Those trucks are hard to get loud if you are a true basshead without a blow through or backseat removal. Unfortunately 4 - nice 8's on good power is your best choice.
I'd be willing to bet the 2 sa10v2 I had in my truck was pushing very close to 150 in the mid 40hz range. But I had 3inches of seat lift to fit the 3cube box under the rear seat. Iirc the box was 3.39ft³ before port and sub displacement. So I could fit 4 8s easy but idk if I want to go that big again. The truck is only for towing my RV and gets driven much less these days. So I'm thinking smaller.
