do it man, I love having 4 12''s in my WRX and I will be taking out the seats when it warms up in alaska then I will be putting another 4 in it, Ive only heard the 4 12's on around 1k each but i enjoy the hatch/wagon just make sure you haggle the guy for less so that way you can buy better struts or suspension system for the rear end, thats where i fucked up at.. lol
