That probobly because the battery wont hold up to both the dvd,s on.They told me not to run my front dvd for more than 10 minutes without the truck running after they replaced battery under warranty.I also moved my 12 volt fridge from rap to ignition so not to over use the battery.
Changing it to rap would be easy just dont leave them on to long.
