Yes you are correct and the positives go to the red dot side of the speaker. The radio grounds itself thru the dash mounting hardware and the amp does not need to be grounded as it has a ground wire thru the harness between the radio and itself. The blue wire on the amp is a positive so that speaker will ground to the body. It has to be that way or you can burn out the radio. It has a left and right fader but because they are both in the center dash spot 2"away from each other it really won't matter but if you are nuts about stuff like that you will have to check k which one is left and right as I don't remember. I believe radio rescue was bought out by another company but not sure who. I had this radio built in 2010.
