I want XM, but my Cd player is "sirius ready" Can I still get Xm? And can I directly connect it to my radio?

I dont want sirius because I find their content boring. I want XM, and I want the best sound quality available because Im into loud music/car audio. Will I be able to directly connect Xm to my radio, and have it display on my JVC head unit, instead of a tuner, and just get the little antenna thing/box? IF not, can I get a plug and play? Lastly, will it use my subs? I want the best quality available,and I want it to play through my subs
