do you guys think that if i ad a second port will solve the problem?

Adding a second port without increasing length will raise your tuning... and if you add a second 1.7" port while increasing length, you still won't end up with enough port area.
You would need (4) 1.7" dia x ~24" long ports to get enough port area to prevent port noise. But you would be better off with one large port than 4 small ones.

24x24x24 with a 10" aero.

10'' aero is way too big,idont thing that i can find one....a slot ported?

the 10" aero is a joke they dont commercially sell larger than 6" and you can get those at parts express, easier to do a slot port to get tons of area. 14-20 inches of port per sqaure foot.

check here for SPL box recomendations

base your port area on these dimensions, I am not sure on your exact enclosure requirements. a few peeps run the same sub though, hopefully they will chime in.

Are you just wanting an all-out SPL box for burps, or are you actually wanting to play music with this?

Sub back-port back usually works very well in a trunk.
