My brother in law has had one for sale for some time now. Don't remember what he was asking, but I do believe it is the amplified version. After you pay +/- $100 for the radio flash, the sound blows away the base sound system. He didn't like it because it completely blocks your view out the rear. I've often considered trying it out. Sorry I couldn't answer the question on the non-amplified, my only experience has been with the amplified sound bar.
