My younger brother is 16, broke, and trying to build his first system. He got two ID10 V.3 subs for Christmas and managed to save up enough and buy an Orion 600D amp. His subs are 2 ohm DVC and the amp will make 400 watts at 2 ohms. I attached what I beleive is the correct wiring diagram, I was hoping you guys could look and make sure its the right one? The amp has 2 + and 2 - hookups but this is a mono amp, should I use all 4 terminals or just use 1 + and 1 - ???? I'm probably making this more complicated than it is but this is my first experience with a mono amp and DVC subs. I just don't want to screw anything up!!!!
