Opinion on Sub Position?
Ok, I'm testing out several positions for my sub. Take a look at the cheezy diagram below and let me know what you think is the ideal position. I've tried a few of these positions but find it hard to discern a real big difference, what should I be noticing? It is a bird's eye view of the trunk space. The arrow indicates the direction that the sub is pointing.
The general consensus is that against the back seat is the ideal position (corner loaded), pointing back is the best position since it allows the bass to cabin gain.

Rep Power: 338 either face the woofer toward teh trunk hatch and put it as close to the hatch as you are comfortable with (the idea is to "load" the woofer 4 inches or so agaisnt the hatch)
or to have it on the side, loading agasint the trunk side (that was b)
the idea is to plane load the woofer. helps with cancelations, but it seems to me that any box you built like that you could test for yourself when you finished with it and run what sounded best.

Rep Power: 319 What is everyone's thoughts on "E", subwoofer(s) built into the spare tire well? I was thinking of putting one at the rear of the spare well, between the spare tire and the jack.

In option b, the sub would be pointing into the trunk side wall.

Rep Power: 338 loading basically means bouncing the speaker waves against an object.
in homeaudio, its called "corner loading" becasue you use the corner of the room (incidentally also gives you an 8 dB boost at 20 Hz? 9 dB?)
in a car, its just plane loading because you load off a single plane. to be honest, i would have said flat out rear facing 3-6 inches from the trunk hatch would be best peroid, untill i heard a side loaded enclosure in a firebird the other day. one of my coworkers friends had a w3 in a box on teh side facing into the cabin. got loud sounded nice, whatever [IMG]i/expressions/face-icon-small-wink.gif[/IMG].
installer came out and suggested turning the box around if possible, said loading agaisnt the wall like that would help with canelations a bit. flipped it and jeez! what a difference!
there is a man online named chris evert, goes by the handle geolemon who once had 4 10's i believe in his civic, he had two on either side facing in. he took plexi glass sheets and experimented with distance, using THAT as a plane to load the woofers. got an improvement, the woofers were firing otherwise into teh middle of nothing.
so even if you had a trunk box firing up, you cna load the woofer if it makes an improvement in sound, just gotta bolt on another panel [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

Rep Power: 0 Interesting, so how come it isn't as good to fire the sub into the trunk cavity to bounce off the other side? Is that too ar of a distance to load? Sounds like to load a plane you need to be within a very near distance, hence diagram B is ideal. Is diagram C too far to load?
What about having the sub face downards to the trunk floor? Would that be another good solution? Is that even feasible?

Rep Power: 338 the questions you are asking, the real answer is i cna quote theory all day long, and it doesnt mean s h i t. the bottom line is you gotta go out and test for yourself [IMG]i/expressions/face-icon-small-smile.gif[/IMG]
i have found personally that if you CANNOT load, then c is the best position. will allow the wave to develop fully in your car.
if you were to place your woofers facing forward sitting on teh back seat, i know that in my car, i cant hear the bass, but 6 cars ahead of me? its nuts!
if you really want to know the best way to load yoru woofer (and downfiring does work in a car, its how i am rebuildign my box) the best thing you can do is build a beater box, and toss it back there, and test for yourself what will sound best and get loudest!
THEN you cna build your nice box with fiberglass, metallic paint, chameleon color changing paint witha vinyl instert, a plexi glass window, and an integrated CD changer and amp rack in an all in one show package that looks and sounds sweet [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

Rep Power: 0 so if I build a down firing box, I was thinking of this or a tire well box, I could put the box up and tilt the subs slightly towards the front of the car but still have them hitting off the floor? this would be almost ideal?

you dont have to make a nice box, or even an MDF box to test! just make a cheapy 5/8 particle board box real quick, will take ya 20 minutes, plus set time, then you can point it in EVERY direction. including facing up sitting where the spare would be [IMG]i/expressions/face-icon-small-smile.gif[/IMG]
then youll know the exact location to get the best sound in yoru civic [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

Well I spent the night moving the sub around and still am not totally sure what sounds best for me. When I do it the traditional way against the back seat pointing towards the back of the car, it sounds good. That's the way I have left it for tonight.
When I aimed it sideways into the sidewalls, like in diagram A or B, it's a bit louder but some notes resonate (I don't know how to describe it). It doesn't sound as good as the traditional way.
When I aim the box straight down into the trunk floor, it's the loudest (given the same gain).

Rep Power: 338 is it possible to prop the box up on books while firing down? so you can get an inch or two of space between teh floor and the woofer?
also, can you try it loading down agasint teh trunk floor on teh metal instead of that flexy wood too? id be curious about teh results of that.....
the slop planeloading to teh side doesnt surprise me one bit, some frequencies will work with teh distance better htan others...... if im right about that then theoretically, changing teh distance you load at teh slop will occur at different frequencies, till you can find a distance/angle where no slop occurs at all......

Rep Power: 0 WhiteRabbit, I have a question for you, since you seem to know quite a bit about these things.
I'm thinking about building my own box for my car. I'm tryint to make it wide as possible so that the box doesn't need to be as deep, so I have have a deeper trunk for cargo. Would that block the bass that's travelling towards the front of the car, or no? Should I go through with this idea, or is it a bad one?

Rep Power: 338 I would think so, but it doesnt. bass knows how to travel. funny how it works. thats why you can see all these systems where teh woofers have seemingly no way of getting sound into teh cabin yet sound so nice......
you dont have to worry at all. even if you do lose some of your pressure (who knows) youll hear it. guaranteed.

Rep Power: 0 I have an SI hatch. the trunk configurations are pretty similar, and what im doing is pretty much B, except the speaker is going to be face up, and tilted towards the rear of the car. The idea is to bounce the soundwaves off of the hatch. You usually want the line of noise, or the path the sound wave travels, to be between 6 and 8 feet from where the driver is sitting. You will hear the best bass right there.
