I decided to scrap my plans for a box for my infinity kappa perfect 12". Its a reg. cab ford f-150 lightning and basically I want as much boom as i can get in there(around 1000 watts) but still be able to have a comfortable seat position. What would yall recomend. Get a local audio shop to build a fiberglass enclosure and if so how much would it be? Should i got 2 10's, 1 12, 2 12's? . SQ is not much of and issue. I just need subs with high size to output ratio. So first i need to get a box idea that would be suffice for what im looking for.
