I have a prebuilt box that came with 2 terminal cups already in place. It is a dual sub box, 2 12" woofers. Boston Accoustic G1's (200RMS @4 ohm SVC). My amp puts out 1250 RMS at 1 ohm stable. I am trying to find the best way to wire them in order to maximize efficiency of the subs. I drew a decent idea of the wiring that is currently getting the job done, however I have no clue if im running the subs at 8-ohm or 2-ohm or what. (Everything is positive to positive, negative to negative.) I don't know if this even changes the impedance, if anyone could help that would be awesome.
