Went to start my honda, and everything light up fine on the dash but my kenwood head unit didnt turn on. Battery is juiced up fine though, would this problem be a blown fuse? Maybe the wiring harness...if any one knows post please im not that experienced with car audio!

 

Check the fuses. If they are okay, it could be a fuse wired to the headunit.

Did you install it? How long has it been in? If you didn't install it, did the person who did cut up the old wiring to save $7? What model is it? I have a Kenwood and it will sometimes not start, so I have to reset it. Have you tried that?
