Yesterday i blew the radio fuse, the 10a fuse on the driver side dash, so i replaced it with the spare on the fuse door. but the wires still arent getting power i tested them with a DMM and the ACC-red wire gets only .5volts and the yellow-batt wire gets nothing, i touched the wires to the batt to make sure the HU still worked and it powered on, but for some reason the wires in my truck are not getting power

sound like theres eaither another fuse blown, or the wires leading from the fuse box to the hu are fried.

sometimes HU's have fuses in them (on the harness)

didja check that fuse? sometimes looks like these ;

and the fuses are small-*** things like this

i know for a fact they sell those kinds of fuses (small ones) at autozone. just bring the origonal fuse when you get a new one.

look and see if any of the wires look like the wire in this picture (along any length of the yellow 12v wire or the red ACC wire)
