I had this idea and was wondering why I haven't seen anyone else do it.
use the formula power/impedance=current^2 to find how much current is running to the subs. then put a fuse between the subs and the amp. so for a 450 rms sub with an amp that can put out more than 450 rms it will keep me from blowing my sub
450/2=I^2
square root of 225=15
so if I put a 15 amp fuse between my sub and amp it will blow when I put more than 450 watts through it.
Please let me know if there is a flaw in my plan or the reason why noone does this.
