I have a removable batwing coming my way, as well as a marine head unit that I'll be using to power the speakers for now.

What's the easiet way to wire power to the head unit? Can I use the power that's wired to my aux lights which I've removed? Or should I just run new wiring from the battery?

I'll also have to put some sort of waterproof connectors in to connect/disconnect but that will be easy enough to figure out.

Thanks,

all CDN models have an unused power source attached to the headlight loom ( it is for the Euro position light):

or you can run a wire up from the battery ( fused)- the tank is easily removed

That's perfect, makes it a lot easier. Is this connection already fused?

 

I ran off the battery with an inline fuse. Simple route under the tank. I didn't even take mine off. Just loosened it and slid the wire through.

 

Check the power draw of the head unit you plan on using. Then make sure the circuit can handle it. On my Ultra the radio and siren are on the same 15A circuit. The headlights are on a dedicated 15A circuit. If you have non LED lights, they can draw considerable power. So, if you connect a standard HD head unit into the headlight circuit, you are probably OK if you have LED lights. But, conventional incandescent or worse Halogen can draw considerable power, so that if you crank up the volume on the head unit you could blow the fuse. BTW, fuse ratings are matched to the wiring guage, so never, never, ever increase the fuse size beyond the OEM value.

If you are putting in a head unit that is more powerful than the stock one, you will get closer, if not exceed, the capacity of the 15A circuit. Don't, even think about running a separate amplifier off that circuit. Simple math is divide the AMP peak power rating by 12, and the result is the maximum current it will draw. For example, an Amp rated for 200Watts peak would draw in excess of (200/12)=17 amps...so there goes the 15 AmP fuse if you really crank the volume with the lights on.
