Ruchab91 Posted January 23, 2014 Report Posted January 23, 2014 Hey guys doing an instal on my car come early spring and got some questions1st What is the general % efficiency of a class A/B Amplifier.I was told it was ~30% does that seem correct? If it is.Then my 480Wrms Class A/B amp would need ~123AH correct ?480/.30 = 1600/13 - ~123AHDoes this seem correct or is the 30% efficiency low ?Thanks for help determining my Alt/Battery Needs atm.
