I'm 15 and I'm having a house party in my downstairs and the garden of my house, it's quite a large area and quite a good set up for a party. There will be alcohol and soft drinks and food available. I have some disco lights and the rooms all have dimmer lights? But I only have some small speakers that I don't think will be loud enough?! There will be about 40 people there. Do you think it will be okay even if the speakers aren't extremely loud?
