problem fusing at battery

i am in the process of installing a system in my truck that consists of 2 sets of 6.5 comps 2 15's and a 10-all clarion. i just got the amps in and found the 1500watt 11500 model has a 200 amp anl fuse on it. so with one of these amps on each of the 15" plus the other 3 amps fuses combining to over 600 amps, how do i fuse this at the battery. of any system i've installed, i've never needed anything exceeding a 300 amp anl. any suggestions o how to wire this at the battery? all the amps will be fused at the distribution block. also will i need to upgrade the factory chevy alternator? thanks

If your system is capable of drawing 600+ amps of current, then yes you will need 1 if not 2 of the biggest alternators out there. and possibly a set of good deep cycle or gel cell batteries2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
