building my first box for 2 hdc315's. i drive a 98 tahoe and will have the subs firing up and port to the rear. How much clearance do i need between the port and the rear hatch?

I always leave just as much or more than the port width.
But I never use ports that are less than 4 inches wide so I suggest no less than 4 inches.

whats bad with a small port say 1.5 inches?

Higher velocity which can cause ripple AKA port noise.
