[QUOTE="brokeitagain, post: 3224315, member: 573484"] ok now a question of efficiency i have purchased a memphis prd 1.1000 07 model according to the math at 13.8 volts it draws a theroetical 72 amps. now if it is only ~70% efficient the current draw will be 30% higher correct? I havent figured the amperage draw at lower voltages because i am simply trying to understand this better. i am trying to figure out how many amperes my alternator needs to be able to produce. The shop that is building alternator says not to go too high due to low rpm charging issues i have with the ho alt i have. I thought i knew alot about audio stuff until i got into better equipment [/QUOTE]
