Speakers are only as good as the amp that pushes em. And vice versa.
BS! Speakers are the most important part of a stereo system. Bad speakers make a top end system sound like sh*t. while quality speakers will make a substandard system sound better. Amps are nice, but not really necessary any more (unless you're going for "wake up the neighbors" loud). Most decent head units output 15-30 watts RMS with 50-75 watts of peak performance. More than enough for the casual listener.
What's so great about Eclipse? From the information I could find theere's nothing special about their specs. I'm not trying to dis your choice, just curious why you chose it.
