Boss Audio Systems 640UI

I replaced all my stock speakers with Blaupunkt 2ways and 3ways and the EQ curves let me use the most out of those. As well I like using that feature with my subs. Great looking and sounding unit, there are no complaints. I can honestly say I've never...

I am really satisfied with the quality and look of the object.

Everything is good except you need to plug USB every time you start this radio.
