As much as we have talked about separate, super capacitors, and how much they might (or might not) help, we haven't talked much about the capacitance of the amplifiers themselves. I would have to assume that expensive, high end amplifiers would have more capacitance than budget amps. I've tried to find capacitance ratings for amplifiers, but it seems like this info is a pretty guarded secret. Anybody know where to find these numbers, for comparison ? ....to each other, but also to separate super capacitor banks.

Edit; Also, is capacitance the only potential bottleneck in modern car audio amplifiers ? What parts of a top end amplifier are beefed up to reduce these bottlenecks ?

1) Only if space allows and usage dictates.
2) Service manual, board schematics.
3) No, everything is a potential bottleneck, but mostly power supply, capacitance, and transistors. Usually beefed up amps would use parts capable of producing more power than required.

What it is the amplifier a bottle neck of?
And what is the effect of such a bottle neck?

If one is playing a 1000 Hz tone, then does it only play it for a while and then start clipping?
Or is there some way to know whether the power flowing into it is not keeping up?

If the amplifier is rated at 100W RMS (with some % of THD+N) then doesn't that sort off tell us that should not worry about the amplifier running out of puff at the rated power?

And then if we want to run at a higher power, then we just need buy amplifiers with a higher rated power.

It seems like it is not a real issue on anything but Subs and maybe MB?
But one could run a pair of M443s for each MB and that gives a decent sized amplifier for them, or some big Class-D monoblocks... then we only have subs to contend with... and "we" may only be the SPL or SQL crowd.

This is related but different. Wouldn't it be nice if there was an international standard for rating amps and manufacturers followed it? Power in RMS, THD, SN ratio, dynamic headroom capacity etc. And tested and published for 2,4, and 8 ohm loads. Then you would know what you are getting.

Thrown in damping factor, as the complex impedence of the speaker, and it gets muddy.
How it drives a resistive load, tell a lot, but the complex load can be complicated, or even complex.
