If your car is pulling alot of power, EI multiple amps or electronics in your car, that 7.5 amp fuse will be the first thing to go.
:thinking: But the amps run off of their own power lines.
I say just replace that dinky 7.5 with whatever size fuse is on the HU then add a few amps for the clock. I have a 15 in there right now. My 7.5 kept on popping.
