Toyota Sienna XL30 adapters that perfectly fill the space between the door panel and the metal door sheet, so just like the original, the sound only goes out to us, not back out and "bounces" around the door casing. The adapters have a roof to prevent drips on the speaker and are designed to fit the door mounts. They're glued together in two pieces because they didn't fit on my printer. I used the original connectors, but you have separate them from the OEM speakers and solder them to new ones.
