those cardboard boxes would be very lossy. are you sure you are only listening to the woofer or also to the box. you can make a quick and dirty box out of MDF or you can do it the old fashioned way (marineply, fiberglass, lead, etc...).
BTW car speakers like lossy boxes since most fo tehm are free air and have T/S parameters to match. So I would consider an aperiodic box for this purpose.
first build a stuff sealed box, then once you got a proper sealed box (i suspect the system Q would be high) then you can add a aperiodic port or 2 to tune the box to you liking.
