I do design sub enclosures for a living and I give free specs on basic setups, so you are in luck. As a starting point I'll start by saying that fitting them under the seat may not work that well. Each sub will need about .75 cu.ft. sealed and probably double or triple that for a good ported box. I can get more specific If you e-mail me (email@example.com) the specs on those subs. Specifically I will need the Theile Small parameters ( these numbers-VAS, QES, QMS, FS, etc,) and then I can give you a better idea of where they will fit. If they do go under the seat they will probably not produce really low bass because smaller boxes generally produce higher bass tones. This decision should be based on what you listen too and what you expect them to sound like. They most likely will be more thump than boom and some people like that, so figure that out as well and let me know. Also my father has the same truck and there is a lot of room under the back seat. You can also gain some extra space by using fiberglass to conform the enclosure to the contour of the truck.

The two seperate wire terminals on the sub are for dual voice coils which means. If You hook up the first terminal to the second terminal then run speaker wire from the second terminal to the amp.It should then increase the subs frequency response and sound better which also means it will be able to handle more bass. As to just having one voice coil hooked up. The two terminals is pretty much the bridge for the sub.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

+ output from amp to + input of 4 ohm to + input of 8 ohm AND - output from amp to - input of 4 ohm to - input of 8 ohm is a parallel circuit = 2.66 ohm impedance load for amp
+ output from amp to + on 4 ohm - on 4 ohm to + on 8 ohm - on 8 ohm to - of power amp is a series circuit = 12 ohm impedance load for amp. Clear as mud??
