I'll take pics after I do some troubleshooting first. The problem appears to be the antenna wiring leading from the sirius receiver to the shark fin antenna connector. Everything else is connected correctly. However, there is also the possibility that the Sirius receiver I got came defective.

It would be nice if someone can use a digital ohm meter and disconnect their sirius antenna connector from their sirius receiver to see if it is the same value I'm measuring here from center pin to the outter rim of the connector at the antenna cable (not on the receiver's connector).
