2006 Sentra Radio Help Sirius Radio Hook Up?

[stevecrissi]

I have a 2006 Nissan Sentra 1.8S with the upgraded 300 watt Rockford Fosgate Radio. It does have the Sub woofer in the trunk and the 6 disc CD changer.

Here is my question.

How can you hook up Sirius Radio without buying all the extra expensive stuff. Does it have a hook up on back of the unit?

Does anyone make this radio for Rockford Fosgate and put Fosgates name on it?

Any help would be appreciated.

Thanks
