I should point out that the target audience for the front panel text are visitors to car audio showrooms

In that case you need to steer well clear of the word 'Jukebox'. Joe Punter's experience of ICEs will generally be limited to head unit and changer in the boot. You say 'jukebox' and they'll think you mean 'changer', then not look any further - who wants to buy hi-fi from a company who doesn't even know the correct terminology?

If you want the unit to advertise itself without being turned on, then you need to use terminology which won't be confused with existing products.

How's about something like:
"[empeg logo] Digital Audio Decoder"
"[empeg logo] Digital Audio Storage System"
"[empeg logo] Digital Audio Management System"
"[empeg logo] Digital Audio Library"
"Digital Audio Storage [empeg logo] Decoder"

Where "Digital Audio" and "[empeg logo]" are optional/moveable.

Just my 2p, but I REALLY REALLY think you should avoid the word 'jukebox'.
