3 12's Downfiring

[PUNKYOU007]

my buddy that bought my 3 12's wants to put them in his jeep and have them downfiring he wants to raise the box up on both sides so that the top of the box meets the top of his backseats, not sure of dimensions yet. anyway it will be 2 12's dowfiring and ported. where do you suggest we put the port? will the subs downfiring make a difference?

Personally my experience with the downfire is they sound about the same. I had 2 jl 12s sealed in the back of my truck and i got a downfire under the seat box to save space and when i first put it in it was a little different but the box was too close to the ground and the sound was a bit muffled. I put a small spacer on each side to raise the box about 1/4 inch and it sounds the same as my old box.

I am in the same boat as you. I am thinking about going with a downfire but dont know how high off the ground to go or how to port it

your port is the space between the box and the floor and the rear door.

i havent ever made one or would i but i thought some guys were going subs and port firing down and the floor and back hatch make the port longer allowing the tuning to be droped but i could be wrong

I have also seen some like that.

yuup we both have and we have both smelt what it did to the subs lol

I think that would be user gain error not the box.

to the op... why do you want to do a downfire?

space issues?

well this setup is for my friends jeep cherokee. he wants to be able to put stuff on top of his box, since most likely he will loose alot of space in his truck. i told him that it didnt sound like a great idea because what ever he puts on top of his box is gonna get beat to hell plus his likely to hear it bouncing around on the box. but he is my friend and you cant tell him anything. he always asks me for ideas and help and somehow he always ends up at the flea market looking for gear no matter what i tell him. he always finds a cheap way out of my advice. i say buy some Knuconceptz he goes and saves .10 and buys welding wire, i say dont buy Power Acoustik....he goes and buys power acoustic, i say if you wanna get loud dont wast money on $50 sonys....he buys sonys. and so on and so on and so on.

back to the box though. he wants a downfire but he doesnt really want it right down on the floor. his first idea was he was gonna put the box across the wheel humps in the back of the truck, i told him that doesnt sound safe and it will proly not sound good. my suggestion to him was if thats the way he wanted his box then build the box and add some sides to it that go like 8or so inches past the bottom edge of the box to raise it up. my only concern is do we still port the box or as thehoe92 said the space is the port? i still think he should just put the subs up and just port back but i am trying to get some ideas for everyone here first. thanks for all the help everyone.

i would probably do subs and port facing the backseat
