I replaced my factory stereo with an aftermarket one. I installed with the new center panel and everything. Started my 2008 Fit Sport up and radio worked just fine. Then a bit later, no radio, no dome light, no keyless entry. I searched through the forums and found out that #8 fuse was to blame. I checked it, and yes, it was blown. Went to go get another, put it in and *spark* blown. Then another *spark* and blown. Had the battery disconnected, put another in and reconnected the battery, *spark* blown. What do I do now? I really don't want to take my stereo out and rewire it.

 

You've got a pinched wire or a short somewhere. When you see a spark with a blown fuse there should be something that is touching metal. I would pull the radio first and check anything you touched.
