Best Sub/Box option for Chevy Avalanche

[army5 10+ year member]

Looking to install some subs in my Chevy Avalanche.

So here's what I'm looking at:

1. SQ number 1 priority
   
2. Stock Electrical
   
3. Up to $200 per Sub
   
4. Listen to mostly Rock and Heavy Metal
   
5. 10's or 12's in one of the following boxes:
   Four 10's -
   02-2016 Avalanche / Cadillac EXT Pro-poly 4x10'' Subwoofer Sub B - Car
   
   
   Three 10's or 12's -
   02-2016 Chevy Avalanche or Cadillac Ext.Poly 3-12'' Sub Box - Car
   
   
6. The links provide the air space and mounting depth
   

Since this is replacing the midgate the air space is fixed. It's this reason I can go with either size speaker as I know matching the sub with the air space is critical.

I don't have an amp picked out so feel free to give suggestions on a good match based on box and sub recommendation above.

Believe it or not the last sub/amp I purchased was around '95/'96. It's three 10" Kicker Solobarics running on a RF800a.2. They are still running strong today in my other vehicle.
