FIRST, LOCATE RESONANT FREQ OF THE CAR. NEXT, FIND THE FS OF THE SPEAKER (FOCUS ON THE SENSITIVITY ALSO - CLOSER TO 100 THE BETTER) COMPARE FS TO FREQ OF CAR.THE CLOSER THE BETTER. ADJUST THE PORT DEPTH FOR THE FREQ TARGET-SHORTER GETS YOU HIGHER TONES,LONGER DEEPER TONES,53-60 HTZ HITS HARDER THAN LOWER TONES. MAKE SURE LOADING WALL IS LOCATED A MULTIPLE OF THE DIA OF SPEAKER. MOVE THE BOX AROUND TO GET YOUR BEST DB READING THE LARGER THE BOX THE DEEPER THE TONE BE CARFUL NOT TO DRIVE BEYOND THE F3 POINT, THE ROLL OFF IS VERY STEEP YOU COULD LOSE YOUR WOOFER BEYOND THAT POINT
