Hi and welcome to the forum.

I assume these cables are Meridian speaker cables with two connections at each end (RCA & DIN).

Are you sure the two cables are identical, check out the DIN plug pin connections at each end.

Do you have the manuals? If not you can download the from Duncan's Meridian Information site.

Please read them and then re-read them, Meridian kit is not plug and play and to be able to setup and get the best out of them you will need the manuals close at hand.

Regards,
Carl
