    I Got the the 8 speaker wires, ground and constant power and the little orange data wire that runs into a axxess aswc unit for steering wheel controls wired. But were do I run the red 12v ignition wire to. Can I buy a one of those 10 amp add a curcuit taps to a run in the fuse then to the radio on the drivers side inside the dash and if I can witch one will work. Thanks in advance as this is the only thing keeping my from enjoying my tunes man.

    the ignition wire is to go to the power circuit that has power when the ignition switch is in the on position. the device your installing should indicate what sized fuse to use. I would tap off the interior fuse block at the point where you have voltage only when ignition is ON!

    So if i get a add a curcuit i could run it off one of the fuses in the interior fuse block there then to the radio someone else told me the brown wire off the ignition would work with a t-tap and a inline 5 amp fuse.
