[QUOTE="loopkiller, post: 5861183, member: 601690"] It all depends on many factors. There is no way to answer such a vague question. But, to ballpark it, you can assume a few things and give you a round-about answer. A 300A fuse will not blow until about 600A is passed through it for a second or so. So in theory, you could pass almost 600A for a split second. Let's assume that you have a strong 12V system. Your voltage does not drop from 15.0V even under load. (Not likely, but for argument sakes, let's just assume) 600A x 15V = 9000W x 90% (best case amp efficiency) = 8100W max power Now how likely are you looking to get a less than one second burp? How likely is it that your voltage will not drop? How likely is it that your amp efficiency is not going to drop under heavy loads? What is the possibility of the perfect storm? None. [/QUOTE]
