best box volume

Re: that range of size you are asking about, take the usual considerations when you are deciding.  How much space do you have to work with?  How much power is available?  How much weight do you want to add to your car?  The thing is, the entire range of sizes work for that woofer or they wouldn't have been recommended.

If you have ample power availablity up to or over the speaker's thermal power handling rating, you may want to tend toward the smaller size.  If power is more on the meager end, and you don't mind the extra 100 pounds of weight, you might tend toward the larger.  And there will probably be a greater low end extension with the larger size.  With rap/SPL as your primary goal, plenty of power and the smaller sizes is the way to go, as the extended low response is generally for SQ purposes.
