That info from Rockford's website is interesting. The Flex41 amp has an Ethernet and a USB port. They explain the purpose of the USB port at the link Eggman posted.
Looking at this picture I found of a Flex41 amp, the Ethernet port does appear to be for a remote bass control. But I would call their tech support and verify that before buying a control.
