i'm gona fit some door poppers soon and im not sure where the nearest constant 12v feed is near to the doors, or whether any of the wires in the door are a 12v feed, anyone got any ideas?

cheers

Not 100% sure what you are on about but the nearest I know of is the 12V feed for the lighter socket, I wouldnt get a feed off something like the windows as that will cause problems when trying to use them at the same time like blowing fuses.

^that basically,
i already know the window motor supply won't work, that's not a constant feed, only comes on when you turn the key once

Right, well it depends how much current they need. You might be best creating a dedicated 12v line from the battery with appropriately sized fuse.

yeah that's easy enough for the drivers side door but a pain for the passenger side cos i have to route a wire either behind the dash or under the carpet somewhere then through the door
