I have the Delphi XM radio for my car. I've thought of getting the XM
boombox that sells for around $99. I've never heard one, though. How
do they sound?

I've heard you can also replace the speaker with certain auto speakers
and make it sound better. Does anyone know what kind and size speakers
would work in this?

How many watts/power do these thing have? What is the build quality
and reliability like?

Thanks,
Dan
