The Crunch 50SHC is a super high current amplifier made in the early 90's specifically for "cheating" the low wattage competition classes. This amp is rated at 25x2 watts at 4 ohms and up to 400W at 1 ohm mono.
The amp was available from approx. 1992-1994 at an MSRP of $799 USD. These Crunch amplifiers were made by Zed Audio in the USA. Let's see how it does on the Amp Dyno!

Gotta love those knobs where you dont have to fiddle with usin a screwdriver on. Wish theyd bring that back

you probably dont care but if you're stoned like me during the covid times you can watch all of the latest movies on instaflixxer. Been binge watching with my brother during the lockdown xD

@Louis Bronson Definitely, I've been watching on instaflixxer for years myself :)

I absolutely love this channel it just brings me back to when I was 13 and 14 helping my next door neighbor install his amps and subs and learning and just thinking I cannot wait to turn 16 start driving and get my own and the rest is history here I am 36 still installing for myself and friends lol my neighbor had one of these hooked up to 2 12’ volcano red labels and I remember how hard it hit in his blazer

@wadehicks9270 9 лет назад

These are cool videos Dereck I've watched this one a couple times lol old school never gets old 😎

@alfieelvira9336 7 лет назад

And love how the output is so different between his amps

@soundsofnature7015 4 года назад

Also love the vids. You are a boss buddy. Almost nobody in fact I'm gonna say it. Nobody has put more amps on the Dyno than you have and brought so much truth to this industry. Amplifiers are basically very cheap power supplies. The profit margin is huge. The better the power supply the more it cost. Longevity and better products to ensure that longevity cost more money. Don't get it twisted though the sum of these parts even on a 20,000 watt amp are in the tens of dollars. The money they need to recoup is in the design. That being said clone amps and boards are abundant and still cost a pretty penny. This man right here is giving you a good starting point on what brands are and aren't ripping you off. Amazing work.

Yeah, and it's not really that big! I love his humor though, Mr. Mantz that is.

@koos171 2 года назад

Great video! I had this amp and it was a beast. Good sound as well!

@trucavalier 9 лет назад

ohh yeah! I remember these from Car audio mags back in the day. These were more affordable than soundstream, orion etc.... awesome vid and test as usual

@wal 9 лет назад

Thanks for the comment!

@03_austindrake88 4 года назад

I had a MTX Terminator 225 back in around 1994. It was rebuilt by a friend of mine. It was pretty impressive (impressive for rated power) on a pair of JL Audio 10w1's.

@johnalenwork53 9 лет назад

Awesome Video As Always My Friend!

@wal 9 лет назад

Thanks John Work ! Not the most exciting video from a wattage output perspective, but finding out what these cheater amps do is interesting.

@robertvega1110 9 лет назад

Excellent work

@wal 9 лет назад

Thank you sir, and thanks for letting me borrow your amp(s)!

@iceman45ification1 9 лет назад

Not too bad at all. A great example of the build quality and reliability of ZED amps. Great video as always BigD!

@wal 9 лет назад

Thanks Danny Caballero ! I recently tested another Zed, the Zeus VII. Wasn't sure what to think based on the other Zed amps I've tested. I won't spill the beans, but will say it was "interesting"...

@vintagestereobuff7005 7 лет назад

Why are certain amps from crunch and hifonics referred to as Zed amps? Who is Zed?

@iceman45ification1 7 лет назад

ZED is a build house that made & designed amps for numerous companies. HiFonics, ESX, Autotek & Rôdeck to name a few.

@wal 7 лет назад

Stephen Mantz - Zed Audio. Famous amplifier designer from the 80's and 90's still makes amps today. His old school amps are known for their power and smooth sound.

@vintagestereobuff7005 7 лет назад

Wasn't there a guy named Zeff who designed amps around early 80? I think it was Zapco or something like that.

@gregblau8082 2 года назад

I love the look of a big old amp but it always amazed me Rockford was competitive with so much smaller of a footprint

@wal 2 года назад

👌😬👍

@eatsleepbassrepeat 2 года назад

I think that red PG MS Series was originally ordered by my friend Nick for install into his Chevy Nova. He worked at Audio Communications In Monroeville and had a full Plexi enclosure and and amprack with all the wiring going through lexan tubes. There was a total of 4 Red MS series in the install. I haven’t seen those amps since the system was dismantled around 1994.

@wal 2 года назад

The previous owner said it was in a 1994 Celica he bought and everything was completely hidden. He didn’t even find the amps until years after owning the car. There were 2 of them custom for this system.

@sambucci8544 9 лет назад

@wal 9 лет назад

Thank you for watching and commenting!

@FortyTwoAnswerToEverything 3 года назад

Still have my 'ol girl the V600 I bought around '99. Been in about 7 vehicles and 1 car fire (spread from another car). Still use it but she's obviously tired and just can barely push 2 ohms anymore. I may be getting that JP23 you tested a few videos ago.

@2slofouru 4 года назад

Would be really cool if you could find a PPI Pro Art 50 to dyno. The internals look similar to the A600 but I believe they run a lower rail voltage. Had one years back and sold it after changing system plans. Never got to hear it but did look inside and it was nice.

@Van1018s 3 года назад

I had several of these in the 90’s. Although they used the same board is as the 400, the 400 would run all day at 2 ohm and never have a problem. At 1 ohm I always had problems with the 50shc going into protect. I owned approximately 15 of this series of crunch amps and the 600 and 425 seemed to be the most reliable and least finicky about voltage drop.

@99oldsintrigue2 9 лет назад

When do you plan on testing the memphis amp? I think I used to have one. Tha ks

@myz06rocks 9 лет назад

Interesting result Derek. I have seen test sheets on these that take them up to 670 into 1 ohm mono at 14+volts. Was this one 100%?

@thecman26 5 лет назад

Man, this brings back fond memories! I used to have a Crunch 250 and it was INSANE! I ended up selling it... :( BAD bad decision!

@chrisbaze4913 3 года назад

I have a crunch 2000.1D amp and it seems like crunch are not so good anymore. I used to run an older amp and loved it but the new one I have,,, not real happy with it. Wish I would have found ur channel before I got a crunch, I think I would have gone with skar audio. Keep up the great work

@cutraman 9 лет назад

@MyBlowncobra 9 лет назад

I bet with a little more current it would do more power....good stuff

@wal 9 лет назад

Not really. I can supply up to 320A at 14V. This is all the amp has in it.

Im just wondering why did zed buy a zed co

@peloteroification 9 лет назад

Nice, I've been getting my hands on a lot of these old school amps for cheap, too bad most of them are not fully functional because they're so old. I need to learn how to do repair...

@wal 9 лет назад

The ones that were taken care of usually still work fine. These amps were built to last, unlike many of the ones sold today

@peloteroification 9 лет назад

***** And low impedances for long periods of time. lol

@jasonlittou9395 6 лет назад

BigDWiz Could you please tell us the colors of wire for each channel? Im thinking about getting one of these but the guy who is selling it doesn't know what color wires mean what???

@mrlt1 4 года назад

I've been looking for a 50shc those do not pop up at all.

@RWL2012 9 лет назад

Was gonna say this amp was made one day before I was born but I forgot in the USA that means the 2nd of July rather than the 7th of February :-( lol

@wal 9 лет назад

You can flip the date if it makes the video more special to you ;-) . We are strange here in the US, so don't mind us. lol

@Zionslayer1 9 лет назад

What was the amperage pull?

@wal 9 лет назад

I hate that I didn't get video of the current pull! Doh!! And the amp has gone back to it's owner. I'm doing current pull with all the other amps I'm testing...

@timothygray7650 7 месяцев назад

I got a old school Orion amp 800.

@bonthor7515 Год назад

Hey big D would u able to name all the amp that can do .5ohm close to being stable?

@wal Год назад

I'm sure I could name most of the ones rated for 0.5...now whether they will handle the 0.5 resistive load is another question altogether...

@jeanious2009 9 лет назад

Looks like some one re-capped it....I wonder whooo? I got the same numbers as well but my power supply back then was quite smaller than what it is now. I also made some vids when testing it but they are NO where near like BigDWiz (edited and high quality). Thanks for sharing.

@wal 9 лет назад

Thanks for the comment. I'd like to see more amp tests on RU-vid, the fancy editing is not needed. You have to start somewhere. To me the content is more important, I try to keep the editing to a minimum.

@jeanious2009 9 лет назад

I'll get those numbers I got for this amp...I wrote down the amperage the amplifier was drawing at full power before clipping at 1ohm.

@unclemonster48 3 года назад

At one time they were made in hueytown Alabama.

@brentb5303 5 лет назад

So as an old school researcher I have a couple questions. If it is a zed amp why doesn't it say zed audio on the board, they all do. Two why does it act like a regulated power supply amp, not a usual design by zed. I'm not saying this isn't a zed amp, hell it has ceramic gate resisters which is a bingo when looking at a board and identifying a zed amp. What is going on here?

@wal 5 лет назад

Good questions. Have to ask the man, Mr Mantz

@crappieworldlivescanner1114 4 года назад

The old school amps had such a clean sound and most were rated at 60-100 x2 .These junk coming out today aren’t even close in sound.Back than a 60 watt Harmon was 600 bucks and would rattle the room.Theres a big difference in sound and just pure disaster.How can we test sound quality today?

@diawaprolite7967 3 года назад

Crunch before maxxsonics. Zed audio built.

@johnhildebrand1991 4 года назад

Man those amp were expensive back then you can by amp with that power for under 100 buck now a day

@timothygray7650 7 месяцев назад

Oh 2 channel.

@soundsofnature7015 4 года назад

Is that many zero's even possible in THD ? I feel like that might be a bit off. Unless it's literally the best SQ amp ever made. I could be way wrong. I don't know really. Just seems incredible to me.

@Van1018s 3 года назад

That’s how they got away with rating cheater amps back in the day. Give you a power output number at some crazy low thd and then at a realistic 1% thd the amp did 2-4 time it’s rated power. It was strictly for competition purposes, as all competitions had wattage classes. I always competed in the pro 301-600 class meaning the total 4 ohm power rating of all my amps had to add up to between 301-600 watts. So this being a 50 watt amp I technically could have ran 12 of them.

@zumazoomzoom7632 3 года назад

Crunch sure has gone down hill since the 90s

@ehrenkrause9861 2 года назад

The mtx terminator was a cool looking amp, disappointing power output. 😊👍

@wal 2 года назад

Agreed

@urosb82 5 лет назад

Perhaps there was something wrong with this amp (capacitors, soldering etc) cause Germans got their test with lot more power: www.amp-performance.de/1265-Crunch-CR50SHC.html

@baronvonlimbourgh1716 5 лет назад

Hexibase does profesional custom case designs. He really knows his stuff. I think it's free if you buy a speaker from them otherwise it is 100 buck i think. But absolutely worth it. Check his youtube chanel.

@BH4x0r 4 года назад

so Crunch went from an actually decent brand downhill to overpriced junk

@soundsofnature7015 4 года назад

I get that this amp was considered a cheater. They only claimed 50 watts right ? Less even maybe. Boy did you pay for that 400 watts. .00015 thd until you go 3 watts over rated then it's 1.0 THD. In my opinion. For what this amp cost at the time. It was trash. If anyone could compare this amp to others at the time price per actual wattage and thd that would be great. But I'm personally thinking this amp is garbage.
