Use the subwoofer 1 out that is right under your HDMI #5 and connect it to the SVS to either the left or right input, it really doesn't make any difference. Then follow the instructions on how to set up your subwoofer in the manual. ( I hope SVS has a Portuguese section). How fluent is your Espanol? I'm sure they have the instructions in Spanish.
