Dodge Quad Cab, Not much room

I just purchased a Quad Cab Dodge and wont be putting my 15inch Solo baric in it. I need to know what 2 10's would work in this box and work well with this amp.......

Description: Kenwood 7251 amplifier produces 150 watts RMS by 2 channels — ideal for high-performance components or a pair of subwoofers. High- and low-pass crossovers adapt the amp for the job at hand by routing the appropriate frequencies to your speakers. Driving a big, power-hungry sub? Bridge this bad boy to mono operation for 460 watts of MOSFET-fueled power. Used the wired remote control to add the proper amount of bump with the selectable bass boost (0, +6, +9, or +12 dB at 90 Hz). A set of preamp outputs allow you to pass signal to a second amplifier without running another set of patch cables from your receiver. The cast-aluminum heat sink and built-in cooling fan ensure reliable operation

It goes under rear seat.

if thats a MTX ThunderForms box, then id keep the MTX in it if its actually matched up for that box.

but that encloser is 1.5  qft, sealed i believe, so use that when looking for a speaker.
