RD class D amps are over 90% efficient not sure about the SAE-1000D but it should be up there.

I think the RD is 12.5volts and the SAE-1000D is 14.4volts but don't hold me to that.

they're very similar in terms of quality, the truth is you can't go wrong there

both are very similar... i mean very.. mine have done a great job... just need to keep the voltage above 13 volts to get 1800+... mine where strapped @1ohm and took it with ease... box rise was about 2.5-2.8 from 50-55...
