ok before I buy the woofer.. I just want to make sure I can hook it up properly. now this is what the back of my reciver looks like for subwoofer wise now I read the instructions for the dayton sub and it says does this mean I will be hooking up some red RCA wire from my sub to the subwoofer out on my reciver? Also it say to use the red.. now is there a reason for this? I know red is right and in the picture in the instructions it shows the setup with the sub on the right. I will be putting the sub on the left for my setup tho. So do I use white or just do as it says and use red no matter what? OR do I not hook it up like that at all? thanks.
