Last week I took my ride to the track and my stock radio along with the clock and side mirrors went out. I replaced the fuse which is a ten and it keeps on blowing out, I tried a 15 and 20 and still keeps on blowing out. I have checked all other fuses and they're working fine and it seems that this fuse is now getting more power, what should I do? I was thinking of checking with a multimeter to check how much power is going through that fuse. Is it time to take it in?

 

Sounds to me like you have a power wire somewhere along the way grounding out. Pull apart the dash and check all your wiring.
