Default powerwheels box tunning

ok guys i have a lil problem. im trying to get my sons powerwheels to peak a lil higher. rightnow it does a 141.2 in the kick @31hz i would like to tune it a lil higher in the 39-42hz range. box is 12 1/2 x 22 1/2 x 10 3/4 only problem is port, its a 4' port with flares on both ends. im stuck at 20'' of port since its ran thew the car. if i shrink the box a lil would that be a problem with port noise? or would it hurt his scores?
HEEELPPP!!

I dont think port noise would be an issue, I use cheap caulk to attach my blocks of wood in the bottom of the box to shrink the volume when testing, if it works out good I will screw it in permanent or build the proper size box

31hz is too low for that car imo..i built the car to do some numbers on the termlab.
the box . i only have 1.24 cf net subs are inverted.. for a pair on 8s. im stuck with that only option is to shrink the box. but idk if the 4'' port would be too big for a box smaller then what i have.

I thought I saw some power wheels peak around mid 60's
Maybe I'm totally off but I thought I saw that in some thread.

My only option with this setup is shrinking the box.. port barley fit and its glued together. I don't wany to tune that high either. Leave some room for some music. He shows it off too..
