fuse question

[mrjoeyjiffy 10+ year member]

So I've gotten all of the components for my system except for the subs, and my buddy has two kicker l5's with some "nitro" amp or something and I wanted to see what the hifonics brutus bxi2006d I bought could do. So we hook it up, set the gains etc, and the difference was huge...for about 30 seconds, til my amp shut off and I realized the fuse under his hood blew(keep in mind this was my first time so much as hooking up ANY piece of car audio equipment, i've simply been doing a bunch of research the past few months).

Anyways, his amp was only a 30a and blew in just about 30 seconds, judging from what i've heard about all these amps a fairly big amplifier would draw, is 30 amps a really small fuse? Im mainly asking because with everything hooked up in my suv im hoping to be drawing 1500 or so watts(dont know for sure because hifonics are a bit overrated apparently) and that seems like i would need a much larger fuse. Can anyone give me some input here?

my sig has all my equipment if that helps.

If his amp manual recommends a 30A fuse, than that is the MAXIMUM size fuse the manufacturer deems safe before the amp "blows".

It doesn't matter what YOU think or feel, it's what the manufacturer deems appropriate per their testing of their own equipment.
