So I just got a 93 Cutlass Supreme. I took the old speakers out of the back of the thing to replace them with my good speakers. However, for some reason each of the two back speakers has 2 sets of red/black wires going into it. So, when i tried to put them into my new speakers (with only one set of +/-) it didn't work. I tried everything, does anyone know if you need a converter or something thanks
