[QUOTE="helotaxi, post: 4959872, member: 550915"] Where in the heck did you get that? Only reason that I ask is that it's completely false. Again, what? Again, totally wrong. You really don't have a clue. The screen-name is a joke, right? Nothing above is physics as realized on this planet. Your fault. There are major differences between different amplifier designs when it comes to efficiency. Amplifier topology plays the biggest difference but the design of the power supply plays a big role as well. For example the JL Slash amps are Class D amps but are some of the least efficient examples (more than 10% less efficient than an "average" Class D amp of the same power) because of their regulated power supplies. Along the same lines, the PG Xenon amps made the same power into any load between 1 and 4 ohms but were significantly less efficient into a lower impedance. [/QUOTE]
