My wife said after the discovery "Oh that explains the lump". Considering her profession I thought she's be the first to say something about a lump :rimshot:.
This is the lump.

I did not pay for this, The Sirius was in the Baja when I got it.
So let's fix this.
Gut it, Remove all the components and let's play Tetris.

JVC controller will fit here snug with the factory foam. No wires are stretched or bent.

The tape was used to secure a cable up the controller box.

I love you two foot grabby tool!

The I ran the Sirius box here, Then used a factory screw to hold it in what seems to be a hole cut out just for it.
That red taped box is an inline fuse and filter. I mounted it there so I cloud get to it later if I ever blow a fuse.

Everything put all back together.
No wires stretched or under any tension. It's all secured and it's all above the or behind the dash.

No creaks in the dash.
No blown fuses.
I'm happy.
