Hi, I've searched but with no luck. As the title says my radio (aftermarket) and my speedometer cut off when I apply the brakes. Today was the second time it happened in 3 weeks. Usually, if i restart the car the symptoms disappear. It might be wiring, but not sure. Any help is appreciated.

 

Bump, I'll like to know.

 

I have my battery mounted in the trunk... I have a circuit breaker back there as my prtection device... When ever I corner pretty hard my sneakers usually hit the breakers button disabling the battery... The only thing telling my that my breaker went off is when I'm pressing the brake , all because my speedo goes crazy and my radio goes off an on... I'd say u make sure ur battery connections are good and tight... Make sure the cables don't have an open in them.. Or simply see how much voltage ur battery is putting out

 

yea happen to me and it was my battery cables were loose
