1 6" port ain't gonna cut it. you need a minimum of about 130^2" to just cut back on port noise. With 1 6" port your port will sound like a vacuum cleaner and tuning will be s%!t. If you can't properly port it go sealed better then sounding like crap. You need like 1 12" round port. You can buy 12" round form tubes at home depot or lowes for around $10.
