What is the line voltage from an electric guitar to the amplifier? How many amps?

I'm thinking about installing a guitar plug/jack on a portable light box (12V, 60W DC). Just looking at them, I think guitar plugs should have no problem handling the load but I thought I'd ask before going down this path. The original wiring frayed at the stress relief bushing on the side of the light box because the wire gets flexed 90 degrees in the storage case. I figure a guitar plug/jack would solve the problem. There is space inside the light to accommodate the jack.

are you talking about a 1/4 in mono plug? 12v 60 watts will be fine. Many lower quality passive speakers use 1/4 in for the amp input. why not use something designed for power though? Trolling motor plugs are popular, as are Anderson connectors for DC. also... 1/4 in will be exposed when it is powered and unpluged. home outlets and things designed for power are female or protected from arcing ( like a barrel connector on a laptop) for a reason.

Thanks for the suggestions. The other end of the cord is a male cigarette lighter adapter so no worries about live voltage on the exposed plug, I'd make sure to plug in the battery last. Trolling motor plugs look good but may be too big; I'll have to go see one in person. They would be better for keeping dirt out of the light box if they fit. I couldn't find a recessed or flush mount Anderson type socket.

I went with the 1/4" phono plug and all is well. I was once again reminded that my understanding of soldering theory is much further advanced than my skill level in actual soldering but so far no fire and the fan and lights come on so I'm happy.

As a result of going down to Guitar Center to purchase the plug/socket at new guitar is coming to live with us. More on that in the guitar thread.
