connectors for subwoofer cable

[nandac]

i have a couple of pinnacle baby subwoofers for which i would like to replace the default cables which came with them.

my local profx guy has chord crimson subwoofer cable. but can only use mx connectors on them.

are these connectors which cost Rs 50 good?

what other options do we have for connectors in india or through ebay etc?

the cables i got with the pinnacle subwoofers apparently are "Includes 10' High Quality Gold Plated Interconnect Cable". how difficult is it to take the gold plated connectors from the pinnacle cables and put them on the chord cables? is that worth it?

appreciate any insights.

is the subwoofer plug the same as a analog interconnect plug (the one between cd player and amp)?
