For heat problems, look into the A/C low pressure return line insulation mod.

I also am planning to do what you did on your Yaris! Just wanna know if you only put the b-quiet on the outer skin of the door or did you put it on the inside skin and outer skin of the door here the speaker is??

I only put it on the outside skin, because I didn't have anything to create a wall to cover the open gaps on the inside. I should probably go fix that.

Just covering the outside makes the door have a "luxury clunk" when it closes.
