I was going to buy 2 pairs of the Diamond Audio S500s for my 97 Ford Contour. I play on getting the Pioneer Deh-p4000ub deck. I was wondering what the rms power for the speakers were? I'm new to car audio, but I read in one of the posts that it is best to amplify component systems and not run them off the head units power. I wanted to find an amp for these but was confused because onlinecarstereo says that they are 20-150rms. That makes no sense. Do they mean that the speakers are acutually 75 watts rms? Please help, and any reccomendations for my speaker set would be appreciated. (I am going to buy a seperate amp and sub later on)
