Can't wait for the end result. Thanks for the great tips also🔥👍

Wow been waiting for a while to hear it!!! Cooool can’t wait to see it finished 👌

Running the wire through that pipe is genius

This stuff never gets old 🤙

Nice 👍🏼 all that hard work is starting to paying off .....Bass!

Yes and Sir. Its getting real

Watching on a smartphone which doesn't care to play frequencies below 160Hz... I couldn't hear it! And when you spoke I couldn't hear you! That tone masked all sounds and effectively muted you! LOL! I believe in Project SPL! Great work! Stay motivated.

Man awesome hope I get a chance to hear it that thing is going to bang 🎶🔊on 🔥👍

Moving right along

Well done bru! She's alive!!! Xx

Lol your face on those dustcaps is truly humorous... so fucking funny!!!!!

Hell yea bro! Been waiting for this!

I salute to you Derrick! Great SPL working on the go. An annihilating Low Frequency sound coming. I'm sure it's gonna be a SUB ANNIHILLATION literally.

Derek..all i got to say is i hope everyone is bringing there a game to these shows this year..cause i feel you just built a beast..i bet you almost cryed when youherd that first note..a long awaited road..been watching every episode..cant wait to see it fully complete..congrats bro.

Great work, very inspiring, anything is possible, I'll be posted waiting to see this thing in the lanes, going to get STUPID loud, 😎🤜🤛😎

Sweet bass action brother sounds great 🔈🔉🔊🇺🇸#Merica

I've heard of "bass in your face" but this is the first seeing it the other way around. nice mug shot!

Bro I am not really into audio like this I have a single 8" in my car but hats off to you for this series I've watched this whole series love it 😍 I need to pick up an sa8 for my car and a 1.5k amp for it

I can tell by the smile on your face when you stuck your head in the Box that you know it is going to be loud :)

Oh hell yeah!!!

Been watching this. Some great ideas here. Especially because I have an 03 2 door blazer that's gonna meet the same fate. Just stashing equipment right now.

Awesome Derrick! Almost there man. It completely drowned your voice out when the bass was playing! Hard to tell what it's doing with one amp. What do you think it's doing SPL wise with one amp? Thanks for the tip on using pipe. I think I will definitely use that tip on our massive demo build. Will definitely come in handy. Tuned in for the next update!

Dope

Shouldve thought of that when i did my box smh that tube trick is a new one

O hell yess 💪💪

Great job tho bro 👊

Making me want to get 2nd amp and strap em. Won't be nothing on this but should break 50 at 28hz on 2 15s in a bravada

God please don't take this wrong but you said to not skimp and to make sure all connections are perfect so this is what I would do. This would add maybe $40 to the build. I would use wire ferrules and marine grade heat shrink to hold the ferrules in place. This makes sure all strands are being used and making the same contact patch. Then, nut inserts for mounting the subs. Pre drill and insert the nut insert. Then you can remove the sub 100 times without damaging the wood. They make deep ones if you're worried about anything. Plus machine screws can be used. They have more threads and are stronger. These 2 things will make life easier if you have to replace a sub. You can take a sub out. Put the screws back in without stripping out the wood. And then you can just pull the wire ferrule out and push it right in the new sub terminal....not having to worry about twisting the wire or strands sticking out. Chances are you WILL blow a sub. Just wanted to suggest. Love this build bro! You're old school and I love it!

Those are horrible ideas and wouldn't work well in this build. The fact you even mentioned them tells me you can't have much experience with those products. I like wire ferrules and use them for some things but they would suck for this. Same with the inserts.

@@UnofficialAudio and I figured it would be negative but I didn't honestly think it would start out with the words horrible ideas and then and then going to make me feel like a complete idiot when obviously I spent a lot of time thinking about how to phrase this in a way that I didn't seem like I was trying to correct you or be condescending. You literally sounded like what everyone hates to get in the comment section. I guess even if it was not the best idea I would never talk to someone like that that had tried to help but then again I would have been more thoughtful especially being the representative of a product line. I run Sundown products in several of my builds and enclosures right now and have recommended them numerous times but not anymore if this is how genuine suggestions and help are met from the company itself. I could not imagine Rockford Fosgate or Alpine or even another small company would have responded this way especially when my first words were already on the defensive by stating God please don't take this the wrong way. I was hoping my instincts would be wrong. How in the world could what I have suggested been horrible? Maybe I just have a ways to go before I know everything. Sorry that I took away from your valuable time to have to read it...

@@UnofficialAudio The procesess I described are literally used by so many installers everyday. I guess I could understand if one didn't have the time or care to do these simple things. You're going to tell me that other SPL competition vehicles use wood screws, sorry decking screws, and bare wire has the best process for installing subwoofers in an SPL based system? I mean I even liked and subscribed to this build. Not in a million years that I think you would talk to anyone like this.

16:26 is just halarious to me!

Hey them 7500 is a beast. My crecendo will do .5 but it dont like it at all.

Same thing happened to me I watch the video because I will not be able to sleep lol I thought you will meter it😊 👍✌👋👊

Love what your doing I just got my first sundown speakers off a buddy I've always wanted some for years it's a pair of sa 15s there in the back seat of my truck and there loud I love them how can I tell what rev they are

Sounded like when you touch a guitar cable to your tongue 😂. Great work man!

Lol "this is my happy face"

Tiny if: You could have used a counter sink bit on each end of the speaker wire pipes pass through's, that way the speaker wire wouldn't be rubbing a 90' knife edge ;)

Boom

Damn😁😁👍👍

That enclosure style is the same as the old mtx van used. I noticed it In kyles (clippos) video of the mtx van resurrection so you should get pretty damn loud.

What is the significance of the tubes inside the box? Idk why but I really like it. Obviously, I'm not an aficionado. I used to make bass tubes for speakers of all sizes as a kid but I've never seen a build like this before. I really wanna know how much it helps. I'm currently in design mode for my 2 door Blazer, looking for ideas. My benchmark is The Alphard Blazer.

I'm baffled by this entire build myself. I've always been a simple system guy, since I lease my vehicles. But I watch a lot of these build outs, and this is the first one I've seen like this. I mean the subs look sub par (except for the face on them), compared to what I was expecting since, you know... Sundown. 4 unported enclosures, mounted in a massive box? Resonating chamber? I feel like I'm having Higgs-Boson episode or something.

What’s the sealed displacement for the tubes per sub?

Damn I just got hype as fuck. We got sound. ...... can u hear me now

that sub box is good for bove 100HZ lol

love the build .. im gonna be starting my rebuild with 4 zv3 15s .. Mite do a 4th order bandpass this time But never had one before and don't wanna be disappointed. What are your thoughts over ported wall and bandpass 4th order .. Did you ever switch from one to the other with the same equipment And if so what was the difference.

I have 2 sa-10 I want to upgrade to the u series 10 inch. Can I just swapped them and use the same encloser that I'm using for the sa10. I know the u series are longer in depth. Thank you

How would a enclosure like this, once finished, actually sound with regular music?

Why sealed vs ported? Looks great, keep up the great work. Much appreciated.

Hey Deric, couple of questions. Back in the days we used to have stereos that had lows you could hear for blocks, now not so much. My question is, did the speaker designs/specs change? I remember in the 90s boxes needed to be made huge 2 cu.ft. or more for some of the more powerful speakers of the days. Now boxes are small as hell. My question was spurred by the size tubes you used to mount the subs in your bandpass box. I'm enjoying watching the build of project spl! Oh my first projection helped build (because I was in woodshop and had the tools to do the work) was stuffing 4-12 inch atomic subwoofers (long since gone) in a yugo for a stereo competition in 1991. He didnt win but he broke the windshield. Lol. So that's why I wonder how so many boxes are built small. I remember spec sheets saying how big the box should be. Does that happen anymore. Have not bot subs in about 10 years. Would love to get a set of SA subs one day.keep up the cool videos sorry if this was all over the place.

I noticed the same thing back in the 90's, bass could be heard blocks away with only a few subs. I bought a 2,000 watt rms sub recently and can only hear it in the car, sound doesn't carry much past the vehicle.

what amp are you using??

Let’s hear it on music next
