I just saw an old project i made called the relay amp,
It was an amp with 3 relays one at 24v on at 12 and one at 5.
Each rellay was triggered at a different voltage and made up a horrible sounding but very powerful amp.
I this worth Souping up with 200-300 relays or low rds mosfets each at different voltage,will it sound harsh or not
 
my new project

r.. audio amp.good sound.
