Radio to battery

[Mjcruz]

Question I have to wire a radio to the battery directly do I run the negative wire to the battery also or do I ground it to the frame? And what gauge wire should I use

why direct and how do you plan on wiring the turn on lead so it doesn't kill the battery?

That's what I thought but I second guessed myself but what gauge wire do yu think would work

16 gage is good for 10 amps which is what most cars fuse the radio for.
