Good to see it putting in the work like the last prototypes we had put in the final changes to. Thank you again for doing the thorough testing on it. If you want to do a giveaway on it on your channel I’ll refund your money for it 🙂
@THELIFEOFPRICE so much respect for you being such a stand up person. On his first video you offered to send him a free replacement if he blew his amp on .67 or .5 testing, now you offer to refund him if he wants to do a giveaway. I know financially it doesn't hurt you a single bit to give someone $300 but imo its the principle that makes me view you as a very stand up fella. Hoping to see you release a 5k or 6k model of this amp soon. Can't say enough how much I love the bass remote!!
Amazing amp at a unbelievable price. Definitely sold me on your amps and other equipment.
I have 4 of these on the way now. Going to strap them on some incriminator subs. JP, please tell us you have a bigger version in the works too!
@@itdoesntmatterwhatyourname6128 totally agree, he stands by his stuff, and seems like a good guy/company! seen some of his vids also, i think he is a guy i would like in real life, down to earth
WOW GREAT GUY JP!!!
For 3 hundy looks like a good deal, especially with the king of bass knobs.
Finally, a Protect circuit in a modern amp that actually work the way it was designed!
i dunno, mine never worked right and after a 18 months of ownership it let the smoke out. it would overheat FAST... My Kenwood never did... what REALLY pisses me off is the Reviews on Down4South are filtered and my Review was not posted, so do not take what is on D4S at face value.
@@EliteGeeks what was your electrical like? i beat the shit out of my jp23 wired down to .5 and dip it into the "low voltage" all the time and I have no issues
@@rileyh.4554 0/1 gauge OFC, from the battery, 200 amp fuses, all cables are crimped with hydraulic copper end terminals, 3.5f cap 8" off the amp, I put my old Kenwood amp back in, no problems...
1:37 "BRTUAL" ?? :D after noticing the misspelling on the Down4Sound box ;)
lmao i wonder if he did that in purpose?
@@hooptastic_hippie8522 its spelled "on purpose" not in purpose lol you must have had the same special Ed class with JP
I have one word for that... China. 😉
@@MadDragon75 You mean Chyyyynah (as per the White house dictionary 😂🤣)
GOTEEEM!
nothing makes me happier than seeing an amp actually have a very good protection circuit. this means when you're using it and your voice coils tend to go and go up and smoke or start to short you don't have to worry about your aunt going along with it that's a real good piece of mind. Jonathan really has done a phenomenal job with this company and I really am glad that he decided to go ahead and release his own brand of amps
I can atest to this, just had a 3500w 18" sub melt the leads on it with this amp, wired at 0.5 ohm. Amp never went into protect, had it shut off a couple time do to heat. But always reset afterwards and ran fine. This amp is the best.
trash
JP wouldn't put his name on bullshit. Good for him. Nice product
😂
Hmmmm, something tells me that you wouldn't put your name on it.
You get what you pay for and when it dies within a year, you throw it in the trash because it's definitely not worth repairing.
Killer bro hella glad you posted a second video on it. Im at work and literally put my tools down n took my shoes off n clicked play... Hella dope BIG D thanks man.
I purchased one based on a few ideas in my head. 1) JP is a total bass head. He knows what is good. 2) this is the first batch and I believe first batches are usually robust and later versions can be trimmed down in some areas to lower production costs. 3) as this is his first amplifier I figured he wanted it to be a great success and doesn't need a first offering failing and getting bad reviews. Therefore I thought it would be over engineered .
The audio term "how low can you go?!" is present here. Dyno race between all 3 chassis/amps you mentioned would really impress both the industry and consumers who watch your videos. Major props man.
I enjoyed the fact that the beginning of this particularly outlined misspellings and grammatical errors, then turned around and made 1 by misspelling brutal.😊
That’s a big dummy for ya
Protection circuit well designed and worth every single clam. Good job JP. Still wanna see a Sam, Big D and Doug collaboration on an amp from a buildhouse....hey I can dream.
Good protection circuit... same bass knob that I have on my deafbonce aak-4000.1d love thus amp, been running at .5ohm for over a year daily..
Look, I undersrand that having a starting voltage of 15 - 16v gives you cool inflated numbers to look at, the fact is however that nobody is getting more than 14.5 volts from their alternator at full duty cycle, and they're going to see a lot of vdroop from there. If the amp has 12v ratings on the box, try and do your tests so the final test voltage is in the mid 12v, so it's a relevant test for the viewers! Cheers 🍻
Maybe for all the folks with extra alternator(s)? 😇😎😀
I used to get a steady 14.8 factory alt
@@pierrem4153 wow!
Newer cars will vary the duty cycle of the alternator to A prevent premature battery wear and B increase engine efficiency. For example, my Liberty will output 14.4v right after a cold start-up, then quickly fall to 14v no matter the rpm, then continue to fall until the car reads the battery as charged, then it turns the alternator off altogether until a high electrical load is detected, eg headlight, demister, AC electric seats, electric windows all at once.
@@minus3dbintheteens60 good info here I believe my 21 Kia K5 does this
Big D... You're the only person I know that still says "SIKE!"
😁.. That's awesome!
It takes me back to Jr High and High School.
💀 Oops! We're showing our age.
"psych"
@@soniclab-cnc Oh. You know the funny thing is I always knew it meant psych you out, but I honestly never thought about the proper spelling until you just pointed that out. again I haven't said that word since high school & Jr. High.
I guess I didn't learn anything when I was there.😁
Haha - I noticed that too!
@@MadDragon75 I am the grammar Nazi
Why I waited till now to subscribe? I have no excuse. I've been watching your vids for years. I love your honesty, attention to detail, and passion for the car audio industry. Thank you for all the hard work you do.
Also I think the biggest takeaway from your vids and alot of people dont realise is the current draw. I've seen it time and time again. John doe puts a 5k amp on the car and wonder why it doesnt sound like 5k watts. Well, if I can quote Steve Meade, IT TAKES POWER TO MAKE POWER!. You cant have a 5k watt amp on factory wiring and alternator. Maybe with enough caps and batteries, but with a stock alternator, it wont last long...
I enjoy dynamic ratings cause it gives me an idea of how that amp would do on music so F anyone who doesn't want to see
Amen Erik!
No it really doesn't
@@Wesspinna what...
@@Wesspinna yep, it does
That spells some serious quality in being that the amp is severely underrated, but to be honest, for the first time in a long time it is happening again! JP definitely is a good thing for the bass audio community!
😂 really, telling the amp was designed in the us wen its not. thats telling lies to sell more amps
LOL......Serious "quality"?
Are you seriously deranged.
Add the cab 22 into the chat
From now on.. this amps called the JP-ENOY23
"PENOY" means (boiled duck eggs) in the Philippines.
sounds good. the ENOY line.
I took the extreme to a whole other level today. I did extensive testing using a termlab (less clamping) on the JP23 at .25 ohm strapped. That's two JP23's on two Sundown Audio 4 Ohm U-18's. Best score was...ha! No spoilers.
Hope it's okay to say here, I have video highlights of testing coming very soon.
You are the man Big D! Say hi to CCA-Vega for me :P Q'Plah!
Crazy how the dynamic run sent it into protect ! Usually it’s the certified or uncertified run !
‘BRTUAL’....overlooked that one yourself lol.
You big dummy
Thanks Big D, I really appreciate you testing this to the absolute limits.
Much love 👌
Fo shizzle
I think it's a sweet amp, I like how he optioned it out nice the knob is awesome and has clip light... Why don't all amps have clip lights it would take so much guess work and woofer damage out of the equation...it can't be expensive even my trucks little $90 Toro r2 has one on the amp be nice if it was on the OPTIONAL knob. I just pre ordered the CAB 45! Can't wait but im gonna have to...whaaaa! but gives me time to do the mandatory upgrades I need for going to a true 5k from a APCLE1800. It was a toss up from the CAB45 $379 and a $399 B stock SFB5000 at Audio Apex but I decided to go with the looks and beefieness of a half bridge. I just love the looks of a big ol amp vs how visually un impressive small full bridge amps look.
Well I'm glad I didn't purchase additional protection at .5, either way I was only going to run it at 1 ohm awesome video lovely Channel look forward to you doing a video on the upcoming jp23-4
Even at 1 ohm is no good if you do not have the power supply to run at 1 ohm it will go into protection mode like skar amps do :/ I am glad I did not waste my money on this his amp so good luck with your amp...
@@________GHOST________ I have 80ah lithium I ain't worried.
@@________GHOST________ True that I had a skar rp 1500 and at 1ohm it would run hot as hell.
Thanks again for the video and I appreciate your unbiased information and opinion on the amplifiers that you test.If we could get the rest of the low life manufacturers to tell and print the truth it would make this industry a lot more respectable.
As an owner of this amp i can attest that it is a beast
How's he supposed to sell a .5 ohm warranty when it goes into protect on the bench?
Thats called marketing
As I explained, 0.5 on resistors isn’t the same as 0.5 on the Dyno. See the Taramps Smart 3 Low Ohm testing video
@@wal I guess my point is even the other amps it's compared to such as the soundquded run at .5 on the Dyno and don't offer a .5ohm warranty 🤔
@@wal wasting your time every time you explain it to them. 🙄
@@msh6865 exactly
loving it. still waiting on mine in the mail.
Comment is from a month ago.
How long did it take to ship to you since day of purchase?
Thus far, Hopefully you received it and have been pushing the shit outta it. Whats the deal??? You liking it or ????
As I thought it's basically a continuous 400 watts in to a 4 ohm driver, thanks for this useful test, I won't explain any further
You meant to say 8 ohm right?
@@WifeBTR123 a 4 ohm nominal bass driver will run at 8 ohms when being used/powerd, it will almost always stay well above its nominal 4 ohm static resistance, basically double, so the amp will only see a 4 ohm sub as an 8 ohm load, it's called box rise, although it's a bad name for the phenomenon
Soon jp will have his own subwoofers out yep jp on top on his game rite now respect
Yep apparently headed that way also more amps
For a extra 60 dollar's go with the Orion xtr 2500
This amp will cost more than the Orion when this goes off sale.
@@Hammerback0 true so the Orion is a better deal overall.
shhhhhhh
The Orion HCCA is still the most impressive, but they are hard to get now, at a reasonable price ,good job D
The HCCA 3k is essentially a 5kW, so yeah it’s a beast
Hey Wilson, you need to get your hand on a Chinese DSP plug and play amp like puzu. I seen 45w rms and 60w rms variants per channel at 4 ohms. Makes you wonder why the the big name companies that makes these mini amps don't make plug and play options.
The Chinglish is actually pretty good I'm surprised👍 Looks like a good bang for $ solution. Cheers BigD!
Who has the most efficient amps?
Thank you
Let me know what u find out about this im also looking for ok sound quality too or i would defo get the taramp that has 91% at 4 ohm if u want to send you email we can stay in contact i know quite a bit on the subject now
Running at .5 ohm daily. Love this amp.
Running it at .5 on a DD 9515 in a custom box and it is No Joke!!
Hell yeah ! I THINK HE KILLED IT ON THIS AMP TO!
The BASS KNOB alone made this thing a WIN WIN WIN!
I can't thank you enough for your videos, spending a couple hundred dollars on an amp n hobby is hard for me to do, but years ago I had a U.S amps vari loud 150 half ohm stable , I've always regretted getting rid of it n these videos is why I bought my down 4 sound jp23 , everything from the look to the "king of all bass knobs" lol I appreciate you, sincerely Rich fish Pontiac mi
👌😬👍
The nerdy guy in the corner says "yeah, I like my watts clean" thats why i run my amps at 8 ohms. LOL
Nobody wants dirty watts 🤣
I’ve always kinda thought that most home audiophiles were of the 8 ohm breed and car guys were sub 4 ohm type. Idk just the way I was brought up in it
@@mikemarkel9203 there is plenty of home speakers that are 4 ohm. Most are high end.
@@caseytbss Oh I'm aware, i did the 12 volt side for over 15 years till my body couldnt twist and bend like that anymore so I wandered over to our home theater side of the store for about 5 yrs.. Everyone have a safe and happy new year! anything has to beat 2020!
Fk that! Im steeping it up to 32ohms
Once again honest un bias testing
You go boi !! JP23 just killing it 🔈🔉🔊💨💨💨💨 you are the best
Big D Wiz 👍👍
Thanks for watching and commenting!
I actually just ordered one will be running it @1ohm @15.8 should be very solid on 40ah eh5 back by 390a
I would like to see more 8 ohm test on amps to see what they could make when we have that impedance rise.
Sure thing
Can you do 2020 best gem for a review of last year plus I love your new format with the the protection gauge sitting for us to see. Thanks for keeping it real.
Can you test the planet audio bbd-4000 it looks like it’s built well and is reasonably priced at 179$ on Amazon
Damn BidD this amp is killin it! It's an awesome deal for the price, I'm hoping with all it's success Jp will keep it in this price range though.
To keep up with full bridge technology and price per watt price has to remain similar. ..great amp was surprised all around
now that is some impressive stuff, sad it went into self-protect at 0.5 however still impressive for damn near 4 kilowatts. "BRTUAL" test indeed, lol.
Great vid. B)
You gotta get your hands on the soundstream human reign and triple x series dude i know theyre rare and expensive but we believe in you😁
Thanks again man appreciate the review and got my truck back up cheaper then expected ! More money for audio
Thanks for your work. Very informative. Always use you vids before I buy. Thanks again
I wish someone could help me. I have a 2019 impala premier. Long story short I’ve already completely upgraded everything. 3 amps and a yellow top battery in the back. My troubling question is I have a pacaudio amp pro GM 61, I believe, which ever one works for the Bose system and my question is I have to turn my front and rear amp down because I have a continuous shhhhhhhh sound like when your TV is turned all the way up and there’s nothing playing, that static sound that you get. Not a crackling sound but just that quiet sound. I have been told it’s called white noise. I know there is someone out there that can help me fix this problem. Pac audio told me to switch the little voltage button on the unit and it did drop the static sound a little bit but it is still there. I need to figure out the problem so that I can turn my amps up. There should be no sound coming out of those speakers till the music is turned on. Can someone please help me.
Wow 4809 watts from a 2300 watt amp. This is an unbelievable amp at a great price. Congratulations JP
"all that blue" is from the oil on your lens. even if youre using a phone, go get some higher end sunglasses cleaner to get rid of it. You might have to clean it 2 or 3 times before it goes away fully, but it will go away
Seems like a decent amp for the price but my OCD would be going crazy with all the misspellings on the box.
What kind of wire do u use big D?? Knukonceptz?
Why do the voltages not match? Which one is wrong
EDIT: I see the voltmeter under the amp is also reading 15.0 at idle. So the dyno is reporting wrong voltage
I was wondering this as well. I believe the dyno measures right at the amp input terminals, which should be the same location the bass knob gets its measurement?
Good looking amp and good price. Was thinking about buying one but I’ll stick with the soundstream xxx series amps and the old school us amps Thankyou for the video
Can you explain the differences between certified, uncertified, and dynamic?
It literally tells in the screen
I have a powerbass xma 1205d.
It works great and sounds clean.
I'm running it at 1 ohm to 4 4 ohm 10 inch kenwood excelons in a sealed enclosure.
The manufacturer claims over 85 % efficiency even at 1 ohm.
I would be curious to see how it would perform on the amp dyno 👍😎
Very nice. Seems like an overall great value. Thanks big D
Can you please do a amp dyno on the bass 12k .5 ohm please
It's lowpass filter is 35-250 but I just wish it played below 35 Hertz! The Orion XTR 2500 D would be pretty comparable but goes down to 20 Hertz! About $200 more though so idk maybe two of these is the way to go!
The low pass filter filters out frequencies above 35 hz, not below 35 hz, hence why it is called a low pass filter. This amp plays just fine below 35 hz, as do most amps.....unless there is an active high pass filter engaged.
I miss the U.S made amplifiers. Sad misspelling and copy technology . What happened to pride of making your own product and designing your product
Because he doesn't know how, he's just a salesman. Plus it's easy money to sell something that is a copy of common design & only change the cosmetics rather than the horrendous costs to built from scratch.
Thanks brother for amp review test.
Ever notice that lots GM cars had 10-ohm speakers?
Would you dyno the Taramps DS1200x4, there is not good RUclips content from the USA on that particular amp. I'm looking for a powerful budget amp and this one seems to fit the description.
Would love for u to test the ct sounds amp,, like their ct series (black amp). I have a 1500 only cuz it was so cheap to pre order, but their T series ( grey amp) disappointed me.
Thanks to this video I went ahead and bought one
Seems price just bumped to $349...
Bought the JP23 V1.5, came with this oil inside the "guts" not water but some kind of oil. reached out to D4S and nothing back. opened the plate and tried to clean the oil off but it was everywhere. Asked around on reddit and other forums if anyone had the same issue!
Jp 4.100 4 channel sounds great i might just run jp amps almost like us amps all it needs is the Plexi glass back cover
You should start to do ratings at 12v,cause we all know there's tons of people buying 1000+watt amps and using no extra battery or alt.
I know you shouldn't but people are and it would be nice to know wattages at 12-12.4 volts.
When I finish my new test bench, I'll have variable voltage so I'll be able to do this. I can do it now, somewhat, but I'll have 400A of power supply plus lithium on tap
Wow 453.3 amps ! You had better have a decent electrical supply because she's hungry!
you should dyno the db drive wdx 3k ive always wanted to see a dyno and even more now that i have this amp
Running 2 of these on 4-12s at 2 ohms and they are going strong. I play every kind of music you can imagine and the knobs are perfect for on the fly bass level tuning. My only question is “ why are the lights on the remotes so frikkin bright”
I wonder what happens to the amps after hes done with it I wish I could buy one this looks like a real good amp 👍
You should dyno some concert amps. I have Crown Itech 12,000 watt amps.😁
Word
I would love to see that to
That would be an awesome idea but we cant run them below 2 ohms. Last i check they dont even go down that far but it would be interesting to see
@@chadbeverly4926 they will go to ohms all day long...
Really like these amps. Run 2 of them on 4x sav2 15s in a 4th order C pillar
New version review coming this weekend 👌
O YEAH I LIKE THIS DOWN4SOUND AMP!! VERY GOOD AMP👍
Thank you!
DOWN4SOUND IS THE BEST
Why is first attempt at 0.5 failed, but somehow after it went through? BTW love this amp and your vids.
I tried 3 times and it protected 2 of the 3 times. Not a bad thing though
@williston audio labs check out the stetsom high voltage stuff. I would LOVE to see their high voltage lineup get tested. even if you only have 4 or 8 batteries in your bank. it would be a lot of work but way worth it imo.
Thanks for 8ohm test again! looks like for example my recent hertz hdp4 amp better for 8ohm. i suspect. should test it properly like u :) or taramps smart 3 for subs
Can you tests the SKv24500 on low ohms?
Florida and Nevada? It is just a hunch but there seems to be something fishy. Neglected voltage, healthy voltage, thief?
Beast of a amp
Hey @WillistonAudioLabs, can you please do a dyno video test on a BavSound Amplifier? They claim it’s 1300W RMS but I highly doubt it thanks!
Hifonics brz 2400 and Soundqubed q1 2200d have the same board layout. It's pretty common on a lot of amps. You gotta go with Rockford or JL or some other higher end amp to get a unique engineering design.
Fo sholo
Car audio company: Hello China we want amp 2kw/2ohm
China: OK, we have this PCB and with these parts it can make it.
Car audio company: Hmm, do you sell this to other companies?
China: Yes
Car audio company: Ok, so it is working design. Please change the cooler a bit, put our logo on it.
China: OK, anything else?
Car audio company: Oh yes! Write on it: designed in USA!
China: Done
Car audio company: so we just designed our brand new amp
And some people still thinking jp is great😂
@@promo130 Yeah it is sad :)
Engineered & Designed by the Massachusetts Institute of Technology, Made by Hoo Flung Poo Industries. This amplifier go to any ohm you want. You no buy you leave.
Good afternoon, I have a earthquake subzero 10 inch 1,500 watt sub with a 1,600 watt kicker amp connected to it and I am running a 1,400 watt cable wire, I am not getting much power out of the sub, not sure if it's because of the low wire wattage or if I need to get a stronger amp, could you give me some advice of what the problem could be and how I can fix it or make it better, thanks
Would love to see you test the new audio apex/cab 45 when it comes out looks to good to be true
I own one, I bought it the day he released it, I live in vegas, I was pumped to get it, but that turned out bad after it over heating all the time in the summer in vegas, it just cannot deal with heat at all, at 120 degrees it turns off, and I am done for hours, I assume I got a first run lemon... my Kenwood 1800w never failed... so who knows, but what REALLY pisses me off is the Reviews on Down4South are filtered and my Review was not posted so do not take what is on D4S at face value.
Yo that ending clip :o
haha love the spell check. Looking good brother
Great video Big D . thanks for posting part 2.
He misspelled ENOY on purpose if you ever watch his live videos.
Splain please
Thanks for the content BigD. I was sitting here wondering what the Orion 2500.1Dz would do in the low ohm tests? Might be worth a video?
I wouldn’t run XTR-2500Dz under 1 ohm. The HCCA 3k, yes, but not the XTR
Please, test the Soundigital Evo 4.0 amps
I really hope this last since I paid $380 at half ohm
Most to all china amps MOSFETS WILL BURN OUT IF IT CONTINUE TO GO INTO PROTECTION MODE LIKE WE ALL SEE HERE ON THIS VID SO GOOD LUCK:/
No worries dude - I only bump da bass at 2am in the morning when it's foggy out so that even if people can't see me they can hear me. LOL I'm joking of course (I'm not one for waking the neighborhood that way).
Yeah man respect ✊
