We recently got a Ford vehicle with Sirius radio built it. And got addicted to it very fast. Now we want to get a portable setup that we can use on the boat and in the house that we can move from one place to another. Basically what I am looking for is a small boom box 40cm/16inch wide that can work on batteries or from 12 volt power source. Preferably splash proof. Size is limited by the space available on the dashboard of the boat. And the boat doesn't have any sound system. We also will need an external or internal repeater antenna for the house.

I looked at Sirius web page it's kinda confusing. Can anyone recommend a setup that will work for this application?
