Check this out i built a box for 4 12s in a ford yesterday and it sounds funny.

the box is ported/tuned to 40 htz. the 12s face to the rear of the trunk and the ports are facing up thru the rear deck.

now when the trunk is open it sounds very good hits very hard but when you close the trunk you almost lose all

the sound. what have i done wrong. I feel like i am missing something easy.

Thanks.

Sounds like a cancelling issue to me. Try positioning the box in different ways if possible to see if that makes a difference.

sounds like cancellations also...how did you know that alignment would work well with that vehicle anyways before building the box...should have stuck with keeping the subs and ports on the same plane.

but you can try moving the box in different positions

put the subs at the back of the trunk, face the subs toward the front of the car and that should sound alot better, but like everyone else said you are having serious cancelation issues. you're getting more bass output with the trunk open because the front wave is allowed to escape outside the car and not cancel out the rear wave coming from the ports. move the box and you'll be amazed how much better it will sound.
