I remember back in the day, I used to do the free air systems like this using the kicker subs. It's good to see something like that being done today. I haven't seen this in a long time...
I had 2 MTX "enclosureless" 15s (the grey and pink ones) in an infinite baffle setup back in the early 90s in my 2 door Chevy Cavalier... Ran off a Kenwood 821 amp. That thing slammed for it's time.. Ahh the memories bro.. haha
Great idea when it comes to a seat down trunk build.. fantastic job brother.. not only did you save your trunk space for when you need it but you also saved a ton of time not having to build and tune a box, or having to buy materials.. bravo 👏
I did 4 12” Fi IB subs in a 90’s Cadillac Fleetwood using this method. I went way further though and cut the entire rear deck out and built everything up with MDF and use expanding urethane foam to fill the quarter panels to seal the trunk from the cabin. It played lower than any other system I ever built and only needed 500w per sub. Still my favorite build ever. Not many people know much about infinite baffle designs and there advantages. Well done.
I think since you don't need all the wattage that your amp puts out, running the subs at 4 ohm load would greatly help your S.Q. because most amps run there lowest distortion at 4 ohm... Take the time to completely seal around the edges also. Good video!
@@wilsonrawlin8547 We are talking about subs here, todays monoblock amps are meant to be used at 2 ohms or below, running at 4 ohms is a waste of available power, He is running this at 1.2 ohms. nobody wires subs at 4 ohms??

looking at this video, when i’m finally over my hard hitting 15 in a huge ported box, i’ll definitely try this & get the most out of my 15’s SQ on clean power! i’m sure you purely hear the sub frequencies in the music and no extra rattle or tones!
This really takes me back! Over thirty years ago I did this in a Nissan pulsar with a couple of cheap 12” Crunch. I used a plate that was made for a Camaro and it just happened to fit perfectly behind the back seat. I never even bolted it down lol.
Never done infinite baffle, but my understanding always was they’re great for SQ, less power handling and raw db than other enclosure choices. Your results seem to match that. I’ve hit 135 on 500 watts before but I doubt mine would play as wide a range as an infinite baffle setup would.
I have a box like so many others, works well but there’s always the space issue. IB is definitely getting a hard look. Beautiful and functional solution if you’re into SQ.
Although a large ported box with a low tuning will sound similar with extra headroom in the bass extension, or just adding a pipe that treats the trunk as a slightly leaky ported box and have a 15Hz tuning. The low resonance won't cost you output up higher either compared to the same infinite baffle. Whilst you can use your trunk space, it will restrict the sound a bit.
Way back in 2002 I build a infinite baffle with 2 dvc 100w 12” Realistic subwoofers in my 90 Mazda protégé. It was loud, accurate and clean. Ever since then I’ve always been a huge fan of infinite baffle and T-line builds. With the infinite baffle build you hear the subs not the box
Bruh, your videos are always 🔥mane! Regardless of me doing this back in the eighties, I learn new things everyday fam. I love your video cause their very inspirational to keep me going forward in the car audio game.
Love infinite baffle. Only did it in a vehicle once and it was awesome. Sadly that vehicle was totaled right after I finished the build by fully sealing the baffle with spray foam. I didn’t get to video the final product but there’s a short clip of it unfinished on my channel.
This is a true old school setup. I remember a buddy of mine ran 2 MTX Blue thunder 12" subs in an infinite baffle setup in the back of an old Cavalier - sounded so good to my 15 year old self lol.
I think you did an amazing job showing the difference between SPL and SQL ultimately it’s about the driver and what they wanna hear and you have give a demonstration of just that good work
OMG!!! That sounds so amazing to my ears. I plan to do a set up similar to this in a 2007 Chevy Cobalt sometime soon. I do a lot of traveling and love to listen to my music while doing so. This kind of setup will make my travels so much more pleasurable. The bass wasn't overpowering at all. That's exactly what I wanna have going. Highs, midrange, bass, and finally the sub bass. All working together. Thank you so very much for the video.
Considering how friggin huge even the smallest sealed box is for these drivers, I'm not surprised at all this worked so good. I've done this before WAYYYYYY back and usually had really good results. I would have gone all OCD to make sure there were zero edge leaks and mounted a panel under the rear deck smashing a thick piece of foam in between just to make sure there was no edge leakage. Good job 😁
Glad to be gettin another fun video from you bro! Killer slap together set-up experiment. Imagine if you double baffled, sealed, and dynamatted every thing DAMN!!! 🔊🔊😎
You might could gain a point or two by sealing the baffle with spray foam. Line all surfaces with aluminum foil to protect carpet and such, then foam around perimeter. To answer your question, YES I would do this and actually considered doing it with those subs. Another idea I had was to do a B-pillar wall with 4 single 4ohm 18"s, such as Rockville RVW1800 or Dynavox 18"s. Woofers are about a hunerd bucks a copy and don't need a ton of power to get loud. Thanks for sharing, BudgetBassHead.
To make it more functional you can put a piece of expanded steel mesh across the back (same size as baffle board) and some black grill cloth. Then you can throw anything in the trunk and the subs stay protected.
It can also change the way it sounds , like filling up the trunk with luggage would. Decreasing airspace. Could be better could be worse? Ive never had that car or those particular subs so i wouldnt know. The mesh and cloth would allow air to pass through, but at a much slower rate.
@@JasonWW2000 you have tested this and know 💯 that it wont? I have and aside from what i said the mesh can put runs in the cloth over time from air making the tightly streched cloth vibrate against the metal and unless you attach it in a permanent fashion to the trunk metal its gonna rattle like crazy
Makes me want to try this with my 12's. I'm not running near that amount of power, just a jp8 but just for curiosity sake. Great video, love how excited you sound!
I like your build, but that’s not an infinite baffle. The trunk is the subwoofer box, so it’s more like a sealed chamber, unless of course you leave the trunk open.
& I gotta say…Of all the car audio videos going on out there, I love em all, but I’m always super excited when I see that you put a new one out because I do enjoy your videos immensely. Keep up the great work my friend!
I love the simple look in addition to the retained trunk space. That sounds like a win to me. I remember back in the 80’s and early 90’s that was a pretty common set up. Cerwin Vega made a sub specifically for this application. I believe it was the Cerwin Vega Stealth free air series and they had black surround instead of their classic orange surrounds.
Yes ..Yes.. I did that (cerwin Vega) in 1986 with a 1968 Camaro.. Rockford Fosgate power 650.. pioneer mid & tweet... with a Kenwood pull out cassette radio...fond memories
Did this with two Chevy Novas , the mid 70s sedans. Worked out great. Used double thick baffle, bolted to the metal lip, rear deck braced up as well. Lots of dynamat.
30 years ago I did a IB setup with a couple pioneer 12's in a accord. the main issue was rattling the crap out of the trunk exterior. With the same subs in a 4th order bandpass through the rear deck and it was the most amazing experience. Literally raise your hair with the sunroof open and no rattles on the car 20-80hz. Can't compete with your trunk space though!
@@666Necropsy The first time I tested a dipole sub with some super crappy 12" in a small room, I was instantly amazed because of the details. Even though the sub was totally busted. I kept thinking about it and ultimately got a car that had a trunk that was almost like made for having a sub in the middle. Did an install with good 12" sub and fell in love about the idea where there is no enclosures (for the bass at least). Then after years I got two 18" Electro-Voice DL18MT's, old 90's PA subs for cheap and just fitted them on a big board. I tested them outside, as I'd been dreaming of a sub bass capable small(ish) PA -system that doesn't make the neighbours or anyone living nearby mad (even at like multiple miles away). Nowadays I myself pretty much hate the overly high SPL -oriented cars blasting some single note bass songs nearby. So I can imagine how it would feel waking up or noticing a bumping bass when you're going to sleep that just keeps on playing forever (in your usual forest raves, from 10pm to like 6am+). For example one time we had just one simple big Peavey 2x18" PA sub enclosure and in the beginning of the night a few of my friends went close to the nearest house, more than a mile away (which also was behind a small hill) to check if the bass carries to there and when they got out of the car to listen, they said it sounded like there had been a party going in the nearby house. I've tested the two 18" in a large wooden building and they went nicely down to 20 something Hz. One time I took them to a DJ gig in a really old bar in a wooden building. There I had some problems with uneven bass as I didn't have enough time to EQ the system. I also had a pair of 15" "modern" car subs and they too sounded great outside WITHOUT an enclosure. And I bet the bass couldn't be heard after like 50 meters or so, but the first 10-20 were very nice. Inside an aparment they would shake the floor with Indigo Children (JLE Dub). When I had the system in my car, I noticed that on the outside, the bass seemed to attenuate on the sides of the car, which makes sense as it worked kinda like a dipole. So I think one can blast their music much louder with a free air/infinite baffle sub system than they can with any enclosure without messing with the people around.
Not exactly. It’s not sealed at all. The point of IB is only to keep the front wave separate from the back wave. There’s no air suspension like a sealed box so the driver has to be rated for IB applications.
Once the Q of the system goes down to the Qts of the subwoofer, you have "infinite baffle" even in a box. At that point you just have to deaden and fill the inside of the box to kill reflections. Should play nice right to the Fs of the subwoofer@@rickcharles5667
This is a beautiful simple build! I've always felt like big magnets and high wattage is for loudness, so anything over 10k was for the professionals. For a personal build i focused on a quality full range sound at a decent sustained loudness that's not blowing out my eardrums.
Yo man, I really like all you do. This build brings some ideas to mind. I think a double baffle and brace could improve sturdiness. And just to protect the subs from things in the trunk; leave it open back, but add somewhat of a tunnel box only about 8 inch. Then add vibration deadening to the back side. Just some thoughts, I tinned to over think things.😅
Man this is simply incredible. Well done all around👍🏼 that thing was flexin pretty damn good for an infinite baffle I could only imagine how good it sounds in person.
This is the build, you just take them outside first and set it to 5 and let it rumble the neighborhood with a low vibe; quote a box price of $8000 and from the look on their face adjust the price/bass accordingly. If they wrap their legs around you and kiss ya, then you turn the bass way down of course; all negeotions first before romance....
Fantastic set-up!! The more you seal off the trunk from the cabin, the louder it will be. The combined VAS for those woofers is only 4 cubes shy of the impalas trunk volume. Shoud hit Fs of 24hz, & easily play subsonic frequencies below 20hz with authority!!
I've considered doing an infinite baffle in my rear deck with smaller drivers, only because I need both the trunk space and the passthrough into the cabin to be able to haul stuff around for work. I'm also considering a shallow transmission line mounted to the underside of the rear deck, but I'm concerned about how a shallow, wide line would perform. Those two 18"s look killer, though! Have you played it with the seats up, yet? :D
It sounds like crap with seats up. Almost becomes a fourth order bandpass. Rattles the trunk like crazy, but about a 50% loss of sounds in the cabin. I have to crank the power to hear it properly, which these subs can't handle. I would need the ZVX-18's to play with the seats up.
@BudgetBassHead in my 2015 civic sedan I cut the rear folding arm rest with a ct sounds meso 12 inch Made it custom all the air would travel inside the car . The meso 12 gets extremely low for a box tuned High . Sounds really good
Budget, throw two 18” stereo integrity HT-18s in there Replace the skars with these, I promise you will be amazed , nothing wrong with the skars but the stereo integrity are better and will handle more power (not to mention they cost 199 each) even though on 200 watts they sounded almost as loud as 2000 watts in my build- it’s just and IB thing brother - down low they only need single to double digit wattage to create carnage inside your car……and down low I mean 10-30hz notes 😂 I’m one of the guys that begged you to try IB in the first place so I’m a long time viewer and appreciate your channel. Peace brother
This is legit, never really thought of having the whole trunk as the enclosure. you def need some big speakers and a powerful amp for this build. Did you need to reinforce the trunk more or use dynomat?
you are very wrong, you dont need a ton of power for this, just a good seal and sound deadened cabin, check out ps sounds for these setups, he doesnt even have much power to begin with yet, he can make hair tricks
I have to agree with you Josip. With the lack of compression, a lot of power wasn't really necessary for this build. When given a clean signal, it simply sounds good.
@@BudgetBassHead im having a hard time deciding making a good sounding wind machine against a big heavy box that will just get louder, but not sound as clean, if the infinuite baffle dont sound good, i will still have a baffle to use for a box, weird shape of the trunk is a pain in the ass, id rather just make a strong baffle, run low power and not have to worry about anything, hopefully
Love this, I did the same thing on my BMW, using EVLs 15s. Don't forget to mention that sealing the truck and getting subs with a qts around 0.60 for the best results.
WOW i have some pretty expensive earbuds in and it sounds amazingly awesome I can hear every beat every note everything sounds crystal clear sounds good man that sounds perfect like you said there's no need to throw all the power at it as long as you get what you want from it that's all that matters I give it a 💯 PERCENT 👍🏽👍🏽
i had friends do this back in the day and they would also screw down wood over were the 6x9s would be in the back deck then cut holes in the wood the deck and put 2 pvc ports going in the trunk ya i would do it id put some dyno matt around ware the would is maybe get some of that stuff from homedepot that come in a 4x8 sheet they use on the homes to keep the heat in seal it up and port the deck lid ware the deck speakers are

Man... these are the woofers I wish were made in the late 70's... I was the Baffle Board guy most of the 80's... this sounds great... Nice video. Great explanation... Props. BDBD/2023
SQ is always my go to. SPL sometimes is just straight bass and doesnt appeal to me as much. If you get those sides sealed its pretty much perfect. Saved lots of space too.
I have some old VVX 15's that are collecting dust and a 12" SDR. I see that these are SDR should I attempt this with the 15's or add another 12. My back seat doesn't move but I have a ski pass in my g80.
My first car was a 1978 Monte Carlo. This was in 1992 and I did my system like this. I removed the seat back and mounted two 15" subs in a panel that was sealed as best as possible between the cabin and trunk. Old school "surfboard" amp at 500 watts for the subs and another 250 watts for the mids,highs mounted in a nice flush mount rack right behind the the subs in the trunk. This was in high school. I did a killer upholstery job on the panel so anyone that sat in my back seat leaned against the 15's and waffle grills. The shit banged hard! My Motorola "brick" phone would bounce on the trunk lid. When I rolled up to school or a house party everyone knew I was coming. The car was also slammed with 15x8 reverse deep dish KMC spoons, fresh paint and crushed velour interior! My car would peel those reflectors off the road as I changed lanes. LOL.
My Brother made a "Stealth Shelf" in his 1983 XR4i, basically an Infinite Baffle using the Boot (Truck) space as the Box and fitted 2 6x9's, powered off a Clarion Headunit, this was in 1990 ish and it just sent me down the car audio rabbit hole. I'm still upgrading my daily rides as I replace them!
I built quite many of these IB setups in the past four decades. Yes they do sound smooth, but I've learned a lot about myself since then. I kept burning up the subs/woofers because I kept wanting it louder lol. Many of my friends were satisfied with IB setups because they weren't looking for higher spl. They do sound great tho! Cheers!!
You are basically using your trunk as a big sealed enclosure. The better you seal around the edges of the baffle. The louder it got. Double or tripling up on the baffle and counter sinking them will help in SQ. From what I've found is that an infinite baffle requires a ton of space to unload from. It may be worth testing a single 18 centered with space on both sides. If you could then move it back and forth in the trunk to help get a desired tuning. But then it would be basically free air. It's more practical to design in vans and SUVs.
Exactly what we use to do back in the late 80's to mid 90's in westside in Chicago growing up . Then we go out cruising up and down Chicago listening to classic HOUSE music 😁
Always wanted to do a set up like this my uncle had set like this but had 2×15 can hear it a mile away nice smooth bass that it shakes houses driving by setting car alarm off and loud n clear 6×9 as no rattle from the trunk
What's even more amazing is that I can hear the SQ coming through the recording here. Yes, I have a very good sound system on my computer. Still, the clarity comes through the mic and everything. I drive an SUV so infinite baffle isn't really on the table for me, but I am envious for sure!
This is exactly what i want to do with two HT-18 v3 subwoofers. My enclosure area is a little more tricky then yours is though so im going to have to go to a car audio place that can figure it out because of a hump where the enclosure starts leading into the trunk. I think it can be done though even if its jury rigged to work.
Buddy of mine had 2 12 Pyle pros in a similar set up in a 1980 cutlass supreme , man that was the cleanest bass I ever heard and felt in any car at the time 😎
Great video! Very cerebral. I got rid of my 12" box because i always had to take it out for luggage space. But this solves the problem! Do you ideally want to use subs with tight suspension? What's the name of that parameter?
The two "chambers" should be separated and sealed off completely from each other if you're using your trunk space as the enclosure for the infinite baffle, right?
in Puerto Rico 80's we use to do that a lot too sound just as good 😊
I remember back in the day, I used to do the free air systems like this using the kicker subs. It's good to see something like that being done today. I haven't seen this in a long time...
My pops always talk about the 2 kicker free airs he had in his 79 grand prix... Would love to hear how these sound in person

I love the simple look in addition to the retained trunk space. That sounds like a win to me. I remember back in the 80’s and early 90’s that was a pretty common set up. Cerwin Vega made a sub specifically for this application. I believe it was the Cerwin Vega Stealth free air series and they had black surround instead of their classic orange surrounds.

MTX Eliminators
Yes ..Yes.. I did that (cerwin Vega) in 1986 with a 1968 Camaro.. Rockford Fosgate power 650.. pioneer mid & tweet... with a Kenwood pull out cassette radio...fond memories
Correct....I remember them particular drivers knew someone had a pair in a sealed box in a hatchback an it banged
Did this with two Chevy Novas , the mid 70s sedans. Worked out great. Used double thick baffle, bolted to the metal lip, rear deck braced up as well. Lots of dynamat.
30 years ago I did a IB setup with a couple pioneer 12's in a accord. the main issue was rattling the crap out of the trunk exterior. With the same subs in a 4th order bandpass through the rear deck and it was the most amazing experience. Literally raise your hair with the sunroof open and no rattles on the car 20-80hz. Can't compete with your trunk space though!
that sounds really clean even with youtube audio and your mic. very impressive.
im done with boxes. this is the way to go.
Glad you like it!
@@666Necropsy The first time I tested a dipole sub with some super crappy 12" in a small room, I was instantly amazed because of the details. Even though the sub was totally busted. I kept thinking about it and ultimately got a car that had a trunk that was almost like made for having a sub in the middle. Did an install with good 12" sub and fell in love about the idea where there is no enclosures (for the bass at least).
Then after years I got two 18" Electro-Voice DL18MT's, old 90's PA subs for cheap and just fitted them on a big board. I tested them outside, as I'd been dreaming of a sub bass capable small(ish) PA -system that doesn't make the neighbours or anyone living nearby mad (even at like multiple miles away). Nowadays I myself pretty much hate the overly high SPL -oriented cars blasting some single note bass songs nearby. So I can imagine how it would feel waking up or noticing a bumping bass when you're going to sleep that just keeps on playing forever (in your usual forest raves, from 10pm to like 6am+).
For example one time we had just one simple big Peavey 2x18" PA sub enclosure and in the beginning of the night a few of my friends went close to the nearest house, more than a mile away (which also was behind a small hill) to check if the bass carries to there and when they got out of the car to listen, they said it sounded like there had been a party going in the nearby house.
I've tested the two 18" in a large wooden building and they went nicely down to 20 something Hz. One time I took them to a DJ gig in a really old bar in a wooden building. There I had some problems with uneven bass as I didn't have enough time to EQ the system.
I also had a pair of 15" "modern" car subs and they too sounded great outside WITHOUT an enclosure. And I bet the bass couldn't be heard after like 50 meters or so, but the first 10-20 were very nice. Inside an aparment they would shake the floor with Indigo Children (JLE Dub).
When I had the system in my car, I noticed that on the outside, the bass seemed to attenuate on the sides of the car, which makes sense as it worked kinda like a dipole. So I think one can blast their music much louder with a free air/infinite baffle sub system than they can with any enclosure without messing with the people around.
That’s an insane amount of power for those subs, the trunk becomes a giant sealed box.
Not exactly. It’s not sealed at all. The point of IB is only to keep the front wave separate from the back wave. There’s no air suspension like a sealed box so the driver has to be rated for IB applications.
@@rickcharles5667 True that it’s not totally sealed however it will still be more than if the subs were out in the wide open
Once the Q of the system goes down to the Qts of the subwoofer, you have "infinite baffle" even in a box. At that point you just have to deaden and fill the inside of the box to kill reflections. Should play nice right to the Fs of the subwoofer@@rickcharles5667
Wow dude. This is probably the best sounding system I have heard on yt
Man that sounds clean and precise. Love it 👍
That's badass dude! This is my first time seeing something like this. Sounds great!
This is a beautiful simple build! I've always felt like big magnets and high wattage is for loudness, so anything over 10k was for the professionals. For a personal build i focused on a quality full range sound at a decent sustained loudness that's not blowing out my eardrums.
Works for me. The trunk closed is the box lol. And it wangs
That trunk looks like something audio studio hidden but stills 95% functional!🌹
Yo man, I really like all you do. This build brings some ideas to mind. I think a double baffle and brace could improve sturdiness. And just to protect the subs from things in the trunk; leave it open back, but add somewhat of a tunnel box only about 8 inch. Then add vibration deadening to the back side. Just some thoughts, I tinned to over think things.😅
Saved a TON of work,materials, basic weight issues, and made the unibody a vessel for the subs' chamber. You RIDE the beat❤😂
That's a great way to put it!
Man this is simply incredible. Well done all around👍🏼 that thing was flexin pretty damn good for an infinite baffle I could only imagine how good it sounds in person.
This is the build, you just take them outside first and set it to 5 and let it rumble the neighborhood with a low vibe; quote a box price of $8000 and from the look on their face adjust the price/bass accordingly. If they wrap their legs around you and kiss ya, then you turn the bass way down of course; all negeotions first before romance....
Fantastic set-up!! The more you seal off the trunk from the cabin, the louder it will be. The combined VAS for those woofers is only 4 cubes shy of the impalas trunk volume. Shoud hit Fs of 24hz, & easily play subsonic frequencies below 20hz with authority!!
I've considered doing an infinite baffle in my rear deck with smaller drivers, only because I need both the trunk space and the passthrough into the cabin to be able to haul stuff around for work. I'm also considering a shallow transmission line mounted to the underside of the rear deck, but I'm concerned about how a shallow, wide line would perform.
Those two 18"s look killer, though! Have you played it with the seats up, yet? :D
It sounds like crap with seats up. Almost becomes a fourth order bandpass. Rattles the trunk like crazy, but about a 50% loss of sounds in the cabin. I have to crank the power to hear it properly, which these subs can't handle. I would need the ZVX-18's to play with the seats up.
I have a single 15 hung from my rear deck so I could retain full function of the back seats. I'm not an spl type guy but who doesn't love bass.
My Fairlane show car has four 10's in the rear deck
@BudgetBassHead in my 2015 civic sedan I cut the rear folding arm rest with a ct sounds meso 12 inch Made it custom all the air would travel inside the car . The meso 12 gets extremely low for a box tuned High . Sounds really good
Sounds perfect to my ears. Nice setup. I want something like that in my 07 Monte
Budget, throw two 18” stereo integrity HT-18s in there
Replace the skars with these, I promise you will be amazed , nothing wrong with the skars but the stereo integrity are better and will handle more power (not to mention they cost 199 each)
even though on 200 watts they sounded almost as loud as 2000 watts in my build- it’s just and IB thing brother - down low they only need single to double digit wattage to create carnage inside your car……and down low I mean 10-30hz notes 😂
I’m one of the guys that begged you to try IB in the first place so I’m a long time viewer and appreciate your channel.
Peace brother
With IB, The tradeoff from lower spl is larger bandwidth and incredible lows. Usually plays below 20hz.
I've done that in my home before. The quality of bass is like none other. 2 15s were mounted in my ceiling run by an Adcom GFA-555. :)
I ran a single 18" Fi BTL N2 in an infinite baffle setup in my Audi s4. I agree that infinite baffles are by far the best sounding setups .
This is legit, never really thought of having the whole trunk as the enclosure. you def need some big speakers and a powerful amp for this build. Did you need to reinforce the trunk more or use dynomat?
you are very wrong, you dont need a ton of power for this, just a good seal and sound deadened cabin, check out ps sounds for these setups, he doesnt even have much power to begin with yet, he can make hair tricks
@Aaron_Jones No I didn't apply any 'additional' treatment, just yet. But I do plan to seal the entry a lot better.
I have to agree with you Josip. With the lack of compression, a lot of power wasn't really necessary for this build. When given a clean signal, it simply sounds good.
@@BudgetBassHead im having a hard time deciding making a good sounding wind machine against a big heavy box that will just get louder, but not sound as clean, if the infinuite baffle dont sound good, i will still have a baffle to use for a box, weird shape of the trunk is a pain in the ass, id rather just make a strong baffle, run low power and not have to worry about anything, hopefully
Love this, I did the same thing on my BMW, using EVLs 15s. Don't forget to mention that sealing the truck and getting subs with a qts around 0.60 for the best results.
Try putting all your luggage in there and shortening up the space and then do a test and see what you end up with
That will make a great test. Thanks.
I’d say squeeze the subs together and port it into the cabin
Bro I sure wish I would had this year’s ago with my five hundred. Major props to you
I freaking LOVE my infinite baffle Image Dynamics IDMax 16"
WOW i have some pretty expensive earbuds in and it sounds amazingly awesome I can hear every beat every note everything sounds crystal clear sounds good man that sounds perfect like you said there's no need to throw all the power at it as long as you get what you want from it that's all that matters I give it a 💯 PERCENT 👍🏽👍🏽
Ear buds play low frequency 😂
You got me wanting to do a infinite baffle set up soon! Cool video man!
Boiiii dem ankels ashy asl 😂. Love the video brother 🫶🏿
i had friends do this back in the day and they would also screw down wood over were the 6x9s would be in the back deck then cut holes in the wood the deck and put 2 pvc ports going in the trunk ya i would do it id put some dyno matt around ware the would is maybe get some of that stuff from homedepot that come in a 4x8 sheet they use on the homes to keep the heat in seal it up and port the deck lid ware the deck speakers are
Thanks for the tips.
OMG!!! DUUUH just use your trunk AS A SUB BOX!! THIS IS GENIUS!!! now I wanna do this.
Did they literally just say “sounds better” and show Skar woofers in the same video?! Wow. No words. Just wow.
Is something wrong with skar?
would it not give a similar result if you just had these two in a sealed box the same cubic foot size of the trunk? just curious.
you got more spl from the 5 - 6.5"s
I certainly appreciate you testing this - I may consider even though the 6.5s were more impressive to me
This is actually good because it takes less space in the trunk
I bought a STW350 after extensively watching your videos on it..... I was so excited, saved up for months.... And I will be damned if it didn't get stolen right off my porch man...
Damn porch pirates! Sorry to hear that bro!
Wow. That's horrible. I hate that happened to you.
I ordered & paid $913+ for Skar equipment requested for a signature & leave a call tag if NOT home
FedEx claims they got a signature & left it on my porch
Wtf ?
I live on 110 acres of farm & ranch land & NO neighbors
No one was home
Ring camera NO alerts & NO footage of anyone being at my porch or any FedEx
employees or delivery vehicle
No dam porch pirates
FedEx driver STOLE from me
No recourse with 😊 FedEx, bank or Skar
What resident would sign for it & leave it on the porch ?
new to your channel love the work so far man real clean work old school straight to the point i love it
great video bro..in the 80's I had open air speakers in the trunk in all my car's and pounded so hard like they were in a box.
Was the yellow thing called to cut the board
Old-school way bro yess
Do you remember the kicker free air? Subs? I installed several sets of 15” kicker subs behind the seat of several cutlass’s!!
Man... these are the woofers I wish were made in the late 70's... I was the Baffle Board guy most of the 80's... this sounds great... Nice video. Great explanation... Props. BDBD/2023
How did you match the power with the subs? I’m still learning and from what Iv been told is if your amp is too powerful, it will hurt the subs.
SQ is always my go to. SPL sometimes is just straight bass and doesnt appeal to me as much. If you get those sides sealed its pretty much perfect. Saved lots of space too.
3:29 So the hole at the right is a Bassreflex port?
I wonder what EVL 18s would do in that
Yep 😉
I have some old VVX 15's that are collecting dust and a 12" SDR. I see that these are SDR should I attempt this with the 15's or add another 12. My back seat doesn't move but I have a ski pass in my g80.
My first car was a 1978 Monte Carlo. This was in 1992 and I did my system like this. I removed the seat back and mounted two 15" subs in a panel that was sealed as best as possible between the cabin and trunk. Old school "surfboard" amp at 500 watts for the subs and another 250 watts for the mids,highs mounted in a nice flush mount rack right behind the the subs in the trunk. This was in high school. I did a killer upholstery job on the panel so anyone that sat in my back seat leaned against the 15's and waffle grills. The shit banged hard! My Motorola "brick" phone would bounce on the trunk lid. When I rolled up to school or a house party everyone knew I was coming. The car was also slammed with 15x8 reverse deep dish KMC spoons, fresh paint and crushed velour interior! My car would peel those reflectors off the road as I changed lanes. LOL.
My Brother made a "Stealth Shelf" in his 1983 XR4i, basically an Infinite Baffle using the Boot (Truck) space as the Box and fitted 2 6x9's, powered off a Clarion Headunit, this was in 1990 ish and it just sent me down the car audio rabbit hole. I'm still upgrading my daily rides as I replace them!
Name of the beat u used?
Beat is Damma Beatz - Fast Vision
IB setup's all day over any enclosure.Seal it up better and you're golden.Great job sir 👏🏾
I appreciate that
I built quite many of these IB setups in the past four decades. Yes they do sound smooth, but I've learned a lot about myself since then. I kept burning up the subs/woofers because I kept wanting it louder lol. Many of my friends were satisfied with IB setups because they weren't looking for higher spl. They do sound great tho! Cheers!!
"Something telling me don't do that" truer words have never been spoken 😂
You are basically using your trunk as a big sealed enclosure. The better you seal around the edges of the baffle. The louder it got. Double or tripling up on the baffle and counter sinking them will help in SQ. From what I've found is that an infinite baffle requires a ton of space to unload from. It may be worth testing a single 18 centered with space on both sides. If you could then move it back and forth in the trunk to help get a desired tuning. But then it would be basically free air. It's more practical to design in vans and SUVs.
looks killer in your truck from the front as well as the back great job sir
Exactly what we use to do back in the late 80's to mid 90's in westside in Chicago growing up . Then we go out cruising up and down Chicago listening to classic HOUSE music 😁
Using the trunk as the box is a great idea! I totally dig this. If it works it works
Always wanted to do a set up like this my uncle had set like this but had 2×15 can hear it a mile away nice smooth bass that it shakes houses driving by setting car alarm off and loud n clear 6×9 as no rattle from the trunk
This has always been my go to install for saving my trunk space! Always sounds amazing!
What's even more amazing is that I can hear the SQ coming through the recording here. Yes, I have a very good sound system on my computer. Still, the clarity comes through the mic and everything. I drive an SUV so infinite baffle isn't really on the table for me, but I am envious for sure!
Thanks for noticing. It takes a lot behind the scenes to get you guys good content.
This is exactly what i want to do with two HT-18 v3 subwoofers. My enclosure area is a little more tricky then yours is though so im going to have to go to a car audio place that can figure it out because of a hump where the enclosure starts leading into the trunk. I think it can be done though even if its jury rigged to work.
I like that you spread the word as far as motor size not being a major factor when you have that much cone area
Motor size means the sub will make more power and a bigger motor does more power than a tiny motor with same amount of wattage.
Old school installation!!! Like that setup no doubt. 30hz boom 💥 👌🏼 looks amazing
Buddy of mine had 2 12 Pyle pros in a similar set up in a 1980 cutlass supreme , man that was the cleanest bass I ever heard and felt in any car at the time 😎
10:07 damnnn man 8000! I love this setup and design
Those subs are an awesome basshead bargain bro 👌
Thanks for the content 🙏
No problem 👍
Great video! Very cerebral.
I got rid of my 12" box because i always had to take it out for luggage space. But this solves the problem!
Do you ideally want to use subs with tight suspension? What's the name of that parameter?
The two "chambers" should be separated and sealed off completely from each other if you're using your trunk space as the enclosure for the infinite baffle, right?
Great video
Sweet sub's you got there bro and a Really neat job you did FANTASTIC👌👍🔥🔥🔥
