How do you run a wire through a fuse?

If you are connecting a true automotive accessory, wiring the device is relatively straightforward. Just connect and crimp the power wire from the accessory to the fuse tap, plug the fuse tap into an open slot on the fuse panel, and then secure the ground wire from the accessory to a grounding screw.

What kind of power does a pioneer radio need?

Regardless, it should be appropriately sized wiring and fuse for the application. Okay, so we are clear that the Pioneer radios (or all radios?) use the constant (yellow) 12v as their main power source. So the Alpine KPT-445/U needs 15A power, and the radio circuit has only 10A on many cars.

Is the z130bt a constant 12V source?

Much as the 12v illumination wire would signal dimming of the display. I have also seen some radios that claim that the constant 12v source is used for memory backup only, and the switched 12v carries the power to operate the radio. I have installed the z130bt in my 2005 Mercedes C230 (W203 chassis).

Where does the power come from on a radio?

If the line is not fused already, or there is no fuse in the panel I would suggest getting a cheap inline fuse-holder to splice into the wire. Always fuse hot connections as close as possible to the battery or other DC source.

Can you listen to the radio with the car off?

However, if you really want to be able to listen to it with the car off then you would have to do something like what you have done, and splice the always on 12v to both connections on the stereo. The only thing I might change is to make sure that always on connection has a fuse.

Is it possible to leave the radio on and drain the battery?

I can’t say exactly, but to directly answer the question: yes it’s entirely possible for you to leave your radio on and drain the battery. However, if you really want to be able to listen to it with the car off then you would have to do something like what you have done, and splice the always on 12v to both connections on the stereo.
