Twice the speaker twice the sound?

If I have a speaker playing music and I add an identical one next to it does it double the volume? Also if I have a room with light bulbs and I add more light bulbs sure there will be more lit area but will the brightness intensify? Is the Suns surface really bright or is it just so much kinda bright light that it all come together because it's so big and looks really bright?

    I'm not sure about sound, but light definitely doesn't work that way. If you have a 60watt lightbulb next to a 40watt lightbulb, you won't have 100Watts worth of light - Only 60(becuase this is the brighter) - Illumination isn't additive. So the sun isn't bright just because it's big... it's bright because it's extremely hot
