I've got some schematics published in this month's Make magazine. What a
hoot! Build an amp using a cereal box as the case.
So here's one of my first questions I hope somebody can discuss.

Does the type and capacity of a battery affect an amplifier's ability to
output volume? Some of the teeny little practice amps run on a 9v battery
but can't be heard well outside. Given the other concerns being met is it
possible to get more volume using a different power source such as a battery
from a laptop computer typically 10.8v or some other battery type with
greater voltage?

I design and build my own amplifiers.
My current one is used for a disco and a guitar.
I play along to CD's in pubs and clubs.
My latest amp is 600 watts RMS.
It would need a pretty big battery LOL

It uses a differential amplifier driving some 20 amp MOSFETS
