Combine the spiced rum, coconut rum, amaretto, pineapple juice, orange juice, and lime juice in an ice-filled cocktail shaker. Cover and shake vigorously.
Strain into two cocktail glasses filled with ice.
Slowly pour dark rum over each drink so it floats on top.
Garnish each cocktail with a maraschino cherry and a pineapple wedge. Serve immediately.
