Face it the direction that makes it the loudest //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I've tried both in my car, facing back, loading off the rear of the car(taillights) was always the loudest for street banging and had better low frequency response!

I couldnt find the site.//content.invisioncic.com/y282845/emoticons/thumbsdown.gif.d22f25895e9b40f2300c953691dacfa2.gif
Im not here to argue either //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

okay, i tried it facing towards the rear, and guess what?
*impatiently waits* What? What? What?
BTW, I think this may have been the site supa was looking for: http://installer.com/tech/aiming.html - just a guess
Interesting article:
SUBWOOFER PLACEMENT
This is usually where we get the most debate and hostility between audiosnobs and those of us that live in the real world. A lot goes on in our mind when processing sound. Since our directional hearing and most sensitive detection occur between 400Hz to about 5kHz, the speakers that produce those frequencies are most important with placement. In fact, most high-end components have only one driver producing those frequencies--one speaker = seamless sound. Keep in mind that at lower volumes we are less sensitive to frequencies above & below that range—making it increasingly hard to satisfy our listener.
Bass, is not that picky. We can place the speakers in front of us, behind us, on top or below. I'd shy away from above & below because in a car, cancellation would be high. Danged acoustics. Since 99.9% of all subwoofers are placed behind the vehicle operator & his/her passengers, let's assume we're all going to put woofers in the trunk or extended cab section.
PS If you have a pick-up and no extended cab, trade it in or sell it at the first opportunity. This will make it easier on the both of us. Thank you.
Bass is like a whip. The closer you get your head to the tip, the harder it's going to hit you. Get too close to the whip, and it'll wrap around you and not hurt at all. This is true in direct proportion to the frequency.
Deeper bass has longer wavelengths. Since sound travels at 643m/s or 1125ft/s in a standard atmosphere, we divide one of the above by the frequency to get the wavelength. Standard atmosphere 20C, 1013mb pressure, 50% relative humidity. A 50Hz wave has a wavelength of 22.5 feet while a 100Hz wave is 11.25 feet.
In order to get the maximum of 50Hz you'd need to get that woofer 22.5 feet away from your head, while 100Hz, only 11.25 feet. This is why we 'hear' the 100Hz sound more prevalently when facing the woofer box towards the vehicle operator when the box is in the trunk. When we face the woofer box towards the trunk, we get the benefit of 3 feet each way via reflection of sound waves.
Since the 50Hz wave gets more time to approach maximum, it appears louder facing backwards than when facing the frontward. Add this with the cabin gain @ 50Hz, and it would appear to be substantially louder. The 100Hz wave is really not affected so dramatically. In fact, there might be some loss in longer vehicles (SUVs Vans, etc) since the wave may be past the 11.25 foot mark, and weakening.
In most cases, placing the woofer box to face the rear of the vehicle will improve frequency response below 60Hz compared to facing it frontward. As long as you have signal processing (EQ or head unit with bass controls) you can compensate for acoustic loss/gain. In most cases, cutting the strongest frequencies (usually 45Hz-55Hz) will balance out the freq resp and at the same time avoid additional distortion caused by over-boosting signal.

i tried facing my sub to the rear of the trunk by the taillights, closed the trunk, let my sub warm up (since it was 20 degrees outside, don't want to be a dumbass and blow the thing, ya know) and played late night tip by Three 6 Mafia, and the bass is alot lower and LOUDER! my neighbor came over to tell me to turn it down lol.

my sub facin backwards in my trunk and its louder(better frequency responce)(way better response), and i tell u what, less ratteles //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

i like this song @ low vol. but @ high vol. it got some excessive bass line that doesnt stop, and i actually hate it. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

i noticed that too HAVINGFUN, the lower the bass the farther u can hear it, like yesterday i heard this car booming bass a block away it was loud inside my house but when i stepped outside to hear it it sounded a little boomier. weird i guess bass travels VERY easily through walls then. just an interesting thing to say from me //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

yeah, when i stand next to my car , its not loud, when i go further , its sounds ldecent. i was playin with tone generator, and noticed that lower frequencies got longer frequencies.

same thing with me Outlaw, u walk away from your car farther and farther away the bass sounds not as loud but when u walk towards it it gets louder and louder and louder! i'ts so cool! any of u guys' tried this?
try it out! it's cool
