how much power?

[baggenlightning]

im bagginf the front of my lightning, i have a 12 gallon tank and two 450 compressors. i made my own switch box. it has three switchs. i was wondering what size fuse i need for the power. also im not going to be able to put a bed cover on it right away, would it be ok if i put my relays in the bed or should i put them somewhere hidden?

Each compressor draws about 25 amps. The relay should be all right on the back just make sure the connections are protected against weather.
