Im not saying RE knows nothing, by any means.
What Im trying to say is, there is a lot of underrating by many companies that "know what they're doing".
For example:
Alpine Type R: RMS:500 Can easily hold up to 1000+RMS
Kicker L7 - RMS:?750? Can easily hold up to 1500+RMS
Actually I doubt it...as long as you know what you are doing. I gave one 1200rms daily with no ploblems.put 1500 on a 12L7 which is rated at 750 and see what happens.. i'd be willing to bet you'd blow the shit out of them
