I have 2 amps, one is 220 rms max and the other is 200 rms max. The power wire i have in the car is 8 guage and the fuse up front is 40 amps. There is a small distributor block in the back which splits the power wire for the 2 amps. That wire is 10 guage (and very short) and the fuses in the distributor block are both 20 amps.
I just wanted to confirm if this sounds fine. My previous amps were less powerful but i never had any problems with the setup.
I was just wondering because i looked at the fuses in the new amps, one had a 30 amp fuse and the other had two 40 amp fuses. So i read somewhere that the total ampage for the fuse up front should equal the total of the amp fuses (which would make 70 amps, this in turn would require a lower guage power wire). However i assume the fuse up front being 40 amps is the better option to keep things safe and that the power wire should be fine for this wattage?
