How can I add the word Subscribe: before RSS Feed Icons and Link Text?

I like having the RSS Feed Box in the header area. During my beta testing however, someone commented that they didn't understand what they were for -- a valid comment.

Is there a way to add "Subscribe: " or "Subscribe To: " to the RSS box so it prefaces the selected icons?

I tinkered a bit but couldn't come up with anything that worked.

Thanks in advance.
