When adding the add a circuit to get 12v power for the amp turn on I will replace the existing fuse in port A (on the add a circuit) and what size/amp fuse should I add on for port B (to the amp which is a 400 watt amp). I read to use a 10 amp fuse max for the add a circuit. Would there be any issue with using too powerful a fuse (say 10 amp when only 7 or 3.5 amp is needed)? I also plan on using the same add a circuit process to get 12v switched power to my aftermarket sony xplod head unit. Same question here; what size/amp fuse should I add on? THX
