^^^^ yeah that box should fit behind your seat and the amp is a pretty good amp to power that sub, if not i would reccomend the kicker L7 8" sub, i have one in both of my daily drivers and they pound, only require a 1 cubic foot box sealed, so that is pretty small, and as for an amp, i have one running off a jbl 150 watt mono block amp and the other running off a cadence 300 watt mono block amp, total costs for the systems in both my dailys, including head unit, 4 speakers, all wires and sub box, sub, sub amp and highs amp with all wires was less than 500 for both, all the stuff is quality brand name, i got it all from ebay so you just have to know hat to look for
