Does anyone have any experience or advice using cheaper rca cables?
Involuntary autocorrect in operation on mobile device. Apologies in advance.
richms: Subs still insist on using stupid unballanced RCA cables, and you are connecting something which is normally earthed into a whole lot of stuff that is usually earthed and on a different power circuit.
Not had the hum get solved with a fancier cable, but have chucked a cheap car audio isolator on the RCA cable to get rid of most hum.
richms: It was a round thing from jaycar with 2 RCA plugs, and 2 RCA sockets made to eliminate groundloops in cars. Did the job nicely on the sub too.
