sealed trunk vs "cabin wall"

1st sorry if this is considered a vs thread, but i was thinking since it wasn't a comparision of products it would be fine :P

but anways. i currently have 2 AQ hdc3's firing towards the trunk.

but i was also thinking about sealing them off from the trunk and firing foward into the cabin.

my friend attempted to seal by stuffing pillows into the gaps, and yielded satisfying results.

but was also wondering if i just sat them in the back seat in the cabin, would i see better numbers?

Sealing off from the trunk would be good, a wall would do better (answer also really depends on goal), but if you're just sitting the box on your backseat it will probably sound like ass...not to mention without proper ability to let the soundwaves mature, I have always seen it get louder from the trunk opposed to box on the backseat.

Tell me...does this smell like chloroform to you?

true, not to mention a much more practical solution.

my friend claimed he could feel it more in his chest, so i guess a more physical feel.

because right now it flexes everything even up to rippling the hood of my car and hurts your ears,

but i want to feel it more in your chest.

but also some big numbers.

do not waste your time just thorwing it in the backseat it wont even be worth the effort. sealing off and firing forward on the other hand can be very beneficial if the effort is put in.

could anyone explain to my why it would sound like crap if i just stuck it in the back seat?

because my friend stuck 2 kicker l7's on the backseat of his Ford F150 and it was painfully loud.

so what the difference? why does it sound so loud in a pick up truck, but in the cabin in a car it would sound bad?

the cushion from the seat would muffle the sound. wouldnt be as loud or deep sounding from my guess. although i do know one person who had a pair of big bangs that he had in the trunk rear facing and then gained 1db by putting it on his back seat facing foward. i also know some one that used pillows to try adn seal his box from the runk like you said your freind did and he lost 3 db.

There is no such thing as a trunk wall. No matter how bad you want to be able to say you have a wall you don't.

i never said anything about a trunk wall.

but what would the difference of cushion matter with the subs in the back seat and trunk be?

what i'm trying to say is i will not be putting the subs in the back seat, but i just want to understand why sealing it off from the trunk& firing it foward sounds better than just slapping them in the trunk
