I'm working on my Scion stereo installation and I noticed a muffin fan mounted above the stock radio. I'm pretty sure its orignal equipment. Its wired into the main harness so I'm not sure exactly where it goes. Since the stock radio uses the external amp, I wouldn't think it would need a fan. Maybe the Scion radio will actually power the thing. Has anyone ever dug into this before?
