One detail--when the speakers are hooked up, they must be "in phase," or you will lose a lot of the bass sound. This is accomplished by making sure the "positive" (usually red) amp terminal is connected to the positive speaker terminal, and the "negative" (or ground or earth, usually black) amp terminal is connected to the negative speaker terminal. It probably doesn't make much difference if they're switched around on BOTH speakers, but it makes a WORLD of difference if ONE speaker is hooked up positive-to-positive and the OTHER is hooked up positive-to-negative. Good speaker cable will have the wires identifiable by color or markings so that you can accurately know which of its two wires is going where.
