“Buy the car,cut the car, enjoy the car.” You only live once! Brilliant Pete🤙
Yesssss!!! An hour long! I'm about to grab my popcorn!🤓
It’s 11:10pm I’m laying on my couch 22 minutes in watching a movie on Netflix. My phone lights up with a TH-cam notification. I click on it and I see a one hour long video by Peter. I paused Netflix because I have to see what I’m going to learn from Peter tonight.
And what did you learn? 😀
A lot of reminder’s as to what I already learned from you. But may have been placed in storage bin that I kind of forgot about. Happens when you don’t exercise that everyday. Muscle memory for the brain! I like the speech that is given for the last 10-15 minutes of the video. Also getting little bits of more in-depth information on phase and the cause & effects if its not correct. The more I watch you go over the measurements the better I understand what I am looking at. what i should expect and what adjustments will more then likely have to be made.
It’s a constant review, the more I watch and read the more little details I will pick up that I may not have before. Sometimes you better explain things in your videos that you might have given a briefing on before.
myboy051 i also improve in that respect i guess by time. 🤷🏻♂️😀
@@pssound9749what tyre of materiel you use in this milk shake.
Yeah, I'm watching 3 years after you. It never gets old.
Best car audio channel on TH-cam. Period.
Bassheads would definitely argue with that! 😃
I agree. So good to see someone who takes such pride in their work.
I absolutely do not understand how you only have 12.5 K subscribers. People need to start hitting the Subscribe button because you're getting that many views on one video. Thank you for all the valuable strategies and techniques.
I Totally enjoy your videos, thanks for sharing your knowledge, we appreciate your time ana and effort Peter
One of your best videos yet as allways thanks for the info and keep up the good work.
It’s very impressive, Peter.
You inspire the world with your innovations regularly. Thanks a ton 🙏
I remember a few episodes ago you said you were going to invest in a nail gun to save time and I see you did, cool and good for you Peter 🙂. Fabrication is a beast I mean it just takes so much planning and gaining in experience by watching videos and then just trying your hand at. I remember back in the day screwing amps and distribution blocks to a board and hiding wires was an accomplishment lol but nowadays it is art and creativity. I wish I could go to the mobile solution school just to learn more theory especially about tuning, how stereos connect in modern cars and frequency adjustments to dsp regarding hertz and stuff. What a hobby I used to just want good music now I really want to hear it
Peter I always admire your work.
Love your work and keep up the good work
Excellent video Peter! I am busy installing an 8” Audiofrog subwoofer in the same location in a 1995 Mercedes.
I am blown away by the amazing work you do. You are the master of car audio.
I watch it till the end as always :)
Good job Peter, also as always! I hope we'll see us someday again at the euro finals. Fingers crossed.
I didnt realize until the end of the video what BMW that was, I remember when you did the installation, one of my favorite builds. Gorgeous fab on the a pillars and sil. Awesome work Pete!
I enjoyed watching the video until the end. Thank you so much for the tip about creating a frame for the front baffle to attached to.
Very informative. Thank you for taking the time to explain these important details.
Bonding frame with large cut out before scouring front baffle is fantastic tip
Siempre brillante Pssound 🎉🎉
sealed off a trunk on my 68 Chevy nova for an IB 15" setup..
Day 1: Started up with a fresh board of plywood
day 42; icecream sticks with a glue gun in my self created 4d puzzle of doom.
day 50: It would have been faster to seal the holes from the inside out instead of outside in..
day 1.2 : Yay, plywood, silicone.
day 2.2 ; Awesome sound :)
From failure comes progress and knowledge.
Just watched this for the second time and I love how you did this setup. This is exactly what I want for my series 3xj6. My carpet isn't as thick so I'll have to do a lot of planning on what space is available so I can decide on the driver but getting tips from all your vids im confident I'll get it worked out.
Good luck with your project! 🤘
You are number 1 for me Thank you for all the advice
That's why you're my inspiration!
Well, that explains why it always sounds better with the windows open on a nice sunny day.
The gain achieved from simply opening windows is a good example of the difficulties installers face getting good, reliable sound in a vehicle.
And yes I watched the entire video as I always do with Peter's videos.
Very good content ! very detailed video ! Thank you ( love when people help other to understand the process that nobody wanna speak of )
awesome work
I'm at the part of the video and I'm going to guess around 10 liters. I recently built footwell enclosures similar size for Anarchy midbass drivers. I used the puzzle technique I learned from you. I love your attention to detail.
What kind of car did you make the kicks for?
Thanks for these videos. It’s nice to watch and learn how professionals do and at the same time also find new ideas and implementations for my own sound quality building project.
And the videos are never too long they just have to be watched in several parts so nothing goes unnoticed.
Keep doing what you do..
Watched again a year later. Nothing wrong with taking a class twice. 👍
Ounce again Peter awesome job!
As great as you are at enclosure building it amazes me with the honda you built IB instead your favorite sealed speaker size even though it is awesome work
E. Davis 18”s in true IB is a whole different world! 😃
Love the long video, great work as always
Peter whats up bud,always love the videos as always
is there anyone else on youtube doing the level of the work of this man. always top notch. i wonder if you rip out the center shift area is there room in there. i have a jeep i may have to have a look.
i cant wait till the weather warms up. i have some work to do. always an inspiration.
MRgreen you can’t rip that in this one and i doubt you’d have any space.
Wow, fantastic video informative & step by step approach to achieve sq goals.
Watched the whole video over lunch. Still to cold to work on my car 😞😞.
Order coming soon Peter.. Keep it up 🔊 🔊 🎶🎵.
What did I learn, will be using spade connectors. Take my time to build my system... installation is key..
Jeff3 yepp, this weather currently doesn’t help, it’s bloody cold in my garage too! 😀
Great video again
Amazing the front imagining Must be mesmorinig. A concert on the dashboard!
That’s always the goal and this was ticking all the boxes too! 🤘🔊🔊
"Theres not a single soldering in your car" pretty sure all of the PCBs in your car doesn't agree :D
But great video, learning alot from following you :)
Haha, that is a board, not a link connection. 😃
Great job ✊😎
Actually this video make me think about my own, I have a truck single cab , have a lot of space behind the seats but was thinking to set the subwoofer in the front at passenger side, to leave the back space empty for tools. Actually my subwoofer is a Ultimo titanium SC 104, that as per manufacture needs a minimum of 13 liters up to 30, Thanks Peter, The question is still I need to have a sub behind the seats?
Cruz Morales location vs cabin size, that’s what dictates! Unfortunately i haven’t worked on many pick up style cabins, they are not popular in UK.
Super helpful video. Sub'd for fantastic information. I am doing a Focal 10" up front and am wondering about that bottom octave. Will have to consider options.
Peter, if you weight the enclosure before and after filling with water you will have the exact volume easily…just think of that after look again at your video. Maybe it will help 😉
I don’t have a big enough scale, sorry! 😃
@@pssound9749 😅 stole the one at home 🤣
@@ulrickteissier363 hahahaha we may try it 😃
All of it 👍
Amazing content!
Hi! I'm trying to decide the optimal location for a front subwoofer. Would you recommend placing it in the passenger footwell or the glovebox area?
You're not kidding about the effects of contorting yourself into footwells, just running cable or doing any work under a dash for a few minutes can be a terrible experience.
Morel Ultimo Titanium 102/104 have 600W RMS and Frequency response of 10-900Hz and similar sensitivity of 85dB only con is that it's almost 1.5" longer than 10 WM. Morel paired with Helix M One X (having Freq. res. of 10-250Hz) would have been able to produce the low end bass (20-25Hz) as the rear sub?
I looked at the specs of some subwoofers where it was mentioned ported sub box makes lower freqs. than sealed boxes but need more vol. Do you think a ported box in the front would make a difference?
The Focal TBM can go to 50khz according to it's spec sheet, is that even noticeable coz usually tweeters are up to 20khz or 25Khz?
Love your work on this beamer, would have loved to see some glimpses of your tuning session. 28:27 I would have added a layer of chopped fiberglass from behind the plywood and in front also before applying Resin and make a sandwich between 2 plywood layer. This way the fiberglass layer is also a part of the plywood and is not just held by the resin alone.
Was the front sub bolted to any area of the floor or firewall? I’m asking because if the enclosure can be mounted solidly it will give more solid impacts of bass. I bolted a fiberglass sub enclosure using auto sub box carpet I soaked with resin. I braced the inside with 4 3/4” mdf stands about 3” wide from the inside from deck to bottom. I made to hold 4 12” JL 12W3 subs into the spare tire wheel well into the trunk of a 93 Acura Integra gs-r with 500 watts rms by 2 Precision Power PC21400 amps. Had to run a custom wound 300 amp alternator.
I watched all of it my friend i love it and i learnt how to fabricate for ftont sup ina a way but i have other thoughts of location in play lol idc about anything in the vehicle really lol i plan on making everyything sub boxes xD but i just right now i have a 03 lancer its not big i do have 9 rockford subs to go in tho lol XD. I have four in place of the back seat with a peavy 12inch cab i opened/gutted then made into a ported box 4 4 10 inch p3s :)
Great work as always .... just wonder how come you don't do port for it or any of your kick build .....???
Group delay
As above, group delay is one of the reasons. Also, ported enclosures needs more volume and most cars don’t have that luxury.
Class is in session!!!!
Good day Peter. Brilliant installation as per usual. One thing though would subwoofers in the doors be just as effective or better?
In doors where everything rattles? Quite a tough job! These cars don’t even have door location for larger drivers, just 4” mids. You’d need to build door enclosures like i did in my Honda. 💪🔊🔊
Thanks for the reply.
Thanks for the reply.
I cut my a7 carpet today 😂 now watching this video until fiber glass is set 😂
Great vdo as always, just a quick qns - any specific reasons for not choosing the usual wood process to fabricate the front sub box as a whole unit. Was it because of tight space and contours.
Mr. R.S indeed, in those cases thinner FG mould can give you a bit more volume.
I usually test my fiberglass density by standing on it. If it holds up and doesn't creak with my 230lbs (100ish Kg?) it's probably safe.
Ha ha good one
JayinMI yepp, that test always works! 😀
They cant be to long Peter👌🏽
Your girlfriend in high heels: “Oops, what did I just put my heel through?”
Could you please let me know the dimensions of your 5 1/4 sub boxes underneath your driver and passenger seats that are ported? Also the size of the ports? I have some MB Quart Reference 5 1/4” I was thinking of putting under the seats after seeing your cool install, instead of installing mid bass speakers in the doors. If you could give me a rough idea, that would be awesome, especially the port size, as I can look up the volume size Vas or Q for a box for the speakers. I really envy your installs dude. Aloha, Matt on Maui 🌺
Hi Matt,
I’m a bit confused by 5.25” drivers you’re asking about as this BMW has 8” drivers fitted under the seats.
Ein Traum .
Hi Peter, another great video! Question for you: I've done a similar approach for my car, but uncertain as to the best strategy for time alignment between the front midbass speakers, front sub, and rear sub. Do you feel that the Helix software (I have a Helix Ultra DSP) does good job with automatic time alignment? Or do you think I'd be better off just measuring distances from each of the speakers to the driver's headrest?
I have my well practiced method, that has worked for years, so I haven’t used Helix’s feature yet. I may try it for comparison one day. 😃
@@pssound9749 Thanks. I'd love to hear your take on the Helix feature some time, and if it's worthwhile for those who don't have access to someone such as yourself.
Interesting 🤔 subscribed
if you removed all the air out of the enclosure and filled it with sulfur hexafluoride would the driver play deeper bass. the question seems silly but i dont really know how the speaker works scientifically
No flex test, sir?
Obviously not. What would that be good for?
Hi Peter, how long does it take for you from start to finish to build a fiberglass enclosure for a sub in passanger feet location? I am thinking to build one, since i can't block my trunk and have only front speakers, don't think will add rear fill soon enough. I would like to know what i'm getting into. Of course i will add some extra time margin being the first time i'll do this
Thanks
Hi,
A front sub box is usually 30-40hours work, so it’s very labour intensive, but you can certainly do it in stages.
@@pssound9749 thanks..so, around 7-10 days working in stages after work. Good to know 👍thank you
How many watts did you decide to give the 10WM? In an ideal world would you have used a larger enclosure? I have a 10wm in 0.55 cu. ft. of my spare tire well, fiberglassed in.
We run it upfront, so it can never play as low as from a trunk, so it needs a rear sub for the low lows.
What it does upfront when it comes to punch and playful upperbass is a different story and it’s really not about how much power you have behind it. Give it as much clean power AND stable power supply in the car and it’s all good. Worry rather about how it’s tuned and integrated to the rest of the system.
@@pssound9749gorgeous work peter with the focal utopia m bmw build. did you ever hear about the focal fse 20 flax evo 8 inch shallow sub?. I think that would be a interesting install/project for you in the future, for upfront bass. I think they would do great in a front false floor build, plus you would be able to put them on both sides of the car, right front, left front sides.
I have dual focal 5km for front sub rear 1 jl audio w6v3 sealed box my is car is Toyota cross space issue fronts sub is ok or should I change it
Hi.. Peter way not MDF I think all your installation your using Plywood can you pls explain the benefits of it.
Stronger and lighter
Saludos 👌👌🇲🇽🇲🇽
thanks for another great video peter! i'm hoping you can shed some light on an idea i have. in my jeep grand cherokee there are significant spaces under both front seats. the driver's side is empty and currently houses my dsp. the passenger side has the battery. i was considering putting a small sub, 8 or 10, under at least the driver's seat. initial thoughts?
brett leasure any sub is better than no sub, but you can get better low-end response from a single if it’s on passenger side.
@@pssound9749 thanks for the reply. i should let you know that these would be more like supplemental midbass/subs where i'd likely still have a 15 or something in the rear. i built kicks with 10's in them, but they're starving for air, etc. they imaged well, but they struggled to get me anything in the 60-100 hz range. i was hoping that relocating the battery would be alot easier than cutting a bunch of metal in my kick panel areas.
@@pssound9749 I do believe i heard you say that you would have liked to have the sub facing towards the fire wall ?
If true , In your experience or knowledge do you feel it gives a better response to have it facing the fire wall. Also do you feel a center console sub that’s placed forward slightly underneath the dash would benefit more rather then on the passenger side fire wall area ? Like in the position where you would usually find the shifter but say maybe 6-8” more forward. I ask because I have a Chevy Silverado and it has lots of room in that area. I’ve seen some online put a 10” in that spot with a .6cf sealed box. Don’t know if the work would be be worth it. Oh the sub would be down firing at the floor.
If you had installed the true IB midbass 8" Utopia's first, would you still have done this front sub?
Yes. This car is very long and the sub from the back doesn’t have a great transfer function for upper bass, what the front sub does with ease.
Are the factory 6.5 door speakers in a Honda Odyssey considered mid-range speakers?
I guess a 6.5” would be called midbass.
what type of plywood do you use? is it important?
It doesn’t, it just gives structure. We use birch ply.
thank you! started my build today, following this guide. When you do the first layer of fiberglass cloth in the vehicle, is there any trick to applying the resin upside down onto the inverted piece? I was planning to use paintbrushes but I’m not sure that would work
@@chef_yt that’s always the shit part. It helps if you wet the chopped matter with resin a bit in advance, then stick it up or if you can, just build it from wood on the top.
there’s not a great way for me to build it with wood on the top, wouldn’t be any easier from what I can tell. I’ll try using a strong adhesive tape for masking, supergluing that section of the cloth to the masking tape, and just ripping the tape out with the cloth when it comes out, and sanding off the tape. Probably decreases the integrity of the mat, but I’ll do other layers anyway. Thank you for the help, and great video!
change in plans. masked with blue painter’s tape and carpet protector (cling wrap) and a healthy serving of johnson’s wax. I removed the glove box so I’m thinking I’ll affix coat hangers in the glove box area, bend them down into the fiberglass area, and have the coat hangers holding up a piece of wood shim stock on the front/top of the box to hold up the cloth. I give it a low probability of working, but worst case I’ll cut out any droopy bits and either glass those couple inches with a loose clearance, or put wood there. have you ever had an insufficient mask/insufficient release agent and had to remove a fiberglass part stuck to the frame?
I need more content 😁
Then check out www.patreon.com/pssound 👍🔊🔊
@@pssound9749 I am there already 😁 stayed late last night watching some of the videos. Trying to catch up to your content 😌
@Pssound would a 3d scanner, with a 3d printer work for a box, in a location such as this one?
You can do crazy things with today’s technology, so i’m sure it’s possible, but i’m not sure it’s worth it. Printing a rigid enclosure for a 10” sub is quite a challenge! 🤘🔊
@@pssound9749 it would be great for making the basic shape so you could fiberglass it outside of the car. Another benefit is that the whole deal can be shared as 3d file to other builders with same car and done again.
matsku1212 but the reality of people cutting the carpet....
Who was the closest with the capacity of the box peter
Mark Jackson Lucas with 15.5L.
He already got his prize! 😀
I am asking myself; would a multiple capable 6,5 or 8 inch was used, could that be a solution instead of a single woofer?
Large drivers always play lower frequency range more effortlessly with less distortion than multiple small drivers.
@@pssound9749 I agree Pete, but considering the bandwidth were the biggest problems were, between 50-80 ish was the reason. Right bandwidth of good smaller drivers. But if you want bigger lower output in front it’s logical.
Umıt Bozkır it was also about location related problems with the midbass. If the 8WM was in different location and had no issue in 60-90Hz range, we wouldn’t need a front sub.
Sometimes you need luck with cars and what locations you get.
@@pssound9749 I am going to try with an Aliante 12, and try with multiple 6,5 inches. I have also the same issue with my BMW f11 estate. Depth isn’t an issue with the Aliante, but the diameter of an Aliante 12 is quite large.
Does the water not affect the deadning adhesive?
No. Then what would happen to deadening in a door?
@@pssound9749 i know it can handle slight water exposure i did not know it can do complete immersion in water!
What software is this?
REW.
What is used with the mats? I Don't understand how the case is made.
Is it fiberglass?
Putting the woofer in the doors is the preferred place for optimal output & accuracy and ease of installation in order to have maximum High Fidelity and frequency alignment including sound staging.. .
Not in our world up at our reference level.
I hope you’re not being sarcastic (because many people who follow this channels understand very well how much we hate doors for midbass applications).
@@pssound9749 I build SQ systems and that's enough said.. .
@@bobadingo please share your Fb/Insta profile, so others can learn from you how to use a door correctly.
There are many factors that talk against your view. The doors are uncontrolled and vibrating environments. Also the difference in the distance makes issues compared to kick panels for example. If you do SQ builds, you have a lot to learn. It’s all physics.
@@bobadingo I'm sure you do mr alpha
Yeah,it can be quite painful being a installer!!
would not put one in the front definitely, it was only a matter of time until a carefree passenger stepped on it and damaged it...
What’s a protective grill and the floor mat for?
Dont cut a hole in the foot well of the car youre doing structural damage.
haha the carpet?
Reality is you would probably sell that sub with car as its probably not going to fit in your next one unless you get exact same car I seriously doubt your going to recoup your money on it though. I would imagine most who go to this expense will hold onto vehicle for a very long time .
hope nobody kicks the woofer o.o
You think we left it without a grill and floor mat?
Hi, Peter! Do you have a 10 » woofer with a better budget friendly price option that I can use, without braking the bank with the utopia one 😉. Thanks.
JL has great options. W3 is excellent for SQ too, but if you need something slim, they have many options for that too.
If you have space, then the Helix Q10W is a real jam and is cheap for what it is.
@@pssound9749 Thanks a lot for your quick reply…saw the q10W will certainly go this way but will check space first. Thanks for all that video…i was off of the sq world but i rebuilt a complete setup in my new car…my ap 3c are on the way ;-)
