Is there enough room to fit a subwoofer in a 2000 GMC Sonoma regular cab?

[pills]

I am getting this truck from my cousin.I just want to see if there is enough room for a subwoofer that is not wild. but it stands out. like the subwoofer is good just for normal use. also please let me know what kind of subwoofers i should get and the size of them. also what type of amplifier.
also i want it to be a little show off. but not to much.

For a regular cab truck you are going to need the shallow mount subs. A normal sized sub is going to be to big for a regular size cab. Elemental Designs makes a great sounding shallow mount sub that is under $100. The SQ10 is the model of the sub.
