Thanks for the very detailed explanation, it was extremely helpful...
Are there any specific brands of amp that are known for having tightly regulated input?
I always read about people trying to raise the voltage in their cars, why not just buy a tightly regulated amp and not have to bother with that hassle. I think getting rid of the work of trying to raise voltage would be worth the loss of the increased power output. Plus, you would always know exactly how much power you were dealing with in regards to output.
Am i thinking on the right path with this, or do i have it all confused?
