if im not mistakin, the extra terminal is there so you have the option of running more subs and wiring all the subs together, without having to tap into the speaker wire, or cram the 2 wires into 1 hole... but those are SVCs, i have a pair of DVCs audiobahns and i have 8 terminals(++)(--) one side (++)(--) the other side..
