My factory amp overheated the other day which caused some strange behavior. It has been about 100+ degrees lately. The cooling fans on my amp were working but the amp took way too long to cool off. When I looked closely at it I noticed the factory had mounted my amp upside down. The power plug and cooling fans were at the top. I tested it out and the fans actually blow air toward the body of the amp. There was plenty of slack on the cables so I mounted the amp with the fans at the bottom. Now the fans now pull cool air from the bottom and send it up thru the amp and hot air comes out the top. My amp fans are on less often now (they are temperature controlled) and the amp cools off much faster.
How many of you have your amp mounted upside down? ( you can use some sort of smoke to test the airflow of the fans to be sure )

I think you must have had a Friday install of that amp in the factory because your changed position is how it was supposed to be in the first place.

Yeah I know, I have seen it both ways in other cars so I know I am not the only one.

You have a lot of stuff there beside the Amp. What are they?
Thanks for the amp cooling tip BTW, I just love doing projects to keep myself busy
