American Warriors Hifonics Eagle four channel oldschool car audio amplifier power test & sound demo
I did another classic hifonics car audio amplifier amp dyno from the american warriors series.
I used continuous and burst test signals.
50Hz for bass performance test and the typical 1000hz sinus dynamic power signals.
What do you think about this little 4 channel amplifier? Do you have more information about this classic amp?
Let me know in the comments!

Another nice oldschool car audio amplifier from 1996 arrived for a dyno run and sound test! Thanks to people like you the videos keep coming up! The Infinity Kappa 202a did a good job on the amp dyno!

What is price for that piece. 1000 watt amp.
Wird ja auch langsam Zeit....🤪😉🤭....
Fun Fact: My father was the founder and managing director of now-defunct AMA Audio Mobile Acoustic, and designed this amplifier.
Thank you for the information, are you or your parents still into car audio? Das ist sehr interessant 👍 Schöne Grüße aus dem Norden 😊🤘
All the research I could find was pointing towards sometime in 2008. I could not find anything definitive but I'm pretty sure it was released in 2008. Also the Brutus and Titans switched colors meaning an older Titan is black and an older Brutus is silver. Indicating this is definitely made after 2006. Hope this helped. Also in the write up was "The new Titans are better sound quality because they are A/B Class but the Brutus draw less current because they are D-Class."
Guys, I have the Fosgate Punch 800a2 amp, should I buy 2 or 4ohm subs?
How many subs will you buy? If you go for one sub I would get a 4 ohm sub and connect it bridged mono 😊
I still have one 60.2 and one 100.2 bought new..I used to run a 3 amp system but one of the 60’s fried when a wire came loose..Sounded Amazing
Hallo Audiokeller, ich habe diese Endstufe bei Kleinanzeigen gekauft und habe eine Frage dazu.
Moin! Na dann raus damit 😊
@@audiokeller1975 habe die eingebaut. Die Endstufe schaltet bei etwas mehr als "zimmerlautstärke" ab. Mache ich leiser geht die wieder an. Andere Endstufe angeschlossen und alles geht. Kann also nicht an der Verkabelung liegen. Was kann das sein ?
Wird die Endstufe dabei sehr warm? Wie sieht es bei der genannten Zimmerlautstärke aus mit Vibrationen? Ich könnte mir noch einen Wackelkontakt am Remote Eingang vorstellen , so einen Fehler hatte ich mal an einer alten pioneer Endstufe.
Wird nicht warm. Vibrationen sind auch nicht vorhanden. Wenn die Musik leise ist, läuft die. Ein "schlagen" mit der Faust auf die Endstufe ändert auch nix (Wackelkontakt €
@dfgert8105 dann fällt mir erstmal nichts ein, was hängt als Last an der Endstufe?
I have several of these and punch in various powers. Just ordered a very clean one w caps and punch control (which I usually make my own). Gonna put it on 2 JL 10’s. Can’t wait to hear it!
I have this same amp and replaced the two small caps on that PIM board, Luckily I still had some trace to solder to. I know you can get a replacement board from crazylogic007 but can you go into detail how you repaired this amp?
Yes, I know the guys who have spare boards for this amp but I am located in Germany, shipping is way too expensive ☹️ but I rewired the damaged traces of this board, if I remember correctly, the traces were for the opamps power supply- I have to rewatch my own video 🤘😊😂
@@audiokeller1975 Oh that's to bad about the shipping, I have a punch 45HD that was repaired with one of his boards and it works great. I pretty much got lucky with my 75HD the caps didn't corrode to much of the board.
Got one of these for 75 its a 600. Ive had it in my closet for years and was thinking of selling it for 150 until i seen them on sale for 350. Might hold onto it or maybe sell it and get a whole new system. Atleast part of it.
Hi i have a question Will this amp be fine also for a home stereo system? Any other models worth to be tried? I love the way they are designed and built a lot Thanks a lot
I still use a punch 360a2 for an outdoor system with a big battery 👍 if you are going to use it at home i suggest a strong heavyweight powersupply 😊
@@audiokeller1975 hi thank you for the very kind and valuable reply But what about the sound Is it good? I also have another idea in mind Bypass the internal SMPS and add a mains transformer plus a diodes bridge I am a little on DIY
The sound is great in my opinion but that doesn’t mean anything, my ears are capable of hearing up to max 14.5-15kHz , but I really like how those old fosgates sound 👍
@@audiokeller1975 hi thank you very much again Same hearing also here as i said i admire how the best car audio amp are designed and built I will look for the model you mention I will try both a powerful 12V smps and some other solutions Kind regards gino
@gino3286 also Check the ix dsm series Amps from mid 90s , the earlier ones had problems with the 10uF 16V SMD capacitors which started with age
What is the + and - rail voltages on this amp?
The last time I had this amp opened on the bench is several months ago , i cant tell ☹️
I look at the number on the caps. (Voltage) multiply by .8. And thats my guess number I can tell you wattage wthout turning amp on..mostly
When your saying a voltage..are you discussing p-p ? As in 25v rails?
I say peakvoltage then divide it with 1.414 to calculate with RMS voltage to get the power.
Made by zed audio
Yes zed
Let me watch..and see
Eine sehr schöne kleine Endstufe. Leistung ist für normale Lautstärken mehr als ausreichend. Klanglich fand ich die damals wirklich gut gelungen. Ausgewogen, feinzeichnen konnte sie auch. Nicht super spektakulär und auch nicht schüchtern... Tolle Endstufenserie... Preislich waren die nicht schmerzhaft. Top Video👍🆙️
Was this a Zed built amp, class a/b?
I can’t confirm that 100% but I think you are right because it looks very similar to my little hifonics Cupid which is a ZED amp 👍
yes, these are Zed amps
MTX THUNDER X504 Is it comparable to Rockford? I'm interested in buying it
I am sorry , I don’t know the x504 ☹️
👌
Old Fosgates are the shit. Newer ones don't compare. I used to run two 15's and two 8's of a Punch 45x2 back in the late 80's. Never tested the output, but it was loud as hell and the s ubs moved
I had Rockford Fosgate 300 4-channel. With fan built in it. And great power and sound the more you added the better it did.
I think you talk about early 90s RF amp? I never had one of these, but heard they are impressive 👍
Are all Hifonics amps so bad in efficiency ?
Around 60% or more is typical for a class AB amp I had tested so far. I tested other class AB amps which had >70% . Different thing is class D with more than 80%.
Strange the amp needs 55v to do 100+ watts..the power 650 rockford has 55 v rails and does 175 watts..that means the chinese hifonics amp is current limited.
I quickly checked this video and it looks like at 55 volts it does 175 Watts just like you're saying the power 650 does. So, it's basically the same power output at the same voltage. What exactly do you mean by the Hifonics being current limited? Do you mean a regulated power supply section?
@@JasonWW2000I need to rewatch the video..because you called to my attention ... I might have put my mouth in gear before my ears had the info..haha. about my ohms law based decision I can tell you that you can manipulate resistor values and design the amp to work better at different imp loads and also b+ voltage level..regulation is mostly unrelated . Thats where the designer picks a voltage ...and anything above that gets thrown away. The purpose of this is under load the voltage of a basic car will swing with the beat of the music..with regulated amps..it doesnt matter if the voltage swings from 12v-13.8..the amp will get ( 12v..) when in theory..a non regulated design..with an upgraded alt and wire and battery bank.. will work way better with 15v stable.. but you must have the power..or chances are..youll blow up the amp..and or smoke the woofer.
Nicht nur die Leistung ist eine wichtig Metrik, Klirrfaktor ist auch wichtig. Kann dein Oszi das messen?
Moin👋 Das stimmt natürlich , allerdings lasse ich das aus mehreren Gründen weg und teste nur bis zur clipping Grenze . Der erste Grund ist der Mehraufwand, mit fehlt einfach die Zeit. Der zweite Grund ist , dass ich mal einen selbsttest mit Musik durchgeführt hatte und musste mit erschrecken feststellen, dass ich es erst bei ca. 4% heraushören konnte. Bei purem Sinus natürlich eher. Dritter Grund ist, dass man mittels Ruhestrom Justage den Amp besser oder schlechter dastehen lassen kann also mehr ruhestrom: mehr Wärme aber weniger Verzerrungen. Daher: einfach ein paar Watt abziehen dann wird’s weniger 😂 ich habe das mal durchgeführt mit einem anderen Amp und bis zur Clip Grenze liegt man meistens unter 1%, das sieht bei den burst Messungen anders aus, da lasse ich bei den letzten cycles auch mal 5 gerade sein 😄
Good morning(dyno) 😂😂👍🆙️😉🥳
You're going to have to tell us how it sounds. What is your opinion on it?
Hey watch the video again - the sound test is also included 😂😂👍👍
@@audiokeller1975 You can't do a sound test through RUclips due to its various forms of compression and manipulation. Plus the speakers I'm listening to it through are not exactly the greatest. I never understood why people think you can do a sound test over youtube. You literally can't. Especially not an amplifier test where it's very difficult to hear the subtle nuances. Basically all amplifiers sound the same through RUclips.
My guess is that it's going to sound just fine considering it's a decently priced class A/B design.
That’s absolutely correct, the limitations of RUclips make it impossible to tell how an amp sounds, you can just compare them all with this limitations. On the other side: room size and speaker placement will do much more differences than RUclips can ever create and it’s also a different situation in a car especially in the deeper frequencies. All that was the reason I asked if I should quit the soundtests.
@@audiokeller1975he's asking you on your experience, how do you think the amp sounds? It sounds good as rockford?
I'm curious too😬😬😬😬👍🆙️
Great video! What is that electric box at 11:44 called and is idle current always done checking distortion or is that set by manufacturer for some amps ?
Thanks 😊 I think you mean my small power supply? With this thing I limit power consumption and check the idle current or do trouble shooting avoiding too much current flow if there’s still something defective. I don’t know how manufacturers set the bias. Sometimes Rockford set the bias a little high which is good for soundquality but generates more heat. Setting it lower just to the point where distortion disappears produces less heat. You can also set it without scoping the output signal but watching the idle current. Run the amp very hard after setting the bias and let it cool down if the amps bias isn’t drifting away all is fine 😀
@@audiokeller1975 awesome! Thanks
Servus kannst du mir einen Link schicken von den Widerständen schicken ?
Moin 👋 jetzt hast du mich erwischt, das ist schon sehr lange her. Ich suche mal aber das war in einem amerikanischen online Shop, der auch nach D liefert. Entweder mouser oder digikey..
Also der Hersteller nennt sich te connectivity , die Bezeichnung lautet für den 3.9 Ohm : te1000b3r9j , Musst du mal sehen wo du den herbekommst, preislich waren die ca. 70 bis 95€ pro Stück, den gibt es auch als 1 Ohm, aber ich habe die Rechnung nicht mehr.
I have two but one says punch, any other ones says power 360a2 and 360a11
@@zephmattix438 if there is the same amp with power instead of punch you have beefier power terminals and the filters have a slope of 24db instead of 12db.
I have two but one says punch, any other ones says power 360a2 and 360a11
Ich habe da so ein ähnliches Problem mit dem Airfryer des Typen HD9240. Er heißt aber der Lüfter will nicht laufen. Hab neue Platine geholt und auch neuen Motor der Motor bekommt auch Spannung läuft aber immer noch nicht woran kann es noch liegen?
Moin! Der Motor bekommt Spannung und läuft nicht? Ich hätte jetzt ein Relais vermutet, welches vermutlich den Motor ansteuert aber wenn Spannung da ist und sich der Motor nicht regt, liegt es am Motor - bist du dir ganz sicher mit der vorhandenen Spannung?
Die H 400 hatte ich auch mal im Auto. Ich weiß aber nicht mehr ob es die Esprit war oder eine andere Version. Ich mochte das Teil, auch schön anzusehen mit den Spiegeleitransistoren (TO-3 Bauform) und den LEDs auf dem Board. Danke für das Video!
Gern geschehen, die ist wirklich zu schade um sie versteckt zu montieren👍
i found two in my closet i bought new in 1999 or 2000 forgot i had never usedlol!
I dont do it like that. I put flux on the back of the fet and heat the strip slowly until i see the solder flow then i push the part down and hold the part on top with pick tool making sure its tight against the strip then I slowly let cool
I don't know if you're looking for advice or tips. A couple things I would do different would be to use a little more soldier under the mosfets so that you can clearly see it come out all sides. Second would be to use flux. The small amount of flux in your solder will quickly get burned away within a few seconds. Third would be to heat the mesha a bit slower so that the heat can more evenly spread. In the video it looks like you heated one area very quickly. Forth, be careful to not push down too firmly on those resistors. They are quite easy to snap in half. Good job. I've never really looked at this generation of amps. Internally it basically looks just like their older DSM and black and grind amps. Probably just a few small differences in the preamp. section.
All hints and tips are more than welcome 👍 I used multicore flux solder which I still own from the 90s 😄 to keep the video. Little shorter I made a cut , I heated the Mehsas slowly.
@@JasonWW2000 yes. Basically a dsm with xover .. and i agree..i never heat a part enought to melt solder on its tab..not directly. The part will be compromised..
Awesome video
Thank you ☺️
Wie cool ist denn bitte, bei der Reparatur dabei zu sein... Man fiebert richtig mit..zumindest ging mir das so😬 This Rockford Amp will survive for a long time... really good job, dude!!! Solche Videos kannst du gerne öfters machen... Meine besten Grüße auch an David Stevens 🫡
Thanks 😊
So if I understand it well, the amplifier puts out about 1000w rms at 8 ohms per channel?😳
Yes, both channels driven 950 Watts , single channel driven 1050 Watts 👍
Thanks for sharing this with us, always appreciated 👍 old school RF FTW
Very cool. Back in the 90s I was friends with a somewhat successful drug dealer who had a major car audio addict. Used to get all sorts of free stuuf from him because he was constantly upgrading and trying new stuff. GOt a couple of round 12" SoloBarics a Punch amp, and there was an MTX amp, forget the model, but it was a cheater amp and was designed by an engineer their hired away from Fostgate or maybe Kicker, used to really pound
Sounds like it was the MTX amp i really want to dyno - MTX thunder 2300 ? There is a nice video made by Dereck- oldschoolstereo.com
@@murrayshekelberg9754 the amp was to be the punch 300. But the designer went down the road to mtx and it bacame the ta2300..yup my friend john pleitz
@@audiokeller1975 I've been wanting to find a Thunder 2300! Great video btw, Loved seeing the repair process. I have a punch 100dsm that needs work.
@@jodyzung6455 what’s wrong with your 100DSM? Is it the older DSM or Punch 100 ix DSM ? The older ones feature additional boards with SMD devices on it. I had one of them repaired and it happens very often that the silver SMD capacitors leak out and create damage. They are 10uF 16V.
@@audiokeller1975 It's an original 100 DSM. I bought it used for cheap because the seller said one channel didn't work. That's all I know at the moment. I'll hook it up soon and see what happens. Hopefully I won't damage it further :)
Thanks for the cool video. I have a few 1995 punch amps that need repair, no burns on boards. I don't know what is wrong. Thank you for your informative videos.
Maybe mosfets?
MosFets, drivers - first check them properly to know if it’s worth fixing. In most cases it was worth it 👍
@audiokeller1do you have a video on how to check mosfets and drivers?, thank you buddy.
@jsnjcnt infinity think so , but it’s easy if you have an meter with diode check. Check MosFets and drivers at power supply section and also drivers and mosfets in output section. Get a small power supply with current limiting and limit the current to around 3-5 Amps. Connect amp and check how many amps it pulls. Turn all bias pots full ccw and recheck 👍
Ok, awesome I have a Fluke multimeter. I think it has diode check. I need to get a variable power supply. Thank you for the help.
Thought this video was about a Gpu
I don’t remember that hifonics made GPUs 🤔 I still own a 1080ti 👍😄
That's one damn good-looking gunshot of internals right there best quality built right there
Man you sure find some really good Rockford fosgate amps do people send you those in for free for you to do a dyno test on them do they donate the ants to you to keep?
This amp is from one of my best supporters and I love fixing them if still possible. Right now I am editing the repair video 👍😊
Dyno...dyno...dyno...😬😬😬 i'm really exited ...🥳🥁🥁🥁😎
I sink i can hear a german aksent
That’s correct 👍 More than 30 years ago in school was the last time trying to sound like a British or American guy 😂😂
I think you will fix it🤓👍🆙️
Does this amplifier say made in Korea?
I inspected the amp but there is no hint where it was made , just „ hifonics USA „ is printed on it
Ou ha..... da gab es mal einen Equilizer und Tuner(die hatten etwa die Größe einer Audio Kassette...nur dicker) je an einem Schwanenhals...und sollte um um bei 1985 gewesen sein.
