So as you know, going to a lower ohm load, your THD raises. So I would try a higher frequency. Also, if your just going for SPL, open your LP filter all the way or run the amp in full range. Also, put a oscilloscope on your head unit on the frequency your running to see where it clips at so you know not to run the volume past that. Distortion will give you a lower SPL reading.
@Shane DriftKing M3 Turner yeah... 144 is not that loud. I consider something to be "loud" when it reaches the 150 mark. 150db is a respectable number and 160+ is when you know someone's system is serious
@@djshedd77 144 is very loud compared to 99% of the nutsacks out there that think they are loud. Though they have systems that do Mid/High 130's with the factory door speakers playing with 10% distortion. Side note I do agree that LOUD starts with a "hair trick". Real close to 150db
Man I love this channel. Crazy how much money I wasted in the early 90's buying junk before saving up to buy a Fosgate Power 300 and Punch subs. It was worth its weight in gold but also cost about it's weight in gold back in the day. Keep up the good work!
more power consumption due to clipping? clipping by definition means your out of power. So no soup boi not at all. Once a systems max output is reached just to gain an extra 3dB requires twice the power. Still hasnt explained the lose but heat and inefficiency would. An efficiant amp turns 100% of the power in to power output. Impossible. Cheap amps ran at around 80-90% efficiency. The higher wattage just translates into heat clipping and disstorion in the output signal. The magical at 1%distortion rating is used for a reason. Every amp is capable of exceeding power output above it but the output degrades rapidly.
If you were my neighbor, I would show up with Pizza, soda, beer ... everytime I heard you experimenting with gear. I got into car audio as a teenager in the late 70s. I remember Blaupunk as that German brand that came as OEM in Porsche and a few other high end German cars. Never would have thought that name would be associated with dirt cheap gear in the future
Nice test! I was predicting around the 140db range and you nailed it :) I bet if you played with the port sizes some you might find a better tuning to squeeze out another db or 2...or build a beastly 4th/6th order for even more...Cheers!
Wired at 1ohm, set the volume on high, pause the track, power the amp up, and then just burp it. If you actually get that 950w for 1/2 second of full output, you should be good. Back in the day guys used to run their A/C on high forever to get the amps cold too. I think that was mostly superstition, but a bag of ice would be fun to try. All you need is that 1/2 second...
I tried this and it didn't work. I think the amp goes into protect before the meter measures. I'm going to get a TermLab to try as I've been putting off getting one for a long time now....and it's time to step up my game
The problem with that is when you wire below stable load, the protection circuitry goes into effect when the rail capacity exceeds a certain limit. This is why “burp guys” typically do a “slow roll up” so that the ohm load can safely increase to a limit the amplifier will allow
Yeah and you're right people sitting there running your AC that's not going to do nothing but draw current and pull power away from your system because unless he's got the amp mounted on the dash lol those AC vents are not going to do nothing later bro
@@robertpinger2537 very intellagent comment. 100% correct . When we burp at .25 ohm Some times our rolls take 20 seconds to give impedance time to rise.

Been at this since 88, 2 Things you can do to improve SPL with that box and in that type of vehicle. 1). Port it properly. You will EASILY pick up 3db just by porting/tuning that box properly. Those are port caps, they are meant to have an ABS or cardboard tube slipped over them which is trimmed to the correct length to make a port, they by themselves are not really supposed to be ports. I'm going to guess by looking... that the ports you'll eventually need will be close to 5 - 5.5 inches long. 2). Stand the box up, move it as far toward the front of the vehicle as you can, and point it to the rear with the ports at the top. The angle of the rear window will reflect the sound down into the hatch area where (as you know every time a low frequency sound wave bounces it matures) you will benefit more fully from "cabin gain" than if you put the port on the bottom and significantly more than if you faced the box forward. I expect you could be seeing 144 - 146db pretty easily. I'll lend you an HCCA 2100 for $50 lol!
I modeled these Blaupunkt's and guessed at his box dimensions and port size based on the data in the video his port air speed at full watts with these drivers are crazy high (off the chart high).. these subs are not reccommanded ported.. the only way to port them and get acceptable results are much much larger ports to prevent breakdown of the tune with the port airspeed..
He's already peaking in a nice, high freq to get decent numbers out of those. Shorter port designs tend to peak way better for spl, so, his ports are pretty good, really. Personally, I would have done 1 common chamber, one larger port about that same length. But, this looks like an obvious old school box from the 90s when we often did double ports per chamber.
So as you know, going to a lower ohm load, your THD raises. So I would try a higher frequency. Also, if your just going for SPL, open your LP filter all the way. Also, put a oscilloscope on your head unit on the frequency your running to see where it clips at so you know not to run the volume past that. Distortion will give you a lower SPL reading.
It goes to show that you don't have to sell a kidney to get some bass! I'm thinking about putting two of those in my 2005 dodge ram quad cab! It helps when you are trying to talk the wife into letting you do something like this that the cost isn't so much! Thank you so much for doing this! Great channel man!
Less db probably a result of mismatched refresh intervals in the equipment. If the AMM1 is refreshing every 100ms but the dbMeter is refreshing ever 500ms you get weird results.
@@johnhornbeak5735 They're talking about the how often the test equipment measures, not anything to do with the amplifier. Basically the refresh on the sound meter was slower than the refresh on the power meter. That is why it only showed 137db on 900 watts, if Big D would have let it play a second longer the meter would have probably read higher DB.
Your measuring spl so the smaller the cabin the higher the pressure. Try raising the box up on a platform or making a temporary wall with some paneling. This will reduce the air space of the cabin.
@@keaton_mcrae powerbass 10" 275w sub and stetsom 1600w amp wired at 4 ohms, did over 145 on 95$ using a 400.2 powerbass amplifier too, my ports are made by baby milk cans btw lol

Clipping, once you go to high your speakers don't understand a square sine wave... It does more to hold at a point than move the speaker to a nice curve
My God I keep seeing people ask this. Do you really think it's an app from the App Store? No it's an app from the App Store that connects to the $400 sensor that's inside the car it's not a freaking Standalone app

Great vid Big D, the dB score was less because the amp went into protect before the cabin could pressurize enough and your meter responds a bit slow. The cabin of that Sequoia is massive and takes longer to build pressure up front compared to a small hatchback.
Even better would have been a comparison "taste test" style... Person picks their favourite. A $150 budget build and custom box vs. a $1000 big box retail store setup with subs amp and enclosure.
@@zachjohnson1 did I say had to be his? Or that it couldn't be demo equipment? Or that it couldn't be that of an acquaintance? Relax...was just an idea. If I am deemed responsible for Big D's financial insolvency I promise I will assist.
You could of discarded the amp In this budget test. Keep in mind you are using 60hz as your test tone. Simply run an extension cord to your vehicle and connect it directly to your speaker terminals. Again, just because you have high wattage it does not mean you will get high SPL. It has everything to do with the speakers linear Xmax, after the speaker reaches its xmax limit it will distort and change tone so the SPL from your tuned cavity suffers. Regardless its fun to see. Have fun and keep those videos coming.
Very impressive... you just proved my point... Damn less than 150$ Guess it really doesn’t take much... I’m seriously re thinkin my entire build for my 3rd vehicle 🚗 🚙 🚘
Please don't roast me but, I had a situation where my garage sub, powered by a Dayton Audio 500 plate sub amp, disintegrated (origanal J B L) a pinch with another garage party looming, I bought a Lanzar 12in as just a plug-in for a temporary cheap solution. A year-and-a-half later it's still in that enclosure and it sounds f****** fantastic still. More importantly, it has earned my trust. This from a guy that was a JL Audio snob.
Great video and great attitude. Looking forward to see if you cant get a burp out of that 1 ohm setup! This reminds me, I've had an old skool mega-low ohm stable amp I've been meaning to hook up as many cheap subs as I can find.... this has just made it seem like less of a daft idea :D
Either subs are on their way out or distortion killed the SPL.great box.really shows people that it's all in the box.well mostly.cant believe it broke 140 on those subs.fun video bro
9:04 The power compression of the drivers probably takes effect. The amp is clipping, which causes the avg signal to increase from sine (crest 1.414) to square (crest 1). Accordingly, the coils of the drivers become very warm, the impedance increases and the efficiency decreases further. This also happens on the amp side, where the power supply outputs less on the output side as the switching power supply collapses. This then draws more current, but loses efficiency.
Man that is awesome numbers for that setup. Since your box is an “experienced” setup for some ol’school rockfords. Maybe try a different box fab. I bet these subs would put out some bigger SPL in a properly ported box enclosure? Just trying to help. Love your work!
I just got back from an unofficial soundoff in Odin Illinois that had a friend of mine that picked up 4 of these. He managed 149db in the kick panel with about 5000w available to the subs. I was shocked at how well they did.
Thanks for the video. Were you using just straight 60Db? Or what was the frequency cut off? I'm sure you paid a good penny for that meter. But if you could secure it so as the speakers are pumping you could also show in reference to how many watts are being thrown through it. Watching the video not able to feel the bass. This is just a idea maybe a bobblehead. In my Toyota the rearview mirror really starts bouncing. Something to give the audience the effect. Can't wait for the next video
Might check the glue under the rubber ring on the Blaupunkt 12's. My surrounds were not glued that well and had leaks where they mount to the basket. I bought some around the same time you did Big D before the price increase. Audible noise was present in sealed boxes until I added a little glue.
Nice video and the box looks good , you've got a setup that I have been thinking of woth 4 10s . Faced up exactly like you have , I noticed your ports are facing up rather than to the side or back . Is there a reason you did it that way and what differences would there be vs placing it on the side vs straight up . Also what is your port velocity woth those multiple ports . Just curious

Less db probably a result of mismatched refresh intervals in the equipment. If the AMM1 is refreshing every 100ms but the dbMeter is refreshing ever 500ms you get weird results.
That's what i was thinking to, latency actually or mismatched latency might be the cause
This is the correct answer.
Is there a standard refresh rate of most class D ? Or is it a factor of the quality of the power supply (Example: JL vs cheap SSL amps??
@@johnhornbeak5735 They're talking about the how often the test equipment measures, not anything to do with the amplifier. Basically the refresh on the sound meter was slower than the refresh on the power meter. That is why it only showed 137db on 900 watts, if Big D would have let it play a second longer the meter would have probably read higher DB.
Why would it be designed that way. I'm slightly confused.

Even better would have been a comparison "taste test" style... Person picks their favourite. A $150 budget build and custom box vs. a $1000 big box retail store setup with subs amp and enclosure.
I see all kinds of possibilities for future challenges 🤙
So you expect Wiz to pay $1k to a shop for a setup just for your viewing pleasure? What exactly would that accomplish?
@@zachjohnson1 did I say had to be his? Or that it couldn't be demo equipment? Or that it couldn't be that of an acquaintance? Relax...was just an idea. If I am deemed responsible for Big D's financial insolvency I promise I will assist.
IF only we could have this back when we were in High School :P
Ssl makes a $30 12 with a fs of 30hz, 90db 1w@1m, 400 watts rms.
Have a link for this? I couldn't find that same price....
They're $70 Canadian for the 12", $32 Canadian for the 8". Cheapest on Amazon.
@@MidnightToker24 amazon is not the site you are looking for
@@toveryonder1115 what IS...?
@@toveryonder1115 for Canada that is the cheapest out of any site that I found with shipping factored in.
blau-punk-t! great vid bud!

I gotta ask Big D, what app you using on your phone for the SPL?
its not an app, he has a meter in the car, but it connects to the phone for a read out. the black box on passenger floor i think is where i saw it
You could of discarded the amp In this budget test. Keep in mind you are using 60hz as your test tone. Simply run an extension cord to your vehicle and connect it directly to your speaker terminals. Again, just because you have high wattage it does not mean you will get high SPL. It has everything to do with the speakers linear Xmax, after the speaker reaches its xmax limit it will distort and change tone so the SPL from your tuned cavity suffers. Regardless its fun to see. Have fun and keep those videos coming.
More than likely the subs were over worked at the higher watt causing distortion at the subs so they didnt work as efficiently?
Thanks for the 9 Volt Battery Trick!!!
I wanted to hear a song...
No laughing here man great video as always!
👈😜👍
Try it with one of the Rockford amps just to establish a real measurement.
Ha! I wanna try all kinds of amps, including the Orion 3k HCCA 👈😜
Cheap audio! Yay!!!! I have two daughters and two sets of braces to buy but I still can swing this!
Yeah boi 🤙
I got a yeah boi!!! I m honor ed!!!
What’s sad is I don’t even have the money for that rn 😂
weirdlife_8 _ 🤣🤣🤣
Me either!!!!
@@tatialo37 same lame
Very very impressive big d.
Love the vid.
Bet at 2ohm that amp would have gone into protect. Rise you would be 4.3ish
I think it would do great at 2 ohms mono. I’ll need to add 4 more woofers though 👈😬
@@wal that or change to 2 ohm subs. Perfect world right..
Very impressive... you just proved my point...
Damn less than 150$
Guess it really doesn’t take much...
I’m seriously re thinkin my entire build for my 3rd vehicle 🚗 🚙 🚘
I was at $132, even more impressive IMO
Distortion or subs maxed out at higher power so lower dB.
The intense music was great for suspense 😂
Gotta feel what the Rock is cooking 😬
OK that amp is more than $150 tho
Fun video, like it.
Thanks man!
Well, now I know what I'm putt in my little 2002 Suzuki swift. Thank you for this video 👍👍
Yeah boi!
How have I never heard of that 9v trick before? Smart.
You can also use AA battery. Subs just won’t jump as much
Nice project keep it coming for the money you can’t beat it
Thanks for watching and commenting!
Please don't roast me but, I had a situation where my garage sub, powered by a Dayton Audio 500 plate sub amp, disintegrated (origanal J B L) a pinch with another garage party looming, I bought a Lanzar 12in as just a plug-in for a temporary cheap solution. A year-and-a-half later it's still in that enclosure and it sounds f****** fantastic still. More importantly, it has earned my trust. This from a guy that was a JL Audio snob.
This was fun!
Thanks for watching and commenting!
OLD SCHOOL!!!!!!! hardly any money and it knocks!!!!!
Great video and great attitude. Looking forward to see if you cant get a burp out of that 1 ohm setup! This reminds me, I've had an old skool mega-low ohm stable amp I've been meaning to hook up as many cheap subs as I can find.... this has just made it seem like less of a daft idea :D
Parts Express has the Titan 10" woofers for $10.78 each. Those would make for a fun project too
Either subs are on their way out or distortion killed the SPL.great box.really shows people that it's all in the box.well mostly.cant believe it broke 140 on those subs.fun video bro
Finally someone who uses hearing protection!
Awesome video! Keep it up D!
Thank you for watching and commenting!
YEAH, Boi..!!!! You BIG Dummy..!!!! My TWO favorite phrases now!
I like the videos outside the lab. Curious to see what they hit rear facing!
Me too!
What a fun idea for a contest.
😬🤙
Awesome video Big D!!! One of your best!👍👍👍
Thanks brother! It was very fun to make!!
9:04 The power compression of the drivers probably takes effect. The amp is clipping, which causes the avg signal to increase from sine (crest 1.414) to square (crest 1). Accordingly, the coils of the drivers become very warm, the impedance increases and the efficiency decreases further.
This also happens on the amp side, where the power supply outputs less on the output side as the switching power supply collapses. This then draws more current, but loses efficiency.
Those subs offer phenomenal value per dollar!
Absolutely!!
Great videos man. Fantastic subject and study. Niche video style, keep em coming. Thanks... I'm not calling you big d ... but really, Thanks.
Man that is awesome numbers for that setup. Since your box is an “experienced” setup for some ol’school rockfords. Maybe try a different box fab. I bet these subs would put out some bigger SPL in a properly ported box enclosure? Just trying to help. Love your work!
now That is bang for the buck!
No doubt!
Impedance matching is why you get less power at 1ohm. The amp is stereo and designed for 4ohm bridged. But its always fun to try pushing the limits!
Yeah, why not? For science 🧪
Come on big d that box cost way more than 150$ ;) great vid as always
Cost doesn’t include box, just subs and amp
Freakin cool video my brother.
Thanks for watching and commenting!
Nice starter set up
Bandpass box's and forth/six order boxes are what big boy do check out exos setup you'll like.
I just got back from an unofficial soundoff in Odin Illinois that had a friend of mine that picked up 4 of these. He managed 149db in the kick panel with about 5000w available to the subs. I was shocked at how well they did.
We got 147.5 in my Ranger in kick with 2850W. Pretty crazy for $80 worth of subz
@@wal Kids have it so easy today. I had to spend a couple weeks of income to get a decent sub when I was in high school.
Thanks for the video. Were you using just straight 60Db? Or what was the frequency cut off? I'm sure you paid a good penny for that meter. But if you could secure it so as the speakers are pumping you could also show in reference to how many watts are being thrown through it. Watching the video not able to feel the bass. This is just a idea maybe a bobblehead. In my Toyota the rearview mirror really starts bouncing. Something to give the audience the effect. Can't wait for the next video
Might check the glue under the rubber ring on the Blaupunkt 12's. My surrounds were not glued that well and had leaks where they mount to the basket. I bought some around the same time you did Big D before the price increase. Audible noise was present in sealed boxes until I added a little glue.
Thanks for the tip!!
Nice video and the box looks good , you've got a setup that I have been thinking of woth 4 10s . Faced up exactly like you have , I noticed your ports are facing up rather than to the side or back . Is there a reason you did it that way and what differences would there be vs placing it on the side vs straight up . Also what is your port velocity woth those multiple ports . Just curious
I learned something. Thanks.
