[QUOTE="JonJT, post: 1061990, member: 560788"] While the formula is correct, your also assuming that your amps are !00% efficient, which is not the case. Class D amps are very efficient, in the 90% range IIRC, but most other types of amps are not, and I'm willing to bet that most everyone has a non class D amp in their car. Also, efficiency decreases as temp goes up. Your going to draw more amps than your going to calculate using that forumla. [/QUOTE]
