2 15s hair trick

[BadInkKid5150]

I've got a 93 ford f250 extended cab truck that I would really like to wall off. I've got to soundqubed hds3.1 15s. I Would really like to be able to pull off a decent hair trick. Currently I have only one of the 15s in a truck it doesn't sound bad at all but it is way under powered. Like a 850 watt soundqubed monoblock amp on a 2 ohm sub. So would someone please give me some direction on how I can accomplish my goal? Obviously I'm going to need more power. Any recommendations on a budget amp that would power these subs? They are d2s at 1200rms. Right now I'm in the process of sound deadening the cab. Once I get that done im going to start framing with 2×4s to help minimize flex. I can build anything as long as I have a blueprint. I'm just not sure what box I should try and design slot port, 4th, maybe a 6th. My main goal is to pull off a good hair trick but still sound good while doing it. Any help would be appreciated.
