Just 2. For this, lets assume spades.(#1) The speaker end has 2 spades the amp end has one spade naturally Xs 4 for L&R Xs two speakers. Most all amps have provisions for just the one set so it is easier to hook up.(#2) Is seprate hunks with spades in equal #s on each end.It is what frenquently bends the spades,trying to attach 2 spades on one binding posts.Many bend eaisly.Some Mfgs use a different wire within the "shotgun"(# 1)for the lower speaker post. The other method(#2) is single biwire. Clear as mud?
