As promised, a short writeup on my subwoofer replacement using the 80 series Whole Hog aftermarket aluminum bracket!
Whole Hog FJ80 Toyota LandCruiser Products
Brandon from Whole Hog was pleasant to deal with, and gave me the IH8MUD discount too! I ended up having it shipped to my USA post office box in Blaine to avoid the $$ shipping across the border.
Step 1... remove factory sub and bracket. Did that about 5 years ago... lol
Step 2... find and fix those annoying small water leaks that result in water in the rear quarter panels. Guilty parties:
A) tabs that hold the small piece of trim underneath the 3rd row windows
B) tabs that hold the flat large trim along the side of the outside quarter panel (Is this even on USA 80s? Not sure)
C) moon shaped black plastic vent underneath the black vents behind the 3rd row windows. Mine was leaking like a ****
Step 3... find and buy a suitable aftermarket 8 inch sub and amp. I used these:
A) Pioneer TS-SW2002D2 8-inch Shallow-Mount Subwoofer with 600 Watts Max Power: Good reviews and inexpensive. Also meets the bracket's specs listed for being under 3 inches deep. According to Pioneer this particular sub is OK for both box mounted and open air installation, which makes it perfect for this application.

b) Boss AR1500M ARMOR 1,500-Watt Mono Mosfet Amplifier: Good reviews and VERY inexpensive.

The fitment of the Pioneer shallow mount 8 inch sub was PERFECT on the Whole Hog bracket. And the BOSS amp was quite small and fit easily in the provided blank space below.
Installed using some extra stainless m6 bolts, washers and nylocks I had... because, why not
