looks like this woofer still has plenty of excursion left to break in and use. Once the power level and box volume are fine tuned, we'll be able to play this setup even closer to it's maximum limits! Bass songs - test tones, you name it - This install should be able to play ANYTHING once we're done tuning amp settings, adjusting internal cubes, and finding all the weak spots that vibrate in the car. For now, we ran the speaker wire through the port until we can add official terminal cups. So far these Level 6 15 inch subs are VERY IMPRESSIVE sounding. Good job DC Audio! She's slamming much deeper now too :) But why wouldn't it with over a 100 lbs subwoofer, right??? Just about the biggest size before the lower back starts breaking... Bottom line...Crazy hard hitting lows - Great bandwidth with nice and loud peak spl frequency around 40hz tp 45hz... Not sure on the loudest decibel score yet, but it's way deeper than we thought. Overall a huge success and a really fun way to connect with car audio friends :) THANKS FOR WATCHING THIS 15" VENTED BOX PROJECT!

[@Mr.Robert1]

Michael you posted this 5 months ago my question to you is did you build that box and are you satisfied with it if not I have suggestions not by surfing the web but by experience.

[@JamesSmith-br5gb]

The look on his face during that first listen made me smile so hard, would've made helping him build the box completely worth it

[@kjm4ryanna]

It’s so amazing to see the smiles that bass gives a person.

Man I have to give it to you, you’re one of the best when it comes to making boxes and the “how to demo”. I’m going to try & make my first box for two 10” shallow skars for my truck.🚪 A box is what makes all the difference

[@MacNifty]

When you know that bass is hitting hard and you own it and it's yours at any time!! That's the best feeling in the world.

[@adaboy4z]

The look on his face after the Bass!! Love it

[@wwmclawhorn1]

Great video as usual! I wish KZbin and the people would see the time and effort it takes to do a video of this caliber. One of the best edit jobs ive ever seen and im so thankful i got to be a part of it! I am gracious and like someone said in the comments i am super happy!! Thank EXO and the car audio family for supporting such a great guy in EXO!

[@patrickroberts21]

Yo EXO!! I friggin love your vids kid, I just started getting back into audio systems and found your channel. I was a basshead back in the day, but I've been out for like 15+ years and I can't believe how far car audio has come!! Anyway man I was researching trying to figure what's what and who's who these days started watching one of your videos and haven't stopped for like 3 days! Top notch content and information. Keep doin what you do man, I'll be watching for sure, you got new subscriber here.

[@bailey2517]

Seeing how happy he was when first listening to the sub was such a feel-good moment for me. That's the kind of feeling we live for ya know? Those are the moments you'll look back on when you're lying on your deathbed. Makes me happy seeing you both se excited about this!

[@ryandavis4764]

The satisfaction that you gave that guy was AMAZING!! I've honestly learned pretty much everything about box building from you and I hope I can make future customers as happy to hear my boxes jam like yours. Thanks for the new content.

[@MuffinSlayerrHD]

Ryan Davis you got a place where you showcase your work?

[@dougiefresh8234]

Huge box

[@jorgem50]

28:41 I can totally relate to his smile when the bass kicked in. That's how I felt when I put my 20yr Fosgate hx2s in another box and realized how much better they sounded with the new box.

[@jorgem50]

@um me you're so wrong man! Fosgate subs and amps from the 90s and early 2000s are amazing products. Once they started making shit in china is when they went down. But to say they were good only in the 80s...you're so wrong. I belong to a fosgate facebook group and all the gear from the 90s and early 2000s are so highly regarded and sought after.

[@jeroenschuuring6060]

Designed a sub around an e12 v3 for my best friend's son. He was very impressed with the result. So was I by the way. Its nuts what these new woofers are capable off.

[@israelvega344]

What a great job you did with both builds. The first build was the box that came out amazing. The second build is this video that is absolutely awesome, thank you bass head.

[@loko7711]

This is why I have a great respect for you EXO! You have a good time making others feel good about Baaass!💪

[@rollemdoobies12]

I have this setup now. Unfortunately the dc needs a rebuild but I have a zv5 15 in the box now and it absolutely slams! The build quality on this box is top notch!

[@miiiikee_]

Right on! The look on Wesley’s face when the beat was hitting was exactly why we all love some good slamming bass. It makes all the blood, sweat, money, and tears worth it. Trying to get my Tahoe right at the moment, but seeing this helps me keep pushing.

Awesome job, love it when the customer is stoked and surprised at how good it sounds.

[@jman4573]

that feeling you get when you get banging again! i can empathize with this man after i fixed my amp and got to slamming i was one happy camper!!

[@DIYAudioGuy]

Whenever I laminate sheets of plywood together like that I start off by oversizing them at least a quarter of an inch because they drift around during the glue up. After the glue sets I take it back to saw to cut to final size. Glad to see that you do the same.

[@WiKiTWoNKa]

Great Idea

[@Steven-cn8dr]

watching him light up with excitement after he heard it beat at low tones was awesome!

[@changchung]

Bro it is amazing the time that you expend to make the installs, boxes, stuff and editing the videos. THANKS

[@nurk_barry]

Dude, I remember your videos from like 11 years ago back when I was watching Steve Meade vids a lot, you had that sick van setup. Glad to see you’re still doing the bass thing!

[@MaxFiveGames]

Dude... I never like videos, but shit the effort you put in to editing it deserves it man. Great job cant wait for part 2 :)

[@josemontelongo404]

I remember when i used to do this with my friends many years ago. It was a great time in my life and great memories. i wish i had friends like EXO to continue the installs and fun times. Again, a great time when i was young, EXO I wish you the best and hope to hear a system of yours in the future. Im in Chicago if you ever come out let me know. Thanks for always sharing your knowledge.....I have an extensive background in electronics if you ever need help....I Got you!

You are awesome! I nearly spoilt 2 1x2 feet ply boards trying to cut a decent circle - but your technique - is just great - it works like nothing else!

Exo knows his stuff.. I love my car audio if I need to know something I always hear what he has to say.. he explains things like a smart dude would . This box build was helpful for me. Went from the k9, which still thumps but it’s like a sloppy dudd sound of bass if you what I mean just isn’t clean ,but nothing close to the my new level 3s which i love .. I hate Rockville which was a painful lesson I had to unfortunately teach my self.. Thanks exo

[@guhhran8614]

I love to See the happy faces with a new Box. Even a month before i Designed a New Box for a friend. The sub Was quite good but the old Box was just crap. Is Just had some wood and didnt need it so i measured his trunk and build him a New Box tuned at 36 Hz and the difference was impressive and to See him smile over the Sound Just made Me so happy

I've watched your videos for years. Love how you go through everything and always fun to watch! Keep it up man!!

[@ohms5054]

Do you like his steady hands? He gave you a heart too.

[@RagnarokCo]

That's the biggest thing I took away from this video. I've seen him do a bunch of projects and he's become quite the woodworker.

[@AnnaVannieuwenhuyse]

@Chuck Holmes Routers can also very easily get away from the food and fuck you up seriously good. I'd always suggest clamping support braces for your router plane (90 degree clamp blocks)

[@PotatoeChipz]

I finally bought a $26.99 jigsaw and my bro brags about his handheld router. He claims it'll come in handy some day but I question his 20 yr tech professionalism troubleshooting existing network routers.I feel underpaid working as a pimp.

Was there ever a part 2 to this.. would of loved to see the final result.

[@Winters506]

This is why I’m here. I watched part one thinking there was a part two. I have an almost verbatim build so I was curious how they would turn it around and wall it off. I’m interested since EXO said it will sound better and mine are rear facing.
