Default anyone know the power eff. on this amp?

SS RUB 2500

i talked to tech support and they said they dont rate them. (he was a load of help with my other questions also)

and i have looked for a few mins on the web to see if anyone had a clue, and i couldnt find anything reliable.

im trying to figure out all my power voltage/amps factors and needs for this amp.

i have heard it was all the way up to 86% @ 1ohm
i have heard it was as much as 80% @ 4ohms

What does it matter The reason they don't do it is eff. varies to much from application to application that its almost impossible.

No one goes on eff. ratings. Its just understood that class a or a/b are less eff. then class d. Which is usually around 65-75%.


Only thing you should worry about is if the amp does rated power....

Its funny you ask this, but in another thread you want to run it at .5 ohm.

Umm, okay, I wanted to know because I wanted to know the current draw of this amp. I wanted to make sure I'm feeding it enough power to prevent clipping.

I think you are a bit confused as to what your wanting.

Input signal is what clips the amp.

i was told low voltage can cause clipping. but i still want to know the power eff. so i know the current draw.

Relax.. it was a simple question.

I think most Class D amps claim around 86% efficiency at 4 ohms for those that do actually list a spec. It's only downhill from there and where most people run them I'd agree with the 65-75%

Suffice it to say if you can supply it with the amperage the fusing is rated at, you will be fine.

Low voltage does not cause clipping. Over-driving the amplification circuit causes clipping. {asking it to do more than it can with the given input signal & Or with less than it needs}
Low voltage can cause power supply transistors to blow up because they overheat due to the excessive amperage needed to make up for the lack of voltage.

Low input voltage causes clipping. [RCA voltage]

In short, if you are worried about clipping, get a line driver. Hifonics MX-3 is one of the most amazing audio pieces, ive ever used.
