Polarity question

Question - My amp has red / black retminals. speakers are labeled +- and speaker cables are red / white color coded. Cna some one help me to make sure I get the commections right? Thanks Andy.
Red is positive and matches with the plus symbol. Negative or a - sign is matched with any other color.
I have never had the red stand for anything other than "hot" or plus (+) on any component. The only time you would not match up the plus (+) with the plus and the minus (-) with the minus is if another component in the system is phase inverting. Usually this would be the preamp. Your owners manual would alert you to this so you could correct at the speakers by reversing the procedure I have suggested.
