[QUOTE="helotaxi, post: 2707865, member: 550915"] Geneeralization that may not stand up to real world usage. Its entirely possible that your car was designed to operate forever right at its max level and that his car needs the extra speed to run at its most efficient level. Many times it is so with amps. Class A/B amps for example are at their most efficient when they are running full tilt. The typical torture test of a Class A/B amp is to run it at 1/3 power until it shuts down. The amplification factor is a product of the amp as a whole, not just the input stage. If the signal from the HU is 2V, a 1000W amp actually has a higher gain factor than a 250W amp. The position of the gain control is based on the input signal and the desired output of the amp. If the components ahead of the amp are decent and the system has a low noise floor and the amp has a good input stage, you should be able to set the gain control where ever it needs to be to get the power from the amp, whether that be at min or max. Actually, the gain would be set the same for a 250/1 and a 1000/1 to get full power from both amps from the same signal. The larger amp would actually increase the volume of any noise more. Yes you could go with a much larger amp and keeps the gains low trying to improve your s/n ratio, but good components will keep that from being needed. There is a huge difference between "all the power that the amp can give" and rated power. Most all amps can produce more than their rated power at the cost of distortion. This is why power numbers without distortion numbers are worthless. Better amps have better distortion numbers. If the amp is CEA2006 compliant, it should be able to make rated power without exceeding 1% distortion. An under-rated amp will make its power with less distortion than that. Even 1% is below the threshold of audibility. Face the music, you can't validate any of your statements with anything that resembles fact.
