Working on what sounds to go with

We have a class D Mono MTX Amp. Sounded good when we tested it
Subs we are having a hard time figuring out what 2 go with.
I had 2 12inch Alpine type S in my car they sounded good.
My son likes the 12inch Pioneer Premier.
Putting a Pioneer head unit in for him.
We are also getting the box wrapped in leather to match his seats.
Still havent figured what to go with on the door componants
He wants everything to be Pioneer but man when you get everthing to
match it can get pricey quick.

i got 2 rockford fosgate p2 12s in a box in great working condition for $150.
