Can AC wires on rectifier to be reversed and still work?

Hi All,
Sorry for the noob question but I am trying to install a bridge rectifier on my Quad 405 power amp. Does the two fused wires coming off the transformer for the AC to the rectifier have a preference as to which terminal they go onto or it doesn't matter because it is alternating current. I know that there is a positive and negative terminal but the two AC terminals are a mystery. This is my first time installing a rectifier so I want to be sure I don't hook this up wrong. Thanks in advance for any response.
