Los amo a los dos?

I know them both

'LOS' means the, 'DOS' means two (number) so i think 'LOS DOS' means 'BOTH'.

The word "los" in Spanish mean "the" in English. Thus "Los Anglees" means "The Angels."

if you meant to ask what is dia los muertos, then i could answer it by telling you that it means DAY OF THE DEAD which is a celebration in Mexico where they celebrate the death of their loved ones.
