Ok...i was wiring up some stuff tonight. long story short, when i wire my headunit to the yellow battery cable on my harness i get NO power. for awhile i thought i messed up the Hu, so i checked all fuses, disconnect, and reconnected EVERYTHING. still no go. Then i connected the HU yellow batt wire directly to my batt and it's works fine, music plays system comes up everything, so im to take it that i blew a fuse, but WHICH FUSE? i checked all the fuses in the kick panel inside, they're all good, i dunno what else to check?

 

Did you check the audio fuse under the hood?
