I just have to say. Peak rated power is not the full spectrum. They rate speakers on a certain frequency. Your head unit that outputs a peak rating is rated on the loudest frequency in the spectrum. Each frequency takes a different amount of power to output. They aren't always rating things like lower frequencies, mid low, etc... It takes much much much much more power to throw a 20hz tone from the radiator than a 1KHz tone. The higher you go up should rely on acoustic horns, or much smaller diameter transducers ("tweeters"). If you use an underpowered amp on a pair of speakers that are rated for a much greater RMS and peak, they WILL distort. You NEED an amp that is rated higher than the speaker. You will actually blow the speakers much sooner if you use an underpowered System.
