i just invested in my first true home theater system having always used home theater in a box sets i havnt had much to set up for speakers. i am good with connecting components but not so good with the matching of watts and impedence situation. I have a set of 6 klipsch icons 2 floor standing two book shelves, the center and sub and a pioneer vsx-820-k receiver. Do i have to worry about setting watts befor i plug the speakers in or do the speakers just draw the watts needed also how about setting impedence? i relize i will find setup info in the manual but i was hoping someone can explain or point me to how this process actually works as i would like to understand it rather than just read a step by step setup. Thanks and be gentle im new...
