Hi guys & gals, my 1st post, so go easy on me. I've bought a cheap pair of outside speakers for my garden. Unfortunately they do not have connectors on the ends where they connect to the appliance, just bare wire. I have a surround sound system that I would like to connect these speakers to & have 2 ports on the back of the subwoofer, marked up as " AUX INPUT". If I buy connectors, can I put them in these ports?
