Adding 2nd HDS 12 to bow. Power Question

[Kingwood 520]

I am planning on adding a second HDS Live 12 to the bow of my boat.

I have direct power (10 Gauge wire, proper fuse, soldered) from Series 31 battery to bow HDS 12. In order add the second, I plan on splitting power with a busbar.

I direct wired the 1st unit to eliminate voltage drop and have 12.4 almost always.

Will I experience any significant drop by adding the busbar and the second unit? Is there an alternative method?

Info is appreciated.

Hook it up and see if you do, if not, then run an additional line. I think you'll be ok.
