So if I put a driver like this in a 150 litre box, what problems do I
encounter?

How's your back? Do you really want to carry something the size of a fridge to gigs? Do you have a house with a lot of space and a big car?
Other guitarists will laugh at you. Some insensitive people will wonder whether you are compensating for the size of your penis.

Why are guitar speakers put into small boxes? To control the
amount of bass they produce?

Because they don't need to produce large amounts of low bass.

How will my 150 litre box sound?

Just guessing, but your cabinet will probably sound boomy and boxy.

It's already nearly finished, what kind of
results are you predicting I will get? If it is too bassy I will remove the
bass reflex holes and then I will have a 150 litre sealed cab. How do you
think it will work that way?

Boom boom boom boom. Fart.

From my experience, normal guitar cabs sound like they lack in bass
response. They are tight, and clear, I want something with a bit more bass.
What should I go for?

You may be confusing excess treble with lack of bass. I think the driver you have will give you the nice, smooth, rounded sound I think you're after. Build a sealed cab, as opened back cabs tend to be brighter (i.e. less bass). What did you think of the sound clip? There was plenty of bass there, wasn't there? And there's always the bass knob on your amp.
