6x9s in the rear deck. The doors are funny though. When you pull the door panels, you will see the front speakers (5 3/4 or some off-size like that) are mounted in some plastic brackets. This is because the window comes so close when it is down. Solution? Drill out those rivets holding it in, cut the crap out of that bracket so that is is open in the middle (formerly the speaker itself), and mount 6 1/2 speakers in them.
Try to use Toyota speaker adapter plugs so you don't need to cut wires and mess the electric system up. You can get them from Ebay or Amazon.The speakers in a 2001 Toyota Echo measure 4 inches in the dash, 6 1/2 inches in the front door, and 6 inches by 9 inches in the rear deck. The car may not have dash speakers, as they weren't a mandatory option.
