Amps in sequence....

Okay, let me state that I've not done this. I am just asking, mostly out of curiosity. After reading about about Vandersteen subs use the feed from an amplifier to generate the signal for the sub's internal amp, I got to wondering why or if it is possible to use weaker amps in sequence? In other words, take a weak amp's signal and feed it into another power amp to amplify the signal? I've never heard of this, so methinks it is a very bad idea, so I'm just curious why?

Thanks,
Aaron

That was the Musical Fidelity Supercharger, advertised to boost the power of your amp to the speakers while preserving the original amps sound.

Similar car stereo power boosters used to be popular years ago.

Newer Class D amps can achieve similar power levels in a small and energy efficient package that is also often quite cost effective.
