[QUOTE="Raptized, post: 1251949, member: 22071"] Check the voltage range for your electronics. My radio is 9 to 14.6 volts approximate so voltage drop from ignition is no big deal and I tend to leave it on. The issue with leaving the switches on is the annoying light. A small piece of electrical tape fixed mine. Measure the drop after the switch when starting the truck. OHMS LAW Volts X watts=amps so a 40 watt radio at 13.8 volts would be 552 amps so a 5 amp circuit is what you want to get. How ever a standard radio out put is 5 watts which means it would need 10 watts input since it is 50 percent efficient by design it would need 138 amps. Use the corresponding upfitter switch. Most radios if run on low voltage will perform bad or possibly burn them up.You will have to check on your specific equipment. Also you can go the other way volts X Amps= Watts. What you may prefer would be to use an Add a Circuit and tap into a fuse in the fuse box like the occupancy sensor (Gen 1 Fuse 46 inside the cab) so that it turns on when you start the truck. It will not be on with the keys in the ignition or with the keys in the accessory position. Good luck! [/QUOTE]
