jmcummings,
My stock is Radio 9,
To install rear speakers I will run wires to the back and put 4" speakers in the rear pillars.
I'm thinking to get POLK DB651 for the front and POLK DB401 for the rear. You can get all 4 speakers for about $130 shipped (buy one , second half price) from Crutchfield.
Fredvon4,
I love XM, always listening to FOX, CNN, and bunch of other talk channels. Plus they have live traffic and weather for major cities. I got Pioneer IP Bus XM reciever (permanently installed under the seat) in my PT Cruiser. But for the smart I'm using Pioneer Inno (Portable).
Thank you.
