I took it back a fourth time.
