A/B vs. D class with the same exact RMS Output?

[Bhhong 10+ year member]

So Just wondering I have an option to have a A/B amp that puts out 4000 at 1 ohm.

And a class d puts out 5K at 1 ohm. Lets just say I want both to put out 4k rms.

So the power is an issue yet my goal is to put two RD HW and get max spl.

As long as both amplifiers do the rated power the only assumed difference should be that with proper electrical the ab should sound cleaner? is this correct please give me input for those super curious

z1a is a class a/b or is the tru amp?

either way i would do class D... with that sub and that kinda power... sq would be the last thing on my mind.

that A/B is going to pull so much current...

The class d is much more efficient, probably only use 60-75 % of the current to reach the same power levels as the a/b. In your setup, sq is not part of the equation, get the class d, you will not hear a difference.

If it was a showcar I'd say get the TRU but for daily beating I would pick the DD
