you need the enclosure volume and what frequency to tune to before anyone can give you port lengths

i looked on pspinc.com and they said each port 5in is that enough??

You're gonna have horrible port noise and weak output with 3" ports for 2 decent twelves. Should be at least a 4in port for them and flared on both ends. You'd be better off doing a slot port and rounding over inside and outside edges versus pvc with no flares.
