Hey I'm going to post this in 2 forums because I'm not to sure which one to put it in. I'm going to use 2 alpine amps. One will be the pdx-4.150 and the other a pdx-1.1000. How do I know what fuse amp rating I should use. I'm using 0 guage that will split to 4 guage. I'm looking for the fuse size buy the battery. I kind of heard 150 amp would be Ok. Any thoughts thanks.

 

just make a sum of your fuses in the amps.

 

add all you fuses up together, thats what you need!

 

Thanks for your help
