NEW Ground Zero Sound Quality Esoterica

This just in from Ground Zero who are serious as engineering about making stuff that can both break the San Andreas and drop California in the ocean as well as making now, stuff that goes so far up the HiFi route, that you CAN in fact kiss Adele, right in the chops in your car as the image can be placed right there&;..this from Car Audio Direct -UK distributors of Ground Zero car audio. (as used by Ian ‘Iceman’ Pinder and UK bass King 2012 Edd Elson on the boom side.)
