Hi guy and girls really need some help here .. I was sat a college today listening to music and my mate kicked the dash board its an after market radio and it just cut out .. I have been through the fuses and it had blown I swapped it over but the radio still didn't work I tryed a different head unit in the car and that didn't work .. i tryed both in another car and they worked fine so i grabbed the multi meter and checked the connections... i have 2 12v live feeds coming to it (should i ??) but it seems i have no switched 12v for some reason . it would be great if someone could help... Thanks
