I'm sorry, it's still not completely clear what you want subscribers to see. A settings page or something similar your plugin generates? Or the plugins admin panel that lists all the plugins?
For a plugin settings page, you need to identify a capability unique to only subscribers and admins, which probably does not exist. You can assign a custom capability with the add_cap() method of WP_Role class. There are also some plugins that make managing capabilities easy.
You can then use this capability in your plugin when checking with current_user_can() if a particular action is allowable. This includes adding the submenu or menu item to the admin panels.
If you are referring to the plugins admin panel, it's only possible if you assigned the activate_plugins capability to subscribers, which would be a very dangerous thing to allow. So in practical terms, this is not possible.
