LOVE this video!!!!!! I'm going to use it every damn time I try to explain this to someone & they don't understand different vehicle different results!
Conclusion, The response from vehicle to vehicle was completely opposite, Grand marquis: 139.3db peak @ the 34hz then tapers down to about a 135db at 49hz, Then the escalade: 136.2 @ 34hz and gains all the way through 49hz. Just wanted to show how drastically one vehicle can respond from another! Let me know what you think about this experiment! www.GPcarAudio.com
www.GPcarAudio.com Great idea! Did you see if the score is higher with the enclosure closer to the hatch or backed up against the rear of the rear seat, but still facing towards the rear? Maybe a frequency change like that?
What's up man, I kept this relatively simple and had them loading about 6 inches from the rear hatch. Typically on a setup this small in that large of a vehicle the loading off the hatch is very important for the sound getting to the dash. On past builds with this style of enclosure configuration the further away from the hatch the lower the score. To really take advantage of what is possible on the 6.5"s in that vehicle ( if spl is the only concern) its best to tune up around 45hz subs up port back.
If you are chasing numbers tuning higher will almost always easily reward you with a higher number on the dash. This can vary per vehicle the installation is going in. You just have to remember, the higher you tune the less musical the system can be.
This is one of the biggest things people overlook, as well as me! I have a 2000 civic coupe and my system in there seems to like the mid to upper 40 hz range and I thought my system wasnt good for the lower bass notes, I put my system in an 09 impala and it got DOWN! And that was with my amp that still seemed to struggle on the lower side of bass, and with my other amp it got even lower! Was much louder and hit so much deeper, inside the car it didnt sound anywhere CLOSE to the same system! Its not always about the equipment, the vehicle makes just as big of difference as the system itself!!!
This is CRAZY!! I was just EXPLAINING this to a friend. SAME SET UP ( 2 A.A. CHAOS 12'S/VFL amp), moved from my Volvo to Caravan 2db gain. More air space to fill, and a higher score? Doesn't make sense but, YES!!! Definitely will be sharing this video ALOT!
lower frequency waves have more time to mature in bigger vehicles but real lows fall away cause the wave length is bigger than the actual vehicle and the flex adds a harmonic and tends to cancel the lows out
hittin-low_150db+ . FOR SURE BRO. I get it but, it's ALOT EASIER to share this video, then trying to explain that to a newbie who just wants to bump around the neighborhood.
Thank you! I have been waiting for someone to post a video on this topic! I have some questions of my own. I used to have my single 12” Sundown Audio in a box built to spec (2 cubic feet tuned to 35 Hz with sub back & port back) in a 2001 Toyota Camry. It KILLED the lows, peaking somewhere in the 30 Hz range, but the higher bass notes, such as the 50s, were not as prominent. When I moved the EXACT same setup into a 2004 4Runner, I noticed a massive decrease in the lows that I once had & loved in the Camry, but the higher bass notes - which I do not care nearly as much for - were more authoritative. I have tried moving my enclose into numerous different positions, but I have been unsuccessful in achieving the same kind of soul-shaking lows like I once had in the Camry. Like I mentioned, my current enclosure is built to spec, so do I need to build a different enclosure to achieve the same kind of lows? Would building an enclosure with the sub up and port back make a difference? Do I need to build an enclosure that is tuned lower? Do I need to add a second subwoofer? Or is there no way to work around the dynamics of the 4Runner? I really, really miss the lows I had in my Camry & am at a loss on how to get them back in the 4Runner, so any input would help! Thank you for your time & patience!
Yup, this video is to get across to the majority, can't tell you how many times someone with a SUV gives advice to someone with a car and its a total flop. Hopefully this will help people be more careful on the advice they absorb. Down the road we will start getting more technical and share some tricks. There is also so many more variables. I will work on covering them all.
Correct me if I'm wrong my dear friend and brother Tyler. You'd get a totally different tuning in a different sounding as well your not going to get the same numbers in a different vehicle.
What's up man, the tuning remains the same on the enclosure (34hz), the goal in this video is to show how different the same system can perform from one vehicle to another. And yes correct, the playable bandwidth measurements were almost opposite from vehicle to vehicle. The Grand Maruis- 139.3 at 34 hz and fades down to about a 135 at 50hz, where the escalade 136.2 at 34hz gains all the way through 49hz (140.6)
You know what’s crazy, my alpine SWS-15D4 in 1.35 cu.ft. sealed box is louder in my my 2018 mustang when comparing it to when it was in a 3 cu.ft. ported box in my 2006 Ford Focus 4 door. Crazy how the car and box combo can make or break a system! I am only pushing this sub with a alpine mrv-m500 as well!
Yup! speaking of mustangs, Our budget chevy cobalt build back in the day, single 10 on 600 watts, did a 138 somthing in the cobalt, I took that system out (amp sub and box) and put it in my stepson's mustang, with all settings exactly the same, his peak went to 62hz and did a 142, literally nothing different at all, just the vehicle. That was my original motivation to make this video just took me a while.
www.GPcarAudio.com Awesome! Always interesting to hear others stories and history with experiences. My favorites setup thus far is in my mustang. Stock headhnit and speakers. Added the sub and amp and it sounds amazing. Bass isn’t overwhelming either.
My 99 grand Cherokee is perfect for my 2 American bass xr 12s with 2 ab amps pushing 1500+ rms to each is just right for me? Love this video alphard audio rules
Where is your location to get work done?.. I have a jeep I want you to thro subs in. Or how can I get in contact with you about work I want done. Thanks
My hearse with 2 15's likes low frequencies 32hz and under probably because the subwoofers are 12 teet behind you. My truck walled with 4 18's likes 54 hz kick drums rock in my truck lol
Hi bro, i need to ask a question about this topic, cuz i had designed a box for a single 12" pioneer sub 1400 watt max and this box is tuned to 23 hz, but unfortunately the box isn't even playing 30 hz loud and clean, and everything below 29 hz can't be heard, u can only hear the mechanical noise of the the sub, could the vehicle be the reason behind this failure ??? Thx in advance sir and great video by the way, keep up the good work 😊😊
What's up man, there is a lot of variables here, 23hz is also an extremely low tune and there is not a lot of music out there to play on that with the range of play it would have with that low of a tune,. It sounds like maybe its tuned up around 36-40hz if 29hz and down is not audible, but again so many variables, you could be having cancellation issues, all the way to a possible error on the enclosure.
www.GPcarAudio.com well I know that 23 hz is a very low freq. but when it comes to music, I have a lot, used to download modified bass songs before they removed them like decaf, djsnt, djdb,... etc, anyway, what i need u know is that many experts told me that this can be due to the cheap sub that am using, but this doesn't make sense I guess, so what u think bro ??
Not true at all i mean some subs will sound a lot better with the lows but you should still be able to hit below 30hz strong if your box is tuned to 23hz. My box is tuned to 30hz and i play down to 25hz full tilt and it sounds amazing i hate anything above 30hz.
Question. I own a Tahoe and run 2 psi 18's platform 3 on 3k. I am having issue with getting the right requency response in it. U said 49ish ok what would be the ideal port tune in a 9ft3 ported box. Subs up port rear fire. I've been playing with it for awhile. Port is now 36hrtz with 1.09ft port volume
yeah standing wave occours around 49hz yo build a box 1 octave tuning lower than the peak and tell me how it plays in the tahoe...should be perfectly flat
So years ago, I had a powerbass 15" (the good powerful ones) in my explorer. 1500 watts. It sounded okay. Put it in my buddies expedition and it was a world of difference. It was dropping stuff off his roof and knocking the windows off track. Didn't do that in my explorer. Now that I learned a lot since about 10 years ago, I'm assuming his truck peaked a whole lot lower than mine
Im glad you replied lol .. its not I likely made this comment with out actually reading everything first.. or I was slightly inebriated it happens from time to time.
In a ported enclosure, It depends on the driver and how much power you have. Typically you can manipulate larger gains by going larger on the enclosure, you just have to be sure your port velocity is dialed in correctly.. The larger you go the more "peaky" the enclosure will be, but if your're just going for numbers, thats not an issue, just have to be careful what you play and learn the playable range of frequencies.
Not necessarily, remember we are tuned very low for 6.5"s so we have a lot going against us here. A sub up port back box tuned up around 45 hz in that escalade would do some crazy numbers.
in the tahoe's/ denali's/ and escalades, cargo area builds under the window line subs up port back has always yielded the easiest numbers. It has to do with how everything loads in the cargo area.

www.GPcarAudio.com I'm shocked those 6.5's did so well! Good stuff man!
www.GPcarAudio.com so to have much better output from your subs the box has to be tune higher frequency or what
If you are chasing numbers tuning higher will almost always easily reward you with a higher number on the dash. This can vary per vehicle the installation is going in. You just have to remember, the higher you tune the less musical the system can be.

Yup, the variance can be drastic.

Buick Regal . NOPE , BACK SEATS FOLD DOWN, SUBS AND PORT FACING IN, ALMOST A WALL JUST NOT SEALED YET. It's all on my Channel. check it out bro
Great to see these type of test video's! Especially with 6 1/2's

had my pioneer 10" shallow mounts in 3 different trucks powered with same amp, same box. as the cab size got larger the subs sounded better.
Just for fun...what about a single cab build? I'm thinking of going with (4) 6.5 DD 506
Definitely always used subs up, big ass port to the side in my suv at 33 hz. Seems to do well. Definitely learned something new. Thanks.
No problem
ITS ALL ABOUT PHYSICS AND HOW THE SOUND WAVES REFLECT IN THE VEHICLES
Yup, this video is to get across to the majority, can't tell you how many times someone with a SUV gives advice to someone with a car and its a total flop. Hopefully this will help people be more careful on the advice they absorb.

I think ported boxes are more compatible for cars...sealed for trucks
This guy looks like the exterminator from over the hedge
How about some tips for working with and around this vehicle response, how can we optimise our tuning and outcome for a specific vehicle?
I love the knowledge you guys always drop!🔥
Thanks!
You know what’s crazy, my alpine SWS-15D4 in 1.35 cu.ft. sealed box is louder in my my 2018 mustang when comparing it to when it was in a 3 cu.ft. ported box in my 2006 Ford Focus 4 door. Crazy how the car and box combo can make or break a system! I am only pushing this sub with a alpine mrv-m500 as well!
Yup! speaking of mustangs,
Our budget chevy cobalt build back in the day, single 10 on 600 watts, did a 138 somthing in the cobalt,
I took that system out (amp sub and box) and put it in my stepson's mustang, with all settings exactly the same, his peak went to 62hz and did a 142, literally nothing different at all, just the vehicle.

Awesome! Always interesting to hear others stories and history with experiences. My favorites setup thus far is in my mustang. Stock headhnit and speakers. Added the sub and amp and it sounds amazing. Bass isn’t overwhelming either.
Aw man this whole time i thought i was subscribe'd - welp just did!
My 99 grand Cherokee is perfect for my 2 American bass xr 12s with 2 ab amps pushing 1500+ rms to each is just right for me? Love this video alphard audio rules
Nice video
Thanks!
Great video!
Thank you
How can't I buy 1 subwoofer box like this one for my 2004 crown victoria
What type of amp was running the three 6.5's
Very informative video!
Thanks
Am looking into getting subs for my corolla 04 but not sure if you guys will assist me I’m in Indy
What's up man? Give us a call on Monday and we can go over your goals and get you fixed up proper.
Thanks for the share!
no problem
I need some specs for a three 10 inch box please someone .
Pressure
Where is your location to get work done?.. I have a jeep I want you to thro subs in. Or how can I get in contact with you about work I want done. Thanks
Also try using different sized subs thats where the difference lies
my corolla peak in the 30's as well.
My hearse with 2 15's likes low frequencies 32hz and under probably because the subwoofers are 12 teet behind you. My truck walled with 4 18's likes 54 hz kick drums rock in my truck lol
On wish vehicle by ear wish one sound it louder on the car or suv
awesome 👍
Hi bro, i need to ask a question about this topic, cuz i had designed a box for a single 12" pioneer sub 1400 watt max and this box is tuned to 23 hz, but unfortunately the box isn't even playing 30 hz loud and clean, and everything below 29 hz can't be heard, u can only hear the mechanical noise of the the sub, could the vehicle be the reason behind this failure ???

Your box definitely isnt tuned to 23hz you would slam 20-30hz especially if you are playing 29hz and it just sounds like air.
crunkjuice29 that is what supposed to happen, bro, I heard that some subs brands especially the cheap ones can't go to 20 hz, is that right ??
Not true at all i mean some subs will sound a lot better with the lows but you should still be able to hit below 30hz strong if your box is tuned to 23hz. My box is tuned to 30hz and i play down to 25hz full tilt and it sounds amazing i hate anything above 30hz.
Question. I own a Tahoe and run 2 psi 18's platform 3 on 3k. I am having issue with getting the right requency response in it. U said 49ish ok what would be the ideal port tune in a 9ft3 ported box. Subs up port rear fire.
I've been playing with it for awhile. Port is now 36hrtz with 1.09ft port volume
dan daves your problem is that box is way to small for 18s u will need around the 14cube mark
It is 14.4ft3 before braceing n port
Sorry 13.4
yeah standing wave occours around 49hz yo build a box 1 octave tuning lower than the peak and tell me how it plays in the tahoe...should be perfectly flat
Good info bro but real bassheads already know this,
So years ago, I had a powerbass 15" (the good powerful ones) in my explorer. 1500 watts. It sounded okay. Put it in my buddies expedition and it was a world of difference. It was dropping stuff off his roof and knocking the windows off track. Didn't do that in my explorer. Now that I learned a lot since about 10 years ago, I'm assuming his truck peaked a whole lot lower than mine
Obviously the suv is going to have lower db. The subs have more airspace to fill.
Random Tube the SUV achieved the loudest score between the 2 vehicles, at a different frequency.
www.GPcarAudio.com Im a bit confused.
Random Tube you are very confused ... you need help
KINGKJ2REAL Only the way it was explained in the video. Maybe not enough details. Kinda through me off.
Boa noite sou do Brasil e queria saber um programa para eu colocar no meu Notebook que ele reconhecesse o SPL
Good info but slightly misleading.
Not disagreeing, but how it's this misleading?
Im glad you replied lol .. its not I likely made this comment with out actually reading everything first.. or I was slightly inebriated it happens from time to time.
So was I. Lol. I didn't know what you were talking about.
love your guys products but still can't understand why you are using 6.5 subwoofers! uhhhh so small!!!
Johnny DiTommaso lol yea man this is just a fun little project we mess around with, wait till you see what happens to that eacalade 💪
It's always gonna be louder in a truck
Everybody knows suv hit harder
What are the main difference if you put it in a small car? Lets say a Honda hatchback.
You'd want a different enclosure, a lot of success in the crx for example, subs forward ports back
www.GPcarAudio.com when building a flat wall burping box, do you usually build it with the box volume each sub needs or you go higher?
In a ported enclosure, It depends on the driver and how much power you have. Typically you can manipulate larger gains by going larger on the enclosure, you just have to be sure your port velocity is dialed in correctly.. The larger you go the more "peaky" the enclosure will be, but if your're just going for numbers, thats not an issue, just have to be careful what you play and learn the playable range of frequencies.
All these makes no god damn sense to me. Just tell me what I need to bump to lil Wayne damn it.
What I concluded is that these 2 cars are hard to get them loud.😖
Not necessarily, remember we are tuned very low for 6.5"s so we have a lot going against us here. A sub up port back box tuned up around 45 hz in that escalade would do some crazy numbers.
www.GPcarAudio.com Why subs up port back is better?
in the tahoe's/ denali's/ and escalades, cargo area builds under the window line subs up port back has always yielded the easiest numbers. It has to do with how everything loads in the cargo area.
Subs up port back. Thank you. Needed that information for my build
