Message: <blockquote data-quote="hispls" data-source="post: 8713539" data-attributes="member: 614752">Stock Honda alternator wouldn't make 135A if it were hit by lightning.  Real world I suspect you're lucky to see over 70A.   You'll probably solve this with a nice extra battery but due to space and weight a lot of people would opt to get into a custom high output alternator.    Good alternator will cost about double what a good AGM battery will.  But generally 2000W amp is getting into the neighborhood of you really can't do it off stock electrical.</blockquote>
