I was givin two speakers about 2 ft tall. They're for hooking up to an amplifier but I have a question about the wiring as I'm not speaker tech savy. On the back of each speaker there's 4 ports. 2 black and two red. The two blacks are hooked up with a wire and the two reds are hooked up with a wire. They're banana plugs but my question is since the the four are wired into 2 seperate colors do I just need two banana plugs into each speaker? I know this is worded horribly but i can't post pictures from my phone right now..
