To get 1300 Watts for $100 dollars is a budget gem. YEAH BOY!!!

Wow!!! 2129 watts at .5! That’s a beast at $99. Couldn’t believe it went .5 ohm without going into protect, Keep up the solid work Big D!

I think you should include a watt per dollar category in your videos for all those new amps that you test 😁😁 so its easyer to see whitch is most cost effective,...just a suggestion 🙋

I really enjoy watching your videos... you do an AWESOME job all the way around. After I graduated electronics school in the late 80's I started repairing car audio for an Alpine dealer and amplifiers have always been my favorite . I think this amplifier is a beast...especially for $100 but now I couldn't find anything around that price it had more than DOUBLED! I looked hard for a deal because I was just wanting to play around with it as I have tons of name brand amps. I finally bought the same amp on an Amazon deal (DEC 7, 2022) for $106 but it is sold as a "Facmogu 3000W Max Power Class D Mono Channel Subwoofer Amplifier". It has the same case with the 6800 watt and 8808.1D logo but no brand is on the amp or the box it came in. The paper manual is also the same . I checked the guts and it is exactly the same as in your video even with the AudioPipe wiring except some of the caps are now Zhuohao brand...not familiar with that brand. I powered it up but haven't got to test it out good yet...but SOON! Thanks for making these videos and I will continue to follow your channel awaiting the next amp review.

You'll see that those sections, after being populated by the pick-n-place machine and soldered in the oven, are then placed as verticle daughter cards on the amp. They do this to keep induction low by keeping all the signal components closer together. This is typically so they can get away with the cheaper standard 1oz copper layer rather than having to jump to much more expensive heavier weight copper layer, which would be needed if all the parts were laid out over a larger PCB area. Crazy power !

I've been running this amp on 4 500w subwoofers @ 1ohm for about 8 months with no issues. Clean deep bass with gain under half way. Thing is, I believe I got the last one of eBay...they have been out of stock every since.

I have to admit. I "like" you videos before I watch them because I know it's going to be awesome.

Well, well, well what we have here? $99 amp getting it done. Very impressed, for sure. May have to get one and see how long it'll last on two 500wrms subs. Definitely seems like a good daily banger. Another great video my man. 😎👍

Big D, Wudi saw your dyno of their other amp and said "Naw man we can't go out like that". Enjoyed the video.

Wow!!! I am just completely shocked you didn’t wind up with a 100 buck paperweight!!! Great video Big D!!!

I bought one of these widi 8808.1D amps thanks to your tutorial. I must say I'm impressed. I paid a hundred bucks on eBay and the amount of bass it produces I had to buy another one

Things have changed, 1300 watts at 1 ohm would've been 1300 skins back in the day this is 100 - ish shipped

For the 2 broken off portions.. you can see that there is 2 other small boards placed vertically on the main board... these 2 smaller boards would likely have been printed out of the main board.. and then made it so they could easily be snapped off and re-positioned during production.

This is a win for guys like me who just want some bass. And not trying to shake windows

The broken off sections of the board are the 2 pieces used as daughter boards on the amp.

Something about watching 4+ subs moving together is so satisfying

You can see the board he removed. It is a vertical component mount. At 10:51 The initial flyover shows both segments. One is at the upper right of the PCB, likely the input pre-amp section from the location. The other stares you in the face at the above noted timestamp. Vertical PCB sub-assembly mounts conserve main PCB "real estate", and are also useful if the original circuit gets 'massaged' after it initial release without the needed space to implement it and not wanting to perform an entire new layout. They look the same size as the missing pieces you referenced. Easier pick and place and a simple breakout once the PCB gets to the customer for final assembly. Many of these get their thru hole parts put on by hand since the count is not very high and the labor is not very costly.

I love the way you explained everything bad or wrong or good about those cheap amp.

I use your channel to escape politics! 🔊

a c note for rated at 2 ohms/clip is still decent. and it gets close enough for that price. even if the finish quality is.. rough. i'd rank it a flea market king though.

open a hole in the planet! ma man, u da real MVP!!! you gets a thumps UP!!!

same brand of caps as the D'amore amp you just tested.👍

Those broken off peices are the daughterboards on the amp, just easier to print it all at once

Excellent review, Back on fleab for $112 and Amaz for $233 wow Honestly this budget amp kicks lots of name brand amps you know what. They adv a remote bass knob but is Not. Again Excellent Review on this amp. Even at 1ohm beats namebrands that cant handle the loads. Wow wow wow .

899 lmfao they ain’t right! I guessed 1200 when I saw the 4ohm load definitely worth the $$$

The Low Pass/ Subsonic filter comment killed me! I LOL'd.

the chunks out of the board are the driver cards , its a way to save cost in making them i guess .

Just reliving some old dyno’s. A lot of people don’t know this but I am fluent in Cantonese and Mandarin Chinese. I know what that certificate said. It said “YOU BUY NOW!!!!”.

Dawn you have to be the very first person to watch to get one of these amps that are a good value it seems like 5min after video played there gone and you will never find them again. 👍✌️👌 Big d sales amps by the ton if they were to give him 1percent of every sell he would be a multi million.

Well it looks like there is a new king of budget amps.

Holy Hell Big D! A $100? These are remarkable numbers from WUDI. We appreciate all that you do. Better believe I'm getting one. $100? Jesus.

Pink Panther boom tube is the bomb:) wish I ownd the cd from back in the day

Excellent review on Chinese amps. I've had "3800w" mono Wudi amps before but they went boom connected to just 1.5 Ohm load.

Goodlord that .5ohm test trying to kill the wudi but it passed🤣🤣🤣I'm very impressed the price bout to double after this🤣🤣

this amp is a repairmans dream come true if you know what to look for. the audio output generation circuit is isolated by optocouplers from the actual drivers and final stage hence damage never goes further than the optocouplers! in my experience its the closest ive seen to modularity in an amp build. this board design is quite generic and generally makes 1500w @1ohm. there are weak spots tho and could and should be beefed up before use. if anybody has Perrys guide, its generic class D type 4

What the WUDI redemption is going on here? I expect to see 2 of these in the Hot Rod!

Flirting with 5 cents per watt here. Impressive. Looks like there are four left at $110 apiece as if 1:15mst. Good luck folks!

So reminds me of the Old school Punch45 ❤

WUDI WOOO!

After this vid they are going to pump the price double for sure

Can you do some 20hz or 25hz tests on your amp dynos to see which amps can really slam the lows and which ones fall on their face?

This is the revenge of WUDI WUDI TO BIGD: “gotteeem goooteeem” 😂

Just an update. Had this installed basic 4ohm load for over a year. This thing has taken all the abuse. Set gains with a scope so it's been loud and clean driving a single 10 in my truck. Every time people hear it they say no way that is just a 10... So far it's lasted longer then my old school Kenwood monoblock.. very happy I found this guy on YT.. what should I upgrade to next

Amp is available for sale again :) I scooped one up for $105.

Those break points on the pcb are known as 'mouse bites'. They route the board as normal (the smooth part) and then drill the tab ... then break the board out of the panel after it rides through the reflow line.

Wow surprise surprise! 🤣Good video Big D!💯

The x2 bits of the board that seem missing are actually used as the virtically mounted peices of the amplifier board.

I mean, a lot of what is checked on this channel is wayyy off. But at 4 ohms, it's still less than 20% off(18 and 14% under), then at 2 ohms, it's only 6.7 and .11% under. Do any of these provide variances at all? these may still be within what should be epxected.

Awesome review. I would love to see you testing one of the new U1 SoundQubed amps.

100 bucks is a win. My question is how long would you suspect it would last? I got a 92 rockford fosgate 800.2 still going

The cutouts missing from the amp board was a money saver. I'm sure the missing pieces are parts for the 4 check version

Luv that old-school Kicker sub @ 16:12

dude I love this channel. shame I hadn't known about it before. will support u and buy some merchandise

That's sweet for 100 bucks. 2 of these on a set of 12s will have you jamming.

9:05 don’t take away the flex 💪 We love to see dem subs bumb yo! Also, it actually nice to see the subs moving then hear what you thought about the performance 😉 please bring back this segment.

Love the video. Wish I could find a amp there all sold out lol. Keep it up man doing great.

10:43 - They cut those pieces out to make the two attached upright boards saving copper and money. Clever idea.

Wow, incredible little cheap amp. Pretty impressive

Those missing sections ARE actually on the amp. They do things like this so that those knock out sections can all get soldered in the same process through the wave solder machine. Then all the have to do is knock them out, and solder the knock out boards in the appropriate places manually.

I've never seen a 100 buck amp over 2k Heck ive never seen one get over 100w lol

I looked like for that price it's worth it and it would be great if the saying was more compact I love your channel I'm also old school

You know some Friday nights we would donate stereo gear from 3 guys to one guy and take turns cruising..Mercury precis with 4) 12's. Lol. Good times ...love your show .loves those phoenix gold Amps you showed hand built ones ...if you don't understand math you won't go far In Car audio ..we didn't have lots of money. I ran all L A sound Amps till I got out of highschool and had a job. We had to go with sensitivity instead of brute force. No money to power the stuff. We had a friend with an 18" in a dodge Omni 😆. He was the quietest one in the bunch...couldn't afford the amp to power it.. Fake it till you make it. Now I have a general system. DVD played nothing special..been tempted to remove a rear seat and make a subbox you can sit on.

3:15 for those who like it easy... lol

I used to push my fosgate power back in 2002? .5 ohm. When you pounded it it would make a full song before she thermaled. Never quit. Still have it. Early 90's my buddy had 2) blaupunkt 12" subs ( only pair I ever saw) powered by a huge PPI amp. It carried a long ways..we were Into loud outside the vehicle and making the roof dance. Not really into max spl. I had 2) 10's behind my seat and 2) 12's in my bed with the pass through and a camper shell. In a regular cab mini truck..those were the days..bean bag chairs in the bed and glow in the dark stars on the roof of the shell Kid sensation is Back to boom! Dj bass boy Techmaster PEB Then came DJ magic Mike and mc madness. Ohh shitt. Buddies all ran exotic boxes. 4th order bandpasess. I loved conventional boxes. Had to retro vent Oh I ran a eclipse touch screen tape player. For a long time..Into the CD age..no one was cutting CDs? So I could make sweet 90 minute mix tapes for partying by the fire in the desert or the river. Everyone would bring me a cd and say play this...I would say I can't it's a tape player? What ? A tape player? Never had to play others music..lol..CDs skipped In the desert anyway back then.

How often does your test equipment need recalibration/recertification?

10:40 the answer to this question is looking you in the face They have the pcb manufactured with those snapped/snapoff sections which are themselves small pcbs which you can see mounted vertically at the top right and the other is right next to the snap recesses

Late to the party but I found these amps on aliexpress for $85 with $0 shipping - might have to pick one up

Those "missing" tabs on the main board were populated and soldered to the main board in a vertical orientation. You can see both of the "missing" sections in your video. One is located near the power input and the other is soldered to the main board near the place where it was "removed."

Not bad for $100. It did better than I thought it would

I usually think of long term when buying an amp on impulse. That amp may have performed good but what if it only has one or two good bumps in it then shyts the bed? Sending back to China is a pain. I will only purchase on good reputation amps. Enjoyed the video though 👍

Thanks for the videos. This one was a big surprise. But thanks so much.

electronic components manufacturing standards are light years where they were 10-20 years ago, this effect buoys everything

Greetings Big D Wiz.... from another Big D..... BIGDOGBRODAVE of ONE CALL INSTALL here out of Honolulu Hawaii... I started installing here in 1973 when the BIG CHEAP AMP.... was a underdash EQ box with 25 watts... and a FADER!!!!.... I came along at a time when cars typically had only one speaker in the dash and a AM radio so.... quite the improvement. I am currently building an AUDIOMOBILE RACK system.... for fun. I have been watching your videos and I wonder HOW the REAL old school amps actually perform on that Dyno there. I am sure the readings would be underwhelming to most viewers of these times but back in the late 70's to actually have 100 WATTS to power them "100 watt" Jensen TRIAXIALS.... well... People knew.... I owned a pair of MINDBLOWER 6x9 speakers back in the 70's in my 70 Challenger. PERFECT TRUNK for them.... Hunting for them as of late as well as AUDIOMOBILE GEAR. That being said, I recall YOU have a SA 1600 system amp. I wonder if that could be tested. I am IMPRESSED with this WUDI as it appears to be the modern version of the JET SOUND product. Coming from Asia BUT on the low end, I recognize that FONT... in my nightmares..LOL..... JET SOUND products were synonymous with ENGINE NOISE.... I learned a lot of tricks to eliminate engine noise thanks to JET SOUND..... ugggggg..... I LOVE this video so I came out of hiding to give it and YOU a BIG TWO THUMBS UP...... Love your work... Great narration... YOU BIG DUMMY!!!!!!....LOL..... Keep up the great work and you be SAFE and BOOM on... TEST an old AUDIOMOBILE and a ZAPCO... a CRAIG... the 72 watt Powerplay... that thing... and a 500 watt CONCORD if ya can find one.... they blew up a lot.... SANYO... was a VERY EARLY contributor as well as PIONEER... that GM-120 was the best... the Component PIONEER..... back in the 70's... I installed the very FIRST CD PLAYER ever made for a CAR in America, a CDX-P1 made by Pioneer... in Art Rubensteins car a Mercedes, Later I installed the very first CELLULAR PHONE in Art's car. He was the Pioneer rep here back in the daze... His FIRST CELL BILL was over 1200,00 dollars...... I remember his distress...LOL.... Hawaii was the TEST BED for Cellular technology thus.... it came here first them... BOOM.... more BOOM....LOL.... WELL It's 2021 and the cheap POWER is WUDI... and the other end... CRITICAL MASS and maybe ABYSS... a few others... It still amazes me how much power engineers these days squeek out of a 12 volt antique... POWER ON!!!!!! Aloha BDBD

The pieces that are missing from the board are actually mounted upright on the board there, as soon as I opened the amp, I noticed those pieces fit perfectly there, how did you miss that?

No it didn't reach the rated power, But the amp is only around $80 I believe. There's a 5800W (not really) Wu monoblock for that amount. So really given the amps overall output, that ain't too bad. Though it is kinda sneaky using same amp model numbers as Skar. But that's China for ya.

I'm impressed for sure! I will order a couple of those asap. Thanks big d

Damn you Jose Garcia I had to buy one!

For the price, it’s a steal!

The two cuts are a way to save money on manufacturing. If you look closely, there are two "daughter boards" soldered vertically inside the amp motherboard. Those sizes seems to correspond to them. So its likely they just snap them, and solder them where they need to go. 3 boards in 1

No gotcha here man. Outstanding for the budget. Gettin it Done

The wudi strikes back!

Those chunks missing are your vertical boards so they don't have to print those separately. Notice how they are the same size as the slots missing

On the red power wires inside it says AUDIOPIPE lol

Makes me want a wudi over blowpunk for my first upgrade. Impressive.

that one vertical daughterboard is snapped off of the main and used for... something on there built on the vertical chip

the broken circuit board has been used as an extra upright part in the amp

They used the cutout sections of the main circuit board are use3d for the smaller vertical circuit boards in the amp. That way they can manufacture it all at once (in wave soldering) and save

I tell u all things considered ...back in the early 2000s i paid almost 1k for my 800 watt amp ..i would have been stoked if i could have found this back in the day

Hey Big D any possibility you doing a dyno on the Jensen XDA91RB 1200 watt mono amp, I got one for Christmas havent hooked it up yet but curious to see what it could do. Its $98 at walmart which is a steal.

Budget gem 💎 for sure 🤙

You need to test one of the most infamous amps on the market the Zuki Audio Elects 2 and 4ch

I really enjoy your videos, n if you don't have a dyno on it , I'm not buying it. Ty rich fish Pontiac Michigan

You could fit your ride with several of these and just not run them to their max and they'd run all day long. How loud is enough, jeeze!

Not to shabby! I just bought a little budget system with 2 10" Sundowns Ev3. Needs around 1000 @1. This is definitely an option for a Benjamin. Thanks!

I cant believe it did a clean 0.5 ohm certified pass

Looks like they snapped out the board parts and used them in other parts of amp - you can see the missing parts attached as risers.

This amp is perfect to run a single sundown sa12 and Its also the absolute cheapest way to do it.

Yes sir ❤❤❤❤❤

Anyone wanting to know about this amp guts looking like Audiopipe, here is the cross reference into the Audiopipe that is the same as this Wudi : Audiopipe APEL-1200.1

So where do they get the 6800 watt rating? Is there any amplifier companies out there that tells the truth? Do a video on that.
