I've had a mobile radio installed in my S-10 for years.  However, for the longest time, it was only half right.  I did the correct thing and not use my truck's accessory outlet wiring. I haven't figured out for the life of me how General Motors claims you can put 20A on a 20 gauge wire - 20A for any sustained period of time on such a small wire is a significant fire hazard.

This is the wrong way to do this.

Initially, I took the quick, easy, and cheap way out by sandwiching the radio power lead in the battery post. However, I ran into a problem a few times in the mornings where my truck wouldn't start.  I found that the positive power lead was not staying tight. I eventually removed the power lead because I like to be able to drive my truck. And besides, no power was getting to the radio, either!

Enter the correct solution.

Better Battery Bolts

The correct solution is $5 each (and two are needed). Not really expensive.

The correct solution

This works better for two ways - the first is that the new battery bolts are longer ensuring a more reliable connection between the battery and the cables.  The second is that the wires are not between the battery and the main vehicle power.  I might be over-stating that benefit, though, as I don't think the power lead lugs were causing any significant power drop.
