You would need to know the weakest point in the power distribution and you'd need to know the peak and nominal current draw in Amperes. If it's a device that uses a surge of current at startup but only a fraction of that during normal operation, you would need a "slow-blow" fuse. If the current draw is consistent you would need a conventional fuse. Still have no idea what the "head unit" is that you're trying to fuse.
