Benson, nope. It’s also cheaper cause you get cost. I paid $275 for that one sub with the box included which was a fairly decent price.
Are you going to put it in a ported box? Cause they will both need to be in a ported box in order to be fair, otherwise, my sub would have definitely beat yours in terms of bass. 
And you of all people should know that a lot of this has to do with the deck, the amount of pre-outs voltage that it can put out. The type of cables used. Whether or not you have a cap (might help a little maybe, im a newb), and the last thing is the amp. It’s not how big your sub is, it’s how you use it.
EDIT: I guess you are talking about Sub vs Sub, not system vs System.
Just to let everyone out there know though, it’s not just about how great the sub is. You gotta make sure you have a good amp and a decent deck to back it up.
