connect the negative terminal of the speaker to the negative terminal of the 9v battery and the positive terminal of the speaker to the positive terminal of the 9v battery and watch your speaker. If the cone moves, it's probably good. If it doesn't move, either your battery is dead or the speaker is. Test the battery by putting the terminals on your tongue. You'll get a nice little jolt but you'll know if it's good or not. lol.
