I have a 2016 Audi A3 with a kicker 4x400 on the mids/highs 4 ga power 80a fuse and a kicker 1600x1 1/0 ga power 150a fuse. I want to upgrade the big 3 or 4. Would a 150a fuse even ok going from alt to batt using 1/0 ga wire?

Thanks for any advice or responses in advance

You don't really need a fuse from the alternator to the battery but if its preferred id go with a 200 amp breaker or fuse. Preferably a breaker though.

fyi, i highly advise you do not put any kind of fuse or breaker on between the battery and alternator. But if you so decide to thats my recommendation
