Okay. this has been posted and asked more than a million times before, but I was always confused by the answers given before. I'm somewhat simple minded. anyway...

What dirrection SHOULD the SUB be facing for best bump/sound? should the speaker face the back seat? should it face the trunk opening?

and how about the straight up (trunk floor mounting)? Are there any certain angles that should be avoided for some reason?

I'm trying to come up with a new design scheme for my system but i need these things answered, first.
check out what i've got now:
click here, then on "the car" on the left

The amp direction doesn't matter.

From what whiterabbit and ludlam have said, bump = facing trunk lid. But SQ = facing you.

not necessarily, its all car dependant in the long run, but check out this article here

Thanks...but i get confused when it talks about the back of the trunk, aiming to the front....i don't know what the back of the trunk is!!! depending on where you are in the car, or out of the car, the back of the trunk is two different places.......to me anyway. so i need at the opening, or at the seatback....which is which?????

best way to find out:

assuming your box will not be movable, you take a crappy temp box and put a woofer in it.

throw it in yrou trunk with yrou car setup how it will be for daily driving (seats up/down, paneling where it will be, deadener where it will be, etc etc etc)

try all teh positions. hell, even trow it on blocks to downfire if you want. try facing to the side in teh back of the trunk, loading agasint the wheel well right agasint the seat. up, down, sideways, crooked, any which wya you want, each time close up the trunk and jump in teh car and close all teh doors, listen to a bit of yoru favorite music.

once you find what sounds best or gets loudest for you, youve chosen a site to fire yoru woofers! then you cna design yoru box around which way you fire yoru woofers.




when i was designing my box for the first time ever, i asked the same question as you. which way should i fire? which will give me theoretically the response im looking for? i got the same answer every time "darn man, what yoru trying to do has NEVER been done before, so i have no idea."

eventually i learned i cna simulate performance this way, so i took an entry level eclipse 10 in a prefab box and thrw it in my car, started toying with positions. found out that down firing and backfiring at an upwards angle sounded best in my car using my positioning.

considering box design, i realized soon that firing back wouldnt be a sinmple desin at all, nor would it really let me build the wya i wanted/needed to.

so in my car my woofers fire down into a board, plane loading agasint it. and it sounds ****ign amazing.

I highly reccommend the test method as better than even theory, because even theory cna take a back saet to real world performance

all this help is great, i really appreciate it...but now for some more stupid questions...

what is "down firing"???

and i still wanna know what the back of the trunk is...and which way would be facing forword

 
Rep Power: 338

facing forward = facing the windshield

facing back = facing the liscence plate

back of the trunk: where the licence plate is

front of the trunk: where your strut towers are, also teh back seats

down firing: firing down as in, firing into the floor, as opposed to back, up, forward, at an angle, or to the side

So once you decide on a position what is a good way to mount the sub box so that it isn't movable. So that somebody couldn't come walk off with it if they break into your trunk?

If someone wants it, they will get it.

but to make it a lil harder, make them work for it, you can get angle brackets and bolt them to your trunk, and use bolts with different tops, one hex, one phillps, etc

ha ha, good tip with the different screw heads....thats funny.

Or you could build a box like whiterabbit has.....the fills the entire trunk and backseat.....an enclosure so massive you have to take it apart to get it out. I think he has around 20 cubic feet of airspace. I dont think anyone will be stealing that anytime soon

 
Rep Power: 338

dont worry about theft proofing your car. that should be the least concern you have. not to protect the stuff they will steal, but to protect yrou car!

the easier it is to steal, the less damage they do to the rest of yrou car ripping everything out. you make it hard to take out, and you wont believe the mess they will make of yrou car.

I'll give five dollars to anyone who could steal whiterabbit's box. That thing is a gargantuan ****.

mine wont come out of the trunk either. had to build it while it was in the trunk. but why would you want to steal wr's box? just steal the subs. I bet i could jack his speakers in a few minutes

 
Rep Power: 329

Arent his subs downfiring? If they are, dont you have to move the box to get at them? I donno, i'm just guessing.....blah. I'm tired and going to sleep.

 
Rep Power: 338

you cant move the box, a majority of the outer skin of the box is the frame of the car, actually....

can you post pics of your setup WR? or are they already here somewhere?

I searched a little, but I'm kinda lazy

gimme 2-3 weeks, when i have the plexi cut. THEN ill have something really neat to show off. till then, its just plans within plans within plans

For those of you that haven't seen it - picture a huge black box taking up the ENTIRE trunk and the seating part of the back seat. That's all I've seen. When I say it's a gargantuan ****, I'm not kidding.
