Hey I was wondering if I was giving my speakers the most power I could give them. See I have the Sundown SAE-1200D installed and I have a Autotek Mean Machine 100.4 also installed. The sundown has a 150 amp rating and the autotek has a 70 amp rating. My power wire is 0 GA but I still have my old 100amp ANL fuse on the line from when I had 4 ga power wire...the ANL fuse hasnt blown for the 2 weeks Ive been playing my system and I usually have it close to or it not at full tilt. Shouldnt those two amps have blown that 100Amp ANL fuse if it was playing rated RMS???? The autotek is 100 watts x 4 and you all know what the 1200 does....

Kinda.

My aq2200d only drew a max of 94 amps because of high rise and my sundown maxed around 60A... so for a 290A total fuse rating, i could have gotten away with 150A easily.

Not necessarily. Fuses have to have constant draw exceeding the rating for several seconds, not instantaneously. And since music is dynamic, it could draw 150 amp for 1/2 second, then 20 amps the next. So it's not over the rating long enough.

I had an 80 amp fuse on a 1000 watt sub amp and two interior speaker amps with a ombined 400 watt rating and it never blew in the years I had it on there.
