my dads got two 4 foot infinity speakers, if i got an amp would that run fine for my guitar?

I think it would but don't hold me too that I'm not sure. Wait for more replies before you try and deafen your neighbours and fry the speakers due to my advice 'cause I may be wrong.

4 feet is.......er......big.

Bigger speakers provide more low end, however, due to more cone movement, they break up more easily. The best size for guitar is 12 inches. I've played my guitar into a 15 inch speaker and that farts really hard.....but four feet....ooh, be very, VERY afraid.
