A few pointers, always remove the amplifier board from case and inspect it, buy a good multimeter with a diode function that will buzz with a short, always check all the mosfets legs with the multimeter, cutting the fets legs to remove it allows you to remove the legs one at a time. Use Chemwik desoldering braid to clean and remove the excess solder. Bend and align the prongs ahead of time before installation of new mosfet and solder it one leg at a time ensuring a straight alignment! Clean the board if residue is present, if compound was on the fets clean the old off and reapply new compound to all transistors, diodes and thermal monitor if it was mounted to the heatsink as well! Some amplifiers will present different issues of failure, I bought a Earthquake 400tx that would only go into protect, I replaced the TL594 with a TL494 since the 594 is obsolete and it works fine. Some amps will have failed diodes and some will have failed voltage regulators. Some need output transistors! Every Amplifier is going to fail differently! I just rebuilt an Orion HCCA 225G4 and it had failed power supply and output transistors! Right now I am working on a kendwood KAC-X1R that someone attempted to repair and I have to do some repairs to the traces of the power supply, it even had failed output transistors! But it was someone attempting to try the repair with no skill level and improper tools and that lead up to damaged traces! If you wish to attempt a repair make sure you buy the proper tools and needed accessories like good desolder braid and plenty thermal compound and at least a 30 watt soldering iron and decent solder wire! Or turn to someone who is capable of doing a repair and has some experience with repairs and the equipment! I would have opted for replacing the entire side or all of the mosfets where the exploded ones were, some people don't and it leads to more cost in another repair! But that is up to you individually!
Thank you for your great insight this gentleman is a joke desoldering pumps work alot better than a paint stripper heat gun for 1 it's not smd although anything surrounding the area of application will most likely fail soon due to the fact he desoldered it all stop providing horrible tech advice if u dont know what u are doing sir !!!
Coul I message you through Facebook or something. I am somewhat new to this and have some pictures and questions. Thank you for your time and knowledge
I have a memphis Mc 1000d that as soon as u hook up power u hear the supply start and then it burned the four mosfet closest to the power inputs. do you know what those mosfet replacements are and is there anything else I need to look for before I replace them
Dude, you're killin' me. Horrible focusing, soldering iron tip has seen a better day, mount the FETs first - then solder the leads, overdriving that unboxed woofer, etc.. But hey, I guess it's better than it was. LOL
Here is a tip a bit out of the automotive line. If you enjoy listening to audio off your computer, amps normally used in a car work great. You use a discrete DAC (digital to analog converter) for your volume control (you can get by using your computer DAC,they all have one) and some unpowered bookshelf speakers. You can find good 2 channel amps in a lot of pawn shops,they make a great addition to your desktop computer system. I am using a Rockford/Fosgate P4002 that I picked up real cheap,happy as a clam. The amp section in a amp designed for a car usually have higher quality parts than a home audio amp (OK up to a point) you are not paying for features you do not need (like a receiver). I use high capacity dry cell battery intended for an ATV and keep it charged off a 12v rail from my computers power supply. It is possible to wire in a sub if you get a speaker level sub to parallel off your speaker channels,works great and is a heck of a lot cheaper. It is pretty impressive when you see the quality of construction when you compare a car amp and a low level home audio amp.All these amps are just waiting on the shelf in your neighborhood pawn shop,make an offer,they work great at home.
I have a JL Audio 500/1 that's not powering on, no green power light or a fail light is coming on. I'm going to trouble shoot the connections, but if it's the amp, can you fix?
hello boss, i have a BRX3016.1D BRUTUS AMPLIFIE that is blowing my main fuse when turn on, am trying to fix it, do you know what i can look for are have any idea what i should look for, it sounds like transistors
hello I wanted to ask if you got some mtx 81000d amp need the componewntes saver that yeva ie codes are split and I do not see anything so I buy saver thanks greetings
Sir accidentally i connected -ve wire of battrey in the +ve side of amplifier and +ve side into -ve terminal and sparking got placed after that when i reverse the connection my amplifier still not working neither the fuse is blown nither the protector mode on it just. Showing sparking and heats the wire when i touch the wires to the terminal, then i checked it with multi metere and it shows the +ve and -ve terminal of amplifier is shorted can you please suggest which thing of amplifier is blown up??
only one of two speaker exits work on my 1600 amp can I plug both my subwoofers on the same exit-terminal(I don't know wats the correct term)or is it easy to fix???...
How come you didn't use any heat sink thermal compound between the new Fet and the existing thermal tape. Whenever you disturb the original interface compound has to be used. It will not transfer heat efficiently.
Hi I have a 2000 watt lanzar vibe amp and im having problems with it idk whats wrong I wake up in the morning to go to work my amp didn't come on so I checked the fues up under the hood and ir was popped so I put wire around the fuse and now the fuse to my amp popped so I put wire around them fuses and put them back into the amp so when I did I harried up and took them back out cuz i started to smell something can you plz tell me why it keeps popping my fuses
hey bro I have a amplifier that's in protection mode the power light won't even come on it's in protection mode as soon as I cut it on do you think it could be fixed
hey guys i have a amp and almost all the eq settings on the amp are rubber an there down to pretty much plastic with nothing to grab onto, what could i use to be able to move these
I have an Orion xtr pro2400 amp with two 12" alumapro alchemy Rx... the subs are making a non stop bumping noise while the stereo is on. What might cause this to happen
I have a mtx audio terminator amplifier thats rated at 251 and i put 250 watts for subs( 2 100 w and 1 50w) and it would turn off after very little bass now i cant get it to turn on at all. Anything you can think of that could cause it to stay in protect permanantly? Thanks
It is about the impedance and wiring your subs accordingly! The excessive heat is caused by too low of an impedance! Remember 8+8 ohm equals 4 ohm and 4+4 equals 2 ohm! Average amps will only handle 4 ohms bridged mono and 2 ohms bridged stereo. I take it this was a two channel amp! Obviously the amp is burnt and perhaps you could just opt for a cost effective mono class d at around $130-$150 you can get a mtx mono amp, if you need 1 ohm then they still make class d able to handle such impedance!
I have a Digital Designs M2C AMPLIFIER that I bought used 2 years ago. When it arrived in the mail, the RCA inputs were damaged. I desoldered them and replaced them with the RCA inputs from the master slave link side. I eliminated the inputs for the master slave link side. When I powered the amplifier on it turned on but no signal to the subwoofer. I removed the bottom cover and looked at the components and nothing looks like it's burnt. Could this be an easy fix? Please advise.
Hello, I have an amplifier and it doesnt work. Its lights are ok. Everytime I turn it on with the subwoofer connected 2 small components situated next to each other named C4467 and A1694 get hot. The speakers work fine because I connected them with my house Amp. If I change channel to my subwoofer then another set of these components gets hot equally. Moreover if I coonect only the speakers without the sub then it gets hot but slower. PLEASE help me...!
Hello sir, good work with your amp repair. Just wondering, off the top of your head you have any suggestions as to why 1 or maybe 2 of the mosfets in my orions xtr2500 amp are getting hot (just over being able to keep your finger on it) The amp still works fine, as far as I can tell but just that one or two mosfet gets hot just by turning it on, even if the speaker wires and rca's aren't even pluged in. Just hoping you could point me in the right direction. Thank you!
My amp is doing the same thing. One small MOSFET gets really hot. However I'm getting no audio output from the amp at all. All other MOSFETs seem to have 30volts to them. Any ideas?
Just got a box with a sub and a amp combine and try to turn it on and nothing the power light goes on and off so i pull the amp apart and one of the fets are burn i try to look for them around but i cant find them maybe looking on the wtong place ?
Hey I have a 1200 Brutus hifonics bxi 1206d and I wanted to know why does my amp keep turning of when I turn up the volume from my stereo and it starts to make this annoying sound when I have my speaker connected and if I have my amp on low bass it still turns of can you give me some advise to what the problem is thanks
Sounds like your speakers are improperly wired, and your impedance is off. Your more than likely pulling a lower ohm load on your amp than it's capable of. Check the ohm rating and number of Voice Coil each speaker has. Then check what ohm levels your amplifier is capable of being stable at. Crutchfield has a shit tonne of wiring diagrams to so you the proper way to wire it up. If your pulling 1ohm from an amp that's only 2-8ohm stable, then it will cause the problems your experiencing, and will likely end up frying your amp. Hope this helps.
Great channel love ur videos I have a Sony I'm having trouble fixing I replaced all the power supply fets with genuine Fairchild fets I need to check drivers I guess I'm a novice the amp powers on but has no sound
Hi I have legacy car amplifier and the rear connecters red and Waite is broken the plastic on rear I try to open and I break the metal go on the back can you please let me know if can be fix thank you very much
dude so my problem is dif when i hook everything up the light wont come on i know all the conection are good cus the other amp on those cons work just fine
alot of the time you can put a multimeter on an outside leg and the middle and do the same two down the line and see if the voltages are close together, you need to do this for the opposite side of the fets outer leg too
look at the colored bands on the resistor, then google resistor color bands to find out what value the resistor is. if its burned and you cant see the colors, look to see if there is a corrosponding resistor in the opposite channel, and get the value from that one. there may be something else that caused the resistor to fry though, so you may replace it, only for it to blow again.
Rick can you repair my JL audio 750.1 HD? There’s no sound output but everything lights up fine. I got ripped off on Craigslist paid $200 and found out it doesn’t work.
What? That amp is capable of 4000W at 2 ohm? I used to install car audio in the late 90s and an amp that size would generally be 150-300W mono. Orion Red, Precision Power and Phoenix Gold amps come to mind. A PPS amp @1000W was like 4 ft long. Have amplifiers changed that much in 25 yrs?
Sir i have rockmars 3000watt 4 channel amplifire when I gave battery current it on for some time but immediately its p55nf06 transistor dead I replaced that transistor but after that same process again kindly help me sir what should i do?
Hey rick, great video btw, but I have a 1200 watt sony xplod 2 channel stereo that will turn on and the green light will be on as well however no sound will be put out. I have opened it up and with a dmm tested the caps and they seem fine, any thoughts or suggestions?
Email me if you still need help. Skinnman33@Yahoo.com I have a small business repairing car audio. Have over 15 years experience. I am all over the internet for amp repair.
hey rick, i have a situation with my ma audio hk10ka. i've tested several amps with my pyramid power supply and after turning off the power supply, the green power light will extinguish immediately. Not the case with my ma audio, the green power light on the power supply stays on, as if the amp is feeding power back to the power supply. The amp hasn't powered on yet, it has only flickered a few times but nothing solid. There are a few speaker outputs missing cuz i believe it's been dropped but the pcb is fine, i have another speaker output rail to solder to it i was able to salvage from an ma audio 802sx. The last owner also says that when he would connect power to it, it would only blow fuse, my power supply protects for about 1 minute then comes out of protect and green light is on. Any idea what could be causing my problem and how much would you charge to inspect the amp? thanks
I've got an update..turns out my power supply is bad cuz it was protecting with another amp. I connected the amp to my battery charger and it powered up fine. I do have another problem I will get on vid and see if you can help me on it. Thanks
i posted a link to a vid i made earlier of a problem i'm having with the amp i was asking you about before. The link is in the same thread on youtube where i first starting talking with you. hope you can help..thanks
I have an old Orion XTR 2250 I bought at a garage sale for $10. Every capacitor inside is broken off at the solders. Any idea what caused them all to break like that and is it worth repairing? I knew something was wrong when I bought it because I could hear them rolling around inside. But for $10, I thought what the hell and bought it hoping to repair it.
So the person before could have had a short or crossed wires when power it on and blew the amp best bet is to see if you want the amp as the older ones are still better IMO but you would need to contact a repair shop and get an estimate
Just wondering why your using 16gauge wire for power and ground? If its 1500rms your wire just be 0 gauge and bigger. Of course its not making much sound with the littel wires.
RickTEG okay, jw. I have a jl audio amp that isent working. Iv took it apart nd dident see nothing wrong. Im not an expert but it looked fine. All my wires were good. They power my other amp but this one turns on. Just makes no sound. Got any idea of why its doing that?
Frankie james I would disconnect all the speakers first and do one channel at a time if not you will have to look to th output side check your RCAs too
to me..the easiest way to replace the transistor is to cut the old one off about half way down the legs....screw the new one down...then match the legs up with the legs on the circuit board..and solder it back..then cut off the excess...what do you all think of that???? I do this on computer mother boards, (laptops) with the power jack...I never unsolder the jack from the board, you will burn it up...cut the legs off...and solder the new one on top of the old legs...and cut off the excess...
Good job with what you had to work with Rick. I wonder what all these fucking pros are doing here watching your video, if they already know how to do it so much better. To each his own. If it works for you, then do it. Fuck these haters.
16:00 Not the best way to produce a reliable solder joint. Better to heat each clad with an iron and use a vacuum desoldering tool. Heating up the MOSFET to that high temperature just ensured that it will have an early demise, if it works at all.
No kidding! I repair caps and those with pulling the board and heating the pin hole up and pushing the wire through via the other side until it secured in and adding solder if needed.
Rookie soldering technique, wanted to scream. Try using a better iron and a solder sucker, you wont need the hot air gun. Also, maybe you might try TESTING THE AMP WITH A METER before powering up and frying your brand new FETs. If you don't know what to test, YOU SHOULDN'T BE FIXING AMPS!
Dude your beyond amature man anyone knows u cant use random fets in conjunction with others when they are produced they are done in lots, batches this is y there are other numbers on the ic these are date of production and lot numbers and with every group made tolerances vary and when u use multiple tolerances they fight each other and I promise you that "amplifier repair" as u called it lasted a week at most if anyone watching this wants to learn from a man who knows his shit look into "barevids" sam knows what he is doing
In my mind his vision is that blurry .type of pov fp . Hell since when did "fets" have a expiration dates ? Under voltage is the real killer here? #transistorslifesmatter
RickTheElectronicGuy the amp is a Alpine MRD-M301. It powers on and all functions well but i have now sound? any suggestions? I love this amp i don't want it to die but i dont want to spend heeps to having it going
sorry to be so off topic but does anybody know a way to get back into an Instagram account..? I stupidly forgot the login password. I would appreciate any help you can offer me.
@Khalil Jedidiah Thanks so much for your reply. I got to the site thru google and Im in the hacking process now. Looks like it's gonna take a while so I will get back to you later with my results.
may be that you arent getting enough juice from your cars electrical system. this will cause the amp to clip and overheat, and not put out the power its rated for. make sure your power and ground wires are at least 0 gauge for that many watts, but bigger would be better. a bigger battery and possibly a higher amp alternator will definately help.
Dear sir i hope you are fine i have a rock mars car amp model # RM-AF 4600 when i m give battery current its on after some time its p55nf06 transistor dead I replaced that transistor but again same process kindly help me
I got a 10,000 watt earth quake amp 1 channel class d, series j in protection mode with no speakers or RCA cables plugged in worked nice don't know what happened 1600$ amp ?????

alot of the time you can put a multimeter on an outside leg and the middle and do the same two down the line and see if the voltages are close together, you need to do this for the opposite side of the fets outer leg too
where low sound amplifier discard any problem tkuwn to believe?
Nice Job bro...thank.
Resistors fried , how do I know which ones to buy n replace ?
look at the colored bands on the resistor, then google resistor color bands to find out what value the resistor is. if its burned and you cant see the colors, look to see if there is a corrosponding resistor in the opposite channel, and get the value from that one. there may be something else that caused the resistor to fry though, so you may replace it, only for it to blow again.

Email me if you still need help. Skinnman33@Yahoo.com I have a small business repairing car audio. Have over 15 years experience. I am all over the internet for amp repair.
very cool work,,teach
this video helps me thank you for that. but daaamn please focus the camera already lol.
Rocking the legs like that can damage the board. Would have made more sende if you had clipped the legs off then removing the pins one by one
Was that the original fuse
awesome
hey rick, i have a situation with my ma audio hk10ka. i've tested several amps with my pyramid power supply and after turning off the power supply, the green power light will extinguish immediately. Not the case with my ma audio, the green power light on the power supply stays on, as if the amp is feeding power back to the power supply. The amp hasn't powered on yet, it has only flickered a few times but nothing solid. There are a few speaker outputs missing cuz i believe it's been dropped but the pcb is fine, i have another speaker output rail to solder to it i was able to salvage from an ma audio 802sx. The last owner also says that when he would connect power to it, it would only blow fuse, my power supply protects for about 1 minute then comes out of protect and green light is on. Any idea what could be causing my problem and how much would you charge to inspect the amp? thanks
could you take some pictures and a vid and post it on my website rickteg
sure, i'll have it on there tomorrow..thx..jeff
yup i will see what i can do for you
I've got an update..turns out my power supply is bad cuz it was protecting with another amp. I connected the amp to my battery charger and it powered up fine. I do have another problem I will get on vid and see if you can help me on it. Thanks
i posted a link to a vid i made earlier of a problem i'm having with the amp i was asking you about before. The link is in the same thread on youtube where i first starting talking with you. hope you can help..thanks
I have an old Orion XTR 2250 I bought at a garage sale for $10. Every capacitor inside is broken off at the solders. Any idea what caused them all to break like that and is it worth repairing? I knew something was wrong when I bought it because I could hear them rolling around inside. But for $10, I thought what the hell and bought it hoping to repair it.
So the person before could have had a short or crossed wires when power it on and blew the amp best bet is to see if you want the amp as the older ones are still better IMO but you would need to contact a repair shop and get an estimate
@@Rickteg thanks for the reply. I found a local repair shop that’s gonna fix it. I agree on the older amps being better
Just wondering why your using 16gauge wire for power and ground? If its 1500rms your wire just be 0 gauge and bigger. Of course its not making much sound with the littel wires.
8 guage for power and ground and was just for testing purposes
RickTEG okay, jw. I have a jl audio amp that isent working. Iv took it apart nd dident see nothing wrong. Im not an expert but it looked fine. All my wires were good. They power my other amp but this one turns on. Just makes no sound. Got any idea of why its doing that?
Frankie james I would disconnect all the speakers first and do one channel at a time if not you will have to look to th output side check your RCAs too

So what are the names of them?
Belo amplificador de car
Awesome video just what I needed. Sorry if I missed this part but once I have the model number where can I buy new fet transistors?
mouser electronics ebay
try frys electronics or ebay. or Amazon.
+RickTEG cheap ass camera
did it work?
to me..the easiest way to replace the transistor is to cut the old one off about half way down the legs....screw the new one down...then match the legs up with the legs on the circuit board..and solder it back..then cut off the excess...what do you all think of that???? I do this on computer mother boards, (laptops) with the power jack...I never unsolder the jack from the board, you will burn it up...cut the legs off...and solder the new one on top of the old legs...and cut off the excess...
Good good vid bt that blurry zoom made my head hurt lol
15 000 RMS my ass this would have A SHIT TONE OF TRANSISTORS TO BE CAPABLE OF THIS MUCH POWER and a big as fuck power supply
Good job with what you had to work with Rick. I wonder what all these fucking pros are doing here watching your video, if they already know how to do it so much better. To each his own. If it works for you, then do it. Fuck these haters.
16:00 Not the best way to produce a reliable solder joint. Better to heat each clad with an iron and use a vacuum desoldering tool. Heating up the MOSFET to that high temperature just ensured that it will have an early demise, if it works at all.
No kidding! I repair caps and those with pulling the board and heating the pin hole up and pushing the wire through via the other side until it secured in and adding solder if needed.
this is a DYI repair, we are trying to fix our a amp that belongs to us.
you need to replace parallel mosfet as well beacuse they need to be from same manufacturing series
Rookie soldering technique, wanted to scream. Try using a better iron and a solder sucker, you wont need the hot air gun. Also, maybe you might try TESTING THE AMP WITH A METER before powering up and frying your brand new FETs. If you don't know what to test, YOU SHOULDN'T BE FIXING AMPS!
+snysnd
hahahaha. dude i cried when i seen this. it was like a .... pure luck repair? i bet it fried in 10 mins again under load.
I have an sub zero ice spla 1000
It's in protection mode all the time please help me :(
Yes when i get one in
Dude your beyond amature man anyone knows u cant use random fets in conjunction with others when they are produced they are done in lots, batches this is y there are other numbers on the ic these are date of production and lot numbers and with every group made tolerances vary and when u use multiple tolerances they fight each other and I promise you that "amplifier repair" as u called it lasted a week at most if anyone watching this wants to learn from a man who knows his shit look into "barevids" sam knows what he is doing
I unscrewed one of my rca ports now I can't screw it back on any ideas
I just use a 100w iron...that has a chisel tip on it...that covers all three legs of the mosfets
you cannot allow the solder from one leg to touch another
no problem please subscribe
my amps come on but no sound what could it be
In my mind his vision is that blurry .type of pov fp . Hell since when did "fets" have a expiration dates ? Under voltage is the real killer here? #transistorslifesmatter
What the f... You are "soldering" a simple MOSFET with a huge heat gun?!?
I hope, i will never buy any used device, you have "repaired".
Peter Müller this was a joke repair just to see how many people would think it's great
I have a Alpine V12 amp i want to use but it dosent work. Where abouts do i start looking for the problem?
depends on whats wrong with it
RickTheElectronicGuy the amp is a Alpine MRD-M301. It powers on and all functions well but i have now sound? any suggestions? I love this amp i don't want it to die but i dont want to spend heeps to having it going
sure its the amp and not the rcas
RickTheElectronicGuy All good
Turns out this this amp has a disable mode for some reason and was turned on?
perfect! Could you possibly do one on how to fix a fried stereo deck?
sorry to be so off topic but does anybody know a way to get back into an Instagram account..?
I stupidly forgot the login password. I would appreciate any help you can offer me.
@Wesley Jericho instablaster :)
@Khalil Jedidiah Thanks so much for your reply. I got to the site thru google and Im in the hacking process now.
Looks like it's gonna take a while so I will get back to you later with my results.
@Khalil Jedidiah it worked and I actually got access to my account again. Im so happy!
Thanks so much you really help me out !
@Wesley Jericho happy to help xD
I have a 2400 watt hifonics Brutus it burned out because my music kept cutting off when I turned up the volume on the stereo
may be that you arent getting enough juice from your cars electrical system. this will cause the amp to clip and overheat, and not put out the power its rated for. make sure your power and ground wires are at least 0 gauge for that many watts, but bigger would be better. a bigger battery and possibly a higher amp alternator will definately help.

Dear sir i hope you are fine i have a rock mars car amp model # RM-AF 4600
when i m give battery current its on after some time its p55nf06 transistor
dead I replaced that transistor but again same process kindly help me
soft lips what's your O-scope measurements
RickTEG i have not facility of oscope measurement
RickTEG dear sir I don't have o scope measurement facility how can I contact you ans show show amplifire board
Yes newer ones with more capability
Amachewer!
Your shirt says Loveland on it, you in Ohio? I have an amp I need help with if so.
cool shrit
That was painful to watch. Try putting some flux and some solder on your iron and on the component.
sorry i been very busy at work please sign up for my forum for amplifier trouble shooting at rickteg dot com
I got a 10,000 watt earth quake amp 1 channel class d, series j in protection mode with no speakers or RCA cables plugged in worked nice don't know what happened 1600$ amp ?????
YIKES!!! Really? Do you work at one of those $1 install places? Hole-in-the-wall in a shady strip mall?
If the iron won't heat rapidly then clean the tip!
