Ahh...bare wire only eh?

I'm sure you can find some good quality 14 gauge speaker wire.

I think Monster's Navajo White is 14 gauge and low profile. Probably find it at Radio Shack.

I know I've seen 14 gauge stuff on some of the online shops, but can't remember the addresses.

Perhaps Gonk or others can point you in the right direction.

And while you could go with a thicker cable and use like Monster pin connectors, I find that the pins put a lot of stress onto the speaker's connectors. Probably not recommended.
