Years ago I had a 1990 Grand Am with an ADS sub with 2 10’s(sealed). I had worked for many hours tuning the crossovers and levels to get a balanced sound and I had to face the box down and backwards (swivel brackets included). When I sold the car to a teenager he immediately pulled out the 2 10’s and dropped in a Pioneer ported box with 3 12’s facing forward. It took him a couple of hours of frustration to give up and put he ADS box back in and suck up the loss of ego by having 2 10’s instead of 3 12’s. He was in disbelief that I got such a “small box” to sound that good. Interestingly we listened to vastly different music........

I had my 10inch Kicker sub located in the boot facing the boot door. I was not so happy with the depth of the bass. So, I made two changes. One to stuff the port with tight faom to covert it to a sealed box and secondly, moved it to one side of the boot, facing side ways towards the innerside of the boot, rather than facing the back of the car. With these two changes, the bass feels lot more deep and cleaner. Not sure if it due to the sealing or due to the change in direction of the sub or both. Eitherway, happy with the result.
I like it faced upwards because it travels directly into your seating area hence getting more bass, though keeping the frequency higher can mess up listening but on 63hz, I feel it pretty much amazing to hear facing it upwards
Not me looking at the tiny speaker on my phone and understanding how I know that I'm looking at the place the sound is coming from and how my brain is doing it, but this time with more of an understanding of the way it works. This video was extremely informative!! Thank you so much!! I'm doing my first subwoofer and amp install for my car this week and was trying to decide placement in my car for the sub and I think you've helped me make a way more informed decision!!
I've gotten the best spl readings with my subs facing back. That includes a hatchback car, and in a trunk. I used to compete regularly, until some health issues. My greatest hit was in a 2012 Kia Soul, back in 2018, was 147.3 dbs, with the subs facing backwards. Regardless, to each their own.
@@noahon2k906 the wave length of "bass" are longer allowing it to penetrate obstacles with less loss of energy .

Knocking refrigerators over when u come banging down the road requires a s%!+ ton of air movement , which requires many watts and many drivers
Actually it's because most cars with aftermarket stereos simply don't have mids and highs. I hear it all the time on my walks around town,a car will drive by 10 or 15 feet away from me, windows down, and all i hear is "thump....thump thump thump."
Great video! The tiny stock sub was in the rear deck facing down into the truck. The new bigger and much heavier sub is still in the rear deck, but now facing up since that's the only that giant magnet could sit into the original opening.
Another great video from CAF. I'm in the process of acquiring components for my first build and I am using the knowledge gained from these videos to aid in my quest for better sound! Thank you for what you do Mark!
For sure, I have a star 15 in a ported box and had it facing up and it did pound but then I put it facing to the rear right behind the front seats of my blazer and it pounded way harder. Then I put it in the back hatch and it is night and day how hard it hits from the other two ways. Rear facing is definitely where it’s at IMO.
Just curious cause I have a Colorado, what speakers and air space do you have with them. And I'm assuming with the options you had you chose the best sound.

For people in the back firing position I'd first mess around with the box position in the trunk first before changing actual sub facings. I have two mmat monster 12s with a mmat m2000 ($925) pushing them in a ported box with the ports facing front way both in the center with the sub faces on each side of the box (tuned to 32 hz give or take one). I've noticed that if the box is to close to the trunk (right on it) it muffles the bass and causes more rattle because the bass waves dont develop properly that close but i moved the box back about 9 inches from the trunk and just used a piece of half inch wood to keep it in place and the bass quality is like 70% better overall and deeper with minimum rattle at around 35 hz bass tracks. I still have about 3 inches of space left to move the box back more to see if that does anything more.
Facing downward and can be flipped upward. Sealed box.. Can't tell much of a diff. 1 - 10w t3-4 JL Audio shallow. Interesting most people here seam to have ported boxes. Of course I'm old so kinda thought if you can do sealed it's better. Wondering if a ported would be better now for one 10? Thinking prob. Porter is for sure better if there is a lack of air space. Love these videos always so great yo watch.
i aim my sub toward the front bumper. i use to face it toward the rear bumper, but i didnt like it that way, too easy for it to get damaged by something in my trunk. sounds about the same either way. cars a Accord sedan. subs a 12" RE SE (sealed). love that thing ;)
big thumbs up i purchased to 2 knuconcepts kollosal kits 1 for my small sedan which i completely rewired and ill use the other for my mpv suv and i sound deadned all doors and floors firewalls and trunk made 20%sound improvement also purchased audio control lc2i pro for suv also
I have a made to spec sealed downfire box in my sedan with a 10inch hertz es250. Car sounds good and the downfire box provides the safety I need for my subwoofer with the amount of things I load into the vehicle.
I've had my subs face all different ways and can say that there is a huge difference in what direction it faces. I had to face the seat in my sonic because fitting it sideways wasn't an option and it rattled the truck lid to much. Even with foam and dynamat lol
With my old single sealed box just having it Off by a foot would mute the sub lol. Could barely hear it if it wasn't about 8 inches firing back into the hatch of my 06 suburban.
My two 12s are forward facing forward in a sealed box. Never really knew which direction to face them. I just always liked how they looked facing forward!! This was definitely an informative video. Thanks! Looking forward to more on this topic!
My sub faces up into the bottom of my back seat. It’s perfect for my needs. Nice and loud and clear when the seat is up while I’m by myself. Toned down and more ambient when the seat is down for family members to sit.
Car shape and sound deadening must play a huge role. In my 58 Beetle, I installed its third version of a “system” and this single 10” sealed box turned sideways hits harder than either dual 12” sealed box facing forward ever did. Always had only around 400 wattish amps in this car. Something uniques about the shape of a Bug. It sounds like a 1000 watt amp easily
Awesome info. I do car and motorcycle audio. We face our LF woofers and subs firing in from saddlebags under rear fender. This is great information....
I have the krystal kables,like a 4awg wire.awesome and they screw down on the rca's.love em. Have all knu koncepts of 0awg as well.i really is the most flexible ever.great vid. And our 15's are facing upwards and ports to the rear.
When installing my first subwoofer in my car(back in the 1990:s ) I made a box that I tried in different directions to see which was best for my car. I found the best direction was backwards, I was at the time installing in a Saab 900 Hatchback from 1981.
@@MikeCodere23 No, I had a 85 camaro with 2 15inch Orion's and 2, 1.2k wat power amps and crossover i.the box utilized the whole hatch . Speakers faced forward to push the air away .
In my experience facing my 12 towards the rear has a better warmer and deeper response, also putting the sub closest to the back gives you better bass as well
I got my 2 12's (RF P3's) in the trunk of my Mazda 6 facing down. Port blowing through the back seat. Built the box to spec. Sounds great and keeps the sub face from any damage with items that go in the trunk.
I've got a pretty basic setup. A couple skar vd 10s shallow mounts in a downfire box with port forward on a 1200w amp. JbL 3 ohm mids & highs running off pioneer deck. Honestly it's pretty dang impressive for what it is. It'll rattle your teeth loose. Well , I had my back seats up and my box isn't bolted down( shame on me) and my box slid forward just like 2 inches , and I haven't had a chance to really get back there and recreate that situation because I had to shove it back because I started getting a really odd distortion that I think was the sub actually hitting the floor cuz it had slid over a hump in the floor. But before that, OOOOO MAAA GAWD! I don't know what was truly happening but I've never heard it hit so hard. My whole truck I thought was going to fall apart from the vibrations. No lie, it sounded like I had something like 4 12s in some massive box. I'm gonna try to recreate it. Part of me thinks that maybe some sort of phenomenon happened due to wires being pulled around and stuff getting tugged on from box moving, and I wouldn't think that minor of a move and basically not changing the angle at all, would make such a drastic change. It really was incredible. I've been running systems for 20 years and I never seen anything like it.
in my Exeo: -Facing port backwards and putting it close to bootlid = No low rumble -Facing port backwards and pushing it against the back seats = Low rumble but rattling deck -Facing port upwards and pushing it against the back seat = Even more rattle but lacks definition -Facing port forwards and away from backseat = Bass covers everything else
@@worldisDiffirent I had my subs and port facing the bootlid. Sounded the best after tuning the box correctly. On a smaller car like Audi TT i have, making the subs point up was the best.
As long as your box is tuned to the resonance frequency of your vehicle, you should hear the bass all around you. If it's a generic box, you are going to hear the source location of the box. Bass is more omnidirectional than directional. The lower you go, the less you hear and the more you feel. That "feeling" is non locatable. In my 07 Avalanche, I took out the midgate and filled the vertical space with the height of my sealed box with two 10 in subs facing forward. 1800 watt system that pounds so hard that I have to crack the windows so I don't vibrate the windshield too much (had to replace it once already).
I have (a budget setup lol) two Rockford R2D4's in a sealed Atrend box, 1.25 ft³ per chamber on an Audiopipe APCL-3002 in a 2012 Cruze. For a two sub setup, I've always preferred my boxes, sealed or ported, firing backward.
I dig your channel first and foremost. Dude!? Face the sub away or towards me? That’s all I need to know. I took a crash course in sound engineering with no definite answer.
It's also a matter of wave length. Subs as you say have a longer wavelength and will sound better/accurate at the end of that wavelength. The wave extends out facing rear, hits rear of vehicle is reflected forward to your ears. That is closer to a full wave than if sub was facing forward aimed at your ears
I have my two 12's kickers facing sideways (facing to the left of my trunk) in my Sonata. After messing around with them, that is the best location for me and it sounds amazing
Today this video was very helpful. I'm currently making my own custom false floor sub box (and man oh man is your channel a wealth of knowledge to help!). And my dad asked if having it point forward would be better than my intended upwards direction. I told him that with low frequencies it basically didn't matter directionally, like it does with higher frequencies. But my explanation was "it is just known" lol cause I didn't know the actual answer.. But the discussion prompted us to search, and here we are. We were both pleasantly educated, and it settled the discussion that my plan was perfectly fine lol. Great stuff and great channel. I was actually able to explain to him about it being under a solid "false floor" was also ok, because longer (lower) wavelengths are much better at penetrating through objects. It might be slightly muffled vs open, but that's why it'll be removable to show off the sub lol. So I kinda was already on the right track. LOL p.s. posted only a month ago... IT'S LIKE YOU KNEW I WOULD HAVE THIS DISCUSSION o.O (illuminati meme music)
Great knowledge. I have my subs facing up I feel gives the bass a more unrestricted way to travel. Facing backwards in my jeep makes it sound like my panel are shaking hints lowering the actual listening quality.
The sub is inverted. With the sub facing the passenger side ( whole box on drivers side). With the port facing the back. It a logitec z5500 box cleared out with a skar 10 in it. Works good. Sounds good. Always try to face them up though if I want split.
Both subs are facing inward, one facing left from the right and the other facing right from the left both ports facing up. For little 6.5's they sound pretty great good thing to cause that's literally all i can fit in my vehicle.
I’ve read more on this subject lately than any other part of the build and you explained it better than anyone else has. I have a single Infinity Kappa 10 and the best placement I’ve found for SQ in my Civic is facing forward but I also have my trunk closed off with an amp wall. The bass is loud and tight and blends in with the fronts (which are also Infinity Kappas) like it should. I referenced many of your videos during my build and they helped me make decisions to achieve greatness in both build and sound. Keep doing what you do man! Thanks for sharing your knowledge!
I'm currently testing a custom box I designed that has the subwoofers facing the sides of the vehicle. The reason is for more storage in the trunk area since we have kids, and we don't want the subs to be damaged, and I dislike grills. Thanks!
That right there is no joke of a system. I've got three SQL 12s I'm installing facing forward in my Civic SI. The xbl motor design is a whole different animal and worth paying the extra money for if you have a picky ear and don't want to spend as much on massive electrical upgrades. That split gap motor design keeps the BL constant over a much longer stroke than normal subs. So worth it and slayes the drums like none other if you have a picky ear. Just so clean and needs less power to do it.
I have my 2 alpine type x 12s firing towards my taillights, when I position them firing towards the front of my car it hits harder but not as punchy, keep in mind I only have a ski hole in my car the seats don't fold down, also moving them around changes the box rise , everything from moving your driver/ passenger seat changes the performance of your sub. Even a few bags of groceries in my trunk changes the performance.
I have one 10” sub in a slotted box I designed and built. I have a 2006 Toyota Camry. I feel like laying down the back seat and letting the sub fire into the cabin of the car sounds much better.
Right now my subs fire foward ,but the box is way tords ,the very rear of the trunk,port foword, I am testing, so this week ,I will pull the box and fire the subs back and hear the difference between the two, should hit lower back, we will see, love the content mark!!!
I used to have my 10s facing inward in my bandpass box that faced my cabin, next to 2 12s in solo sealed boxes, with rear seats removed in a 96 Saturn sc with Blaupunkt pull out cd faceplate and a mp3 hdd mounted between my sony 4x6s in the rear rear windshield. 14k rms amps with spare battery in the trunk. Sounded terrible to everyone not tone deaf within a mile but great to me!
My personal experience is hatchbacks and especially, wagons sound better with the subs facing back. Sedans and Coupe cars with physically separated trunk areas may sound better firing up, or forward. I bought a sealed box with 12 Kenwoods and a 450 watt amp from a guy who said it sucked, he had it in a Chrysler 300, I put it in my Volvo V70 facing backwards, and it sounds *way* louder in my car, than his. I just tapped in the leads from the rear speakers, with some 25 year old line level adapters, factory head unit, no RCA's, nothing.
Dual JL 10w0v3s with the port and subs facing back. Huge difference. I have it in a Scion FRS with a shit ton of dynomat but I get nothing but rattle from the outside of the car. Sounds awful but the inside isn’t too bad
I'm running 4x kenwood excelon 10's in a sealed 2 cube enclosure. 2 face up 2 face forward. It hits really hard and accurate. Thinking about making a larger sealed enclosure for deeper bass.
Currently sub up port back in a single cab silverado. I'm designing a new console box that will be subs down port up. So it will go from console shaped through middle of truck to truck wedge shape box behind the seats with the port exiting up in the passenger side rear corner. If this is stupid lmk even if you just say "no" lmfao thanks for teaching me. I just started using my router and templates last week.
I keep mine facing the rear. I’ve tried placing them on different positions in my Jeep. Facing up, facing forward, sideways… I’ve found the best lows and punch is when they are rear faced. The only time I found different was in the back of my old Dakota. I had the boxes standing up side by side on the back bench. One forward and one sideways. (2 10” forward and 2 12” sideways). That was something else.
Thanks for the info. You answered my exact question. 🤜🤛 I just got 2 12s and am putting 1000w through em and was just curious what would happen it I moved them around.
I have my subs facing up port up in my suv. If i had the room id face them back but you need at least 4 to 8 inches from the back hatch for that to be effective. I like to put my port as far back to hatch as possible when facing up.
In my ‘83 GMC truck I have a single shallow mount Premier 12” in a sealed box facing forward behind the passenger side of the bench seat. In my 2004 Cadillac XLR I have shallow mount Kenwood Excelon 10” subs mounted in each door.
I’m polish and I design sub goofer the Kurvatech 9900, it don’t matter which direction you put it, 9 million watts of power, best sub goofer in world , like betman .
Another important fact is that by physics, low frequency sounds travel in all directions(even behind the source) while high frequency sounds tend to go in a narrow cone infront of it, and ofcourse our midrange frequencies are inbetween these two, the travel path of the sound is a wider cone. Oh and my sub fires towards the boot.
I used to have my DC Audio Lvl 2 in my trunk close to the rear seat with the port facing towards the taillights but about a month ago I turned it around and moved it near the taillights with port facing towards the front of the car and it hit noticeably deeper.
2002 jeep grand Cherokee. 1 audiopipe bd2 12 in a 2.4 cubic foot slot ported cabinet. Performs very well for what it is but looking at a pair of new subs so upgrades are potentially in the works
The two loudest and best sounding systems I've ever heard in my life were both oriented this way. The old '80s Toyota hatchbacks were amazing for acoustics. My buddy Chris had four 10-in kicker still Waters running them ported in his 86 super hatchback and it was difficult to sit in while being crystal clear
Came into this to know which way to face my sub, left with 5 credits towards my engineering degree.

Facing downward and can be flipped upward. Sealed box.. Can't tell much of a diff. 1 - 10w t3-4 JL Audio shallow.
Interesting most people here seam to have ported boxes. Of course I'm old so kinda thought if you can do sealed it's better. Wondering if a ported would be better now for one 10? Thinking prob. Porter is for sure better if there is a lack of air space. Love these videos always so great yo watch.
I love the way this Brother breaks down sound... Great Video and content.
i aim my sub toward the front bumper. i use to face it toward the rear bumper, but i didnt like it that way, too easy for it to get damaged by something in my trunk. sounds about the same either way. cars a Accord sedan. subs a 12" RE SE (sealed). love that thing ;)
big thumbs up i purchased to 2 knuconcepts kollosal kits 1 for my small sedan which i completely rewired and ill use the other for my mpv suv and i sound deadned all doors and floors firewalls and trunk made 20%sound improvement also purchased audio control lc2i pro for suv also
I have a made to spec sealed downfire box in my sedan with a 10inch hertz es250.
Car sounds good and the downfire box provides the safety I need for my subwoofer with the amount of things I load into the vehicle.
I've had my subs face all different ways and can say that there is a huge difference in what direction it faces. I had to face the seat in my sonic because fitting it sideways wasn't an option and it rattled the truck lid to much. Even with foam and dynamat lol
With my old single sealed box just having it Off by a foot would mute the sub lol. Could barely hear it if it wasn't about 8 inches firing back into the hatch of my 06 suburban.
My two 12s are forward facing forward in a sealed box. Never really knew which direction to face them. I just always liked how they looked facing forward!! This was definitely an informative video. Thanks! Looking forward to more on this topic!
Turn that box around
Love it.
Not about looks it's all about booming
@@djkeys415s punking that Boi 🤣😂😆
My sub faces up into the bottom of my back seat. It’s perfect for my needs. Nice and loud and clear when the seat is up while I’m by myself. Toned down and more ambient when the seat is down for family members to sit.
I have 2 10s facing upwards in my 2017 mustang and they sound really good .
Car shape and sound deadening must play a huge role. In my 58 Beetle, I installed its third version of a “system” and this single 10” sealed box turned sideways hits harder than either dual 12” sealed box facing forward ever did. Always had only around 400 wattish amps in this car. Something uniques about the shape of a Bug. It sounds like a 1000 watt amp easily
Awesome info. I do car and motorcycle audio. We face our LF woofers and subs firing in from saddlebags under rear fender. This is great information....
I have the krystal kables,like a 4awg wire.awesome and they screw down on the rca's.love em.
Have all knu koncepts of 0awg as well.i really is the most flexible ever.great vid.
And our 15's are facing upwards and ports to the rear.
I had/will have a 12 inch JBL in the trunk of my Versa facing away from me. Haven't really tested that much into it but it honestly looks the coolest
Mark you have literally taught me everything I use now. Thank you so much for helping me become better at my favorite hobby
When installing my first subwoofer in my car(back in the 1990:s ) I made a box that I tried in different directions to see which was best for my car. I found the best direction was backwards, I was at the time installing in a Saab 900 Hatchback from 1981.
Didn't all hatchbacks have better and cleaner sound facing the back?
@@MikeCodere23 No, I had a 85 camaro with 2 15inch Orion's and 2, 1.2k wat power amps and crossover i.the box utilized the whole hatch . Speakers faced forward to push the air away .
Was wondering if this is Brian Love ? 🤔
In my experience facing my 12 towards the rear has a better warmer and deeper response, also putting the sub closest to the back gives you better bass as well
I got my 2 12's (RF P3's) in the trunk of my Mazda 6 facing down. Port blowing through the back seat. Built the box to spec. Sounds great and keeps the sub face from any damage with items that go in the trunk.
I think mine being on the roof works really well tbh 👌🏾 great vibrations
im gonna get mine there now
@@tebogompete7530 Strap it down tho
Man what a good lesson this video was, thanks!
WOW, this was incredibly informative. Very well done
I have 2 12’s in a ported box, facing up. 1200w rms in a 07 Sequoia! 👌🏽
I've got a pretty basic setup. A couple skar vd 10s shallow mounts in a downfire box with port forward on a 1200w amp. JbL 3 ohm mids & highs running off pioneer deck. Honestly it's pretty dang impressive for what it is. It'll rattle your teeth loose.
Well , I had my back seats up and my box isn't bolted down( shame on me) and my box slid forward just like 2 inches , and I haven't had a chance to really get back there and recreate that situation because I had to shove it back because I started getting a really odd distortion that I think was the sub actually hitting the floor cuz it had slid over a hump in the floor. But before that, OOOOO MAAA GAWD! I don't know what was truly happening but I've never heard it hit so hard. My whole truck I thought was going to fall apart from the vibrations. No lie, it sounded like I had something like 4 12s in some massive box.
I'm gonna try to recreate it. Part of me thinks that maybe some sort of phenomenon happened due to wires being pulled around and stuff getting tugged on from box moving, and I wouldn't think that minor of a move and basically not changing the angle at all, would make such a drastic change. It really was incredible. I've been running systems for 20 years and I never seen anything like it.
If you have the port facing the rear, it'd get even louder.
i have one facing up and another facing back, idk if its not good or whatever but it bumps good so I like it
It’s crazy how much of a difference it makes
in my Exeo:
-Facing port backwards and putting it close to bootlid = No low rumble
-Facing port backwards and pushing it against the back seats = Low rumble but rattling deck
-Facing port upwards and pushing it against the back seat = Even more rattle but lacks definition
-Facing port forwards and away from backseat = Bass covers everything else
So what's the best way to face them
@@worldisDiffirent I had my subs and port facing the bootlid. Sounded the best after tuning the box correctly. On a smaller car like Audi TT i have, making the subs point up was the best.
@StaticVapour590 ok do u think I can try facing mines up I'm running 1 15sub on a 4000amp but I drive a 4 door charger
As long as your box is tuned to the resonance frequency of your vehicle, you should hear the bass all around you. If it's a generic box, you are going to hear the source location of the box. Bass is more omnidirectional than directional. The lower you go, the less you hear and the more you feel. That "feeling" is non locatable. In my 07 Avalanche, I took out the midgate and filled the vertical space with the height of my sealed box with two 10 in subs facing forward. 1800 watt system that pounds so hard that I have to crack the windows so I don't vibrate the windshield too much (had to replace it once already).
How do I find the response frequency of my vehicle?
I have (a budget setup lol) two Rockford R2D4's in a sealed Atrend box, 1.25 ft³ per chamber on an Audiopipe APCL-3002 in a 2012 Cruze. For a two sub setup, I've always preferred my boxes, sealed or ported, firing backward.
Cqme for something, left as an engineering and Physics expert. Proud moment😊
1 JLW3 2 ohm 12" ported centered on backseat of truck facing forward. Port facing passenger door. Sounds the best.
I dig your channel first and foremost. Dude!? Face the sub away or towards me? That’s all I need to know. I took a crash course in sound engineering with no definite answer.
Always facing outward for me. Actually right now I have 1 12 facing up and 1 facing the back. Banger.
Salute always blessings to all the incredible grind and motivation....
It's also a matter of wave length. Subs as you say have a longer wavelength and will sound better/accurate at the end of that wavelength. The wave extends out facing rear, hits rear of vehicle is reflected forward to your ears. That is closer to a full wave than if sub was facing forward aimed at your ears
Good way to explain that
I have my two 12's kickers facing sideways (facing to the left of my trunk) in my Sonata. After messing around with them, that is the best location for me and it sounds amazing
My F150 Supercrew truck: sealed box under rear seat, subs down-firing . Wife's Fusion: ported box in the trunk facing directly up
Thanks for answering! Yes trucks can sound great that way or with subs facing forwards oddly enough.
Today this video was very helpful. I'm currently making my own custom false floor sub box (and man oh man is your channel a wealth of knowledge to help!). And my dad asked if having it point forward would be better than my intended upwards direction. I told him that with low frequencies it basically didn't matter directionally, like it does with higher frequencies. But my explanation was "it is just known" lol cause I didn't know the actual answer.. But the discussion prompted us to search, and here we are. We were both pleasantly educated, and it settled the discussion that my plan was perfectly fine lol. Great stuff and great channel.
I was actually able to explain to him about it being under a solid "false floor" was also ok, because longer (lower) wavelengths are much better at penetrating through objects. It might be slightly muffled vs open, but that's why it'll be removable to show off the sub lol. So I kinda was already on the right track. LOL
p.s. posted only a month ago... IT'S LIKE YOU KNEW I WOULD HAVE THIS DISCUSSION o.O (illuminati meme music)
Great info.
I have a free air setup and they aim up through the hatchback shelf
Great knowledge. I have my subs facing up I feel gives the bass a more unrestricted way to travel. Facing backwards in my jeep makes it sound like my panel are shaking hints lowering the actual listening quality.
The sub is inverted. With the sub facing the passenger side ( whole box on drivers side). With the port facing the back. It a logitec z5500 box cleared out with a skar 10 in it. Works good. Sounds good. Always try to face them up though if I want split.
Both subs are facing inward, one facing left from the right and the other facing right from the left both ports facing up.
For little 6.5's they sound pretty great good thing to cause that's literally all i can fit in my vehicle.
Sealed under my F150 back seat, upfiring!!!
Nice! Funny how that can still sound great with the bass frequency sound, but now we know why!
Liked because of the dog head turning fact:)
I’ve read more on this subject lately than any other part of the build and you explained it better than anyone else has. I have a single Infinity Kappa 10 and the best placement I’ve found for SQ in my Civic is facing forward but I also have my trunk closed off with an amp wall. The bass is loud and tight and blends in with the fronts (which are also Infinity Kappas) like it should. I referenced many of your videos during my build and they helped me make decisions to achieve greatness in both build and sound. Keep doing what you do man! Thanks for sharing your knowledge!
2 12's and port facing forward, in a hatchback, I get better lows this way. I tried back and up. Just sounds much better forward.
i had 3x 12's in a hatchback once. Found facing them backwards gave a better sound. sealed. Faced backwards ever since.
I'm currently testing a custom box I designed that has the subwoofers facing the sides of the vehicle. The reason is for more storage in the trunk area since we have kids, and we don't want the subs to be damaged, and I dislike grills. Thanks!
You said "doo-doo".
Love your videos.
18” Stereo Integrity HST sealed facing forward. Removed the smaller side of my rear seat. Prior I had 2 Illusion C10 down firing under the rear seat.
That right there is no joke of a system. I've got three SQL 12s I'm installing facing forward in my Civic SI. The xbl motor design is a whole different animal and worth paying the extra money for if you have a picky ear and don't want to spend as much on massive electrical upgrades. That split gap motor design keeps the BL constant over a much longer stroke than normal subs. So worth it and slayes the drums like none other if you have a picky ear. Just so clean and needs less power to do it.
I have my 2 alpine type x 12s firing towards my taillights, when I position them firing towards the front of my car it hits harder but not as punchy, keep in mind I only have a ski hole in my car the seats don't fold down, also moving them around changes the box rise , everything from moving your driver/ passenger seat changes the performance of your sub. Even a few bags of groceries in my trunk changes the performance.
Bitd floor pan installed subs were the rage in car audio magazines. Yes, I referenced a magazine lol
I have one 10” sub in a slotted box I designed and built. I have a 2006 Toyota Camry. I feel like laying down the back seat and letting the sub fire into the cabin of the car sounds much better.
Right now my subs fire foward ,but the box is way tords ,the very rear of the trunk,port foword, I am testing, so this week ,I will pull the box and fire the subs back and hear the difference between the two, should hit lower back, we will see, love the content mark!!!
Wow man i really wait for your next video.
I used to have my 10s facing inward in my bandpass box that faced my cabin, next to 2 12s in solo sealed boxes, with rear seats removed in a 96 Saturn sc with Blaupunkt pull out cd faceplate and a mp3 hdd mounted between my sony 4x6s in the rear rear windshield. 14k rms amps with spare battery in the trunk. Sounded terrible to everyone not tone deaf within a mile but great to me!
Think you could do a video on building a test bench. With a list of recommended components and walk through.
Have a great weekend ✌️.
You too!
Highly informative as always
Glad you think so! Thanks for watching!
My sub is firing upwards, because that's the only way I could fit a 15 in my trunk
Same mine is under seat. 66 Toyota Land Cruiser
My 415s is facing up. Only way
My 5" is facing front.
Rear facing port.
Why you laughing ?
My 2 tens are facing upwards I feel like they sound better that way then facing towards the back like towards the twilight's.
My personal experience is hatchbacks and especially, wagons sound better with the subs facing back. Sedans and Coupe cars with physically separated trunk areas may sound better firing up, or forward. I bought a sealed box with 12 Kenwoods and a 450 watt amp from a guy who said it sucked, he had it in a Chrysler 300, I put it in my Volvo V70 facing backwards, and it sounds *way* louder in my car, than his. I just tapped in the leads from the rear speakers, with some 25 year old line level adapters, factory head unit, no RCA's, nothing.
98 K1500 Ext Cab. Sealed Box behind the driver's seat downfiring. Sounds great to me.
Dual JL 10w0v3s with the port and subs facing back. Huge difference. I have it in a Scion FRS with a shit ton of dynomat but I get nothing but rattle from the outside of the car. Sounds awful but the inside isn’t too bad
I'm running 4x kenwood excelon 10's in a sealed 2 cube enclosure. 2 face up 2 face forward. It hits really hard and accurate.
Thinking about making a larger sealed enclosure for deeper bass.
yes hiiii, i wanted to know this as well
Currently sub up port back in a single cab silverado. I'm designing a new console box that will be subs down port up. So it will go from console shaped through middle of truck to truck wedge shape box behind the seats with the port exiting up in the passenger side rear corner. If this is stupid lmk even if you just say "no" lmfao thanks for teaching me. I just started using my router and templates last week.
I keep mine facing the rear. I’ve tried placing them on different positions in my Jeep. Facing up, facing forward, sideways… I’ve found the best lows and punch is when they are rear faced. The only time I found different was in the back of my old Dakota. I had the boxes standing up side by side on the back bench. One forward and one sideways. (2 10” forward and 2 12” sideways). That was something else.
Thanks for the info. You answered my exact question. 🤜🤛 I just got 2 12s and am putting 1000w through em and was just curious what would happen it I moved them around.
I have my subs facing up port up in my suv. If i had the room id face them back but you need at least 4 to 8 inches from the back hatch for that to be effective. I like to put my port as far back to hatch as possible when facing up.
In my ‘83 GMC truck I have a single shallow mount Premier 12” in a sealed box facing forward behind the passenger side of the bench seat.
In my 2004 Cadillac XLR I have shallow mount Kenwood Excelon 10” subs mounted in each door.
I’m polish and I design sub goofer the Kurvatech 9900, it don’t matter which direction you put it, 9 million watts of power, best sub goofer in world , like betman .
Sealed, dual chamber, down facing, under seat box with two 10" alpines. Crew cab F150 with a rear seat lift of about 1.38 inches.
I have two Kicker L7S 12's down firing in a sealed 3.8 cubic feet 3/4" birch enclosure.
Another important fact is that by physics, low frequency sounds travel in all directions(even behind the source) while high frequency sounds tend to go in a narrow cone infront of it, and ofcourse our midrange frequencies are inbetween these two, the travel path of the sound is a wider cone. Oh and my sub fires towards the boot.
I used to have my DC Audio Lvl 2 in my trunk close to the rear seat with the port facing towards the taillights but about a month ago I turned it around and moved it near the taillights with port facing towards the front of the car and it hit noticeably deeper.
2002 jeep grand Cherokee. 1 audiopipe bd2 12 in a 2.4 cubic foot slot ported cabinet. Performs very well for what it is but looking at a pair of new subs so upgrades are potentially in the works
Usually cars that already come with professional audio systems the sub is usually located either under the trunk flooring or left or right rear panels
I got two 15" subs in a 2019 hyundai veloster. Facing backwards. Hatchback trunk makes the car shake. Beautiful bass.
Non ported facing towards u is very very responsive and accurate bass and is still able to slam
Sub and port facing up in a hatchback. Tried several positions but this orientation sounded best.
Awesome! Its funny how you would think that it would need to face at you, but as we learned in this video it does not!
The two loudest and best sounding systems I've ever heard in my life were both oriented this way. The old '80s Toyota hatchbacks were amazing for acoustics. My buddy Chris had four 10-in kicker still Waters running them ported in his 86 super hatchback and it was difficult to sit in while being crystal clear
Yes, my subwoofer was facing the wrong way. Corner loading in my civic was the way to go but in my sentra now its rear facing and its quite noticable.
