I have a 2007 Honda Civic and have an aftermarket radio and I changed my battery out and now my radio will not power on I have checked all my fuses

 

Pull the radio out of the dash and connect some temporary wires between the car battery and the 12v power wire, 12v memory wire and the ground wire. Does the radio come on now ? If not, check the fuses at the back of the radio... if there are none, you may have damaged the radio during the battery change.

Funny thread title by the way... SOS means "Save Our Ship". Heheh

 

Okay will try that out I thought it could be from the radio sSecurity feature
