Ok, dumb question but don't want to hurt the sub or amp. I have an orion 2500d, and I have one sub. There are 4 speaker terminals on the amp. Do you just hook up to one side, or do you go + on one side, and then - on the other side as a bridge type hook up? hope this make sense. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
