When I get in and start my 58 plate GP the radio comes on but it's only the sub that is working (you hear a muffled sound only), after a mile or so all the speakers start working and it's ok from then on. I thought it might have been the cold morning but it's happening more and more even though the morning have warmed up. Today it happened every time I've got into the car. Has anyone come across this before and is there a known solution?? Not sure if it's the head unit or the wiring?? As we know the wirings not great on these cars!!
Any help much appreciated,
Cheers.
