Looking at the biggest factory gm alternator. I can find. Want one that came on factory truck and not aftermarket.
I have found factory 160 amp code kw1

Looks like I may need an adapter simple enough and a bigger fusible link wire

any other suggestions???? I think my amp and inverter wear out 145's a little too quick.
