When i plug in rca's to my amp with the outer shell touching, the sub doesnt work, otherwis it does? but half way it does!
When i connect the outershell, it doesnt work. Someone on yahoo questions said that it may be becuz of reversed ground or something...how do i kno if its that and how to fix this?

i am using a line level converter and could it be probably becuz the converter is not grounded properly? or that i have only connected the left,on the converter, not right becuz i just need one sub running.
Or is there sumthing wrong with the amp, then what is it? what do i do? i chekd the shields on the rca's ther fine.


PLZ HELP! :S
