I have for sale a brand new JVC portable boombox ghetto blaster. It has an amp built in and 4 subwoofers, giving it a massive 50watt powered sound and music. They are normally retailing at £229.
This boombox is amazing and allows you to connect your USB devices or flash drive, has a built in guitar amp and mic connection and can be powered by D size batteries so no electricity needed.
The ghetto blaster is brand new and boxed, sealed packaging and comes with 12 month warranty. I bought a few for a summer event that got cancelled.
