Adams said: "We've had a few good results and performances recently and confidence is high after the win against Watford last weekend.
"The players all comment about how much of a difference it makes to have the fans behind you and we're lucky that our supporters have been absolutely fantastic for us.
"If we can get as many fans as we possibly can into the ground against Cardiff this Saturday it will be great.
"It's a fantastic feeling to hear a packed stadium behind you - especially in important games like this."
