my brake lights and rear speakers wont work. used to be able to light a bulb with the brake light wires under the dash(to check for current running thorugh) but u can ne more and the brake lights wont turn on. also rear speakers arent working?

 

Check your fuses. Did the car come stock with rear speakers?? double check the wiring

 

installed speakers and they worked. im putting a new brake switch for my cruise control swap and now they stopped working. i dont see any fuses related to them
