1st Gen Standard Cab Sub??

Im pretty new to the Toyo Taco scene... Havent had mine very long, but I LOVE it!! of course, being a standard cab the only complaint is space... its not that the truck isnt comfy, cause it is... its finding a good sub/enclosure/amp combo for it... a lot of people opt for some sort of behind the seat setup, but my truck fits me JUST right with the seat all the way back and it leaned the rest of the way... the only true option I can see would be to mount the sub in a custom enclosure between the seats... I dont have a console there, so its wasted space as far as Im concerned... I think a downfiring 10" would work wonderful there... ported even better... but I dont even know where to start... does anyone here have a standard cab with a "system" in it that could give me any pointers? My initial setup was a Kicker L5 or L7 10"... but anyone with any info on a better idea PLEASE help me out... and for that matter... anybody with ANY info help me out! Im kinda stuck!
