I've used iPhone4 speakers until now and there is no comparison. Far better bass and rumble with the 567 ULT sound file. I used a dab of Goo contact cement to secure the custom-designed speaker. I also used copper beading tape to make a "trace" on the component tray for the common (blue wire) connections. Makes for a neater job.

As others have said, nice install and great idea. How do you insulate that common "rail" from the chassis? Also, does shortening the wires that much cause issues when getting to the drivetrain for maint. later on? I've been leaving some extra wire to in theory be able to take the tape off and move all the electronics out of the way a bit to allow taking the chassis weight off for access. Obviously it doesn't look as clean with the extra wire.

For this install, the copper foil tape only runs along the plastic component tray, and does not contact the chassis. I am also careful about covering any wire-to-wire connections with shrink tubing, to prevent accidental shorts. The copper tape sold by Cir-Kit Concepts for dollhouse wiring is insulated on both sides, and looks like it's suitable for metal chassis use, though I have not tried it. See the copper foil tape thread for a link.
