Yea that kinda shocked me at first. I am just basing off of what I saw on crutchfield. The Alpine has 2x 20a fuses and the MBQ uses 3x 30a fuses. I have no idea why they are rated so high like that.

I made the comment on #1 based on my experience, but kinda prematurely. I have a G3 Integra and had a 1200watt system. I am not sure of the amperage that was drawn but if reading off the fuses, it was over 120a. I saw the 200 watt and thought, small amp. I saw the 400 watt amp thought 40-60a. So I answered #1 based on that since my alternator is still running ok...shows signs of aging, but still ok. It wasnt until searching to answer #2 that I saw the fuse ratings. h:

I think the Integra alternator puts put a max of 90a. What would happen with a 130a fuse? That kind of current is never going to run through the wires...I am a bit confused on this.
