Well, so far it looks like the JBL 8-Channel Class D Amplifier is the way to go or am I missing another alternative? With this one, it doesn't appear I need any other components other than the speakers. Itll run the door speakers and the center speaker is my belief. I have a low profile subwoofer with built in amp which will go under the drivers seat, I havent picked out the door speakers yet. My goal is to be able to drive with the windows down @ 75mph and still hear the music well! Thanks in advance!
