We used the term in the US as well, boombox was just more common and TV English. A good deal of kids called them ghettoblasters. Less commonly used but heard from time to time was JamBox and BumpBox. IIRC GhettoBlaster seemed to be used in the early 80's more where BoomBox and the others seemed to be used in the very late 80's and 90's but my memory could be wrong. I do remember when I was younger them being almost exclusively referred to as GhettoBlasters.
