I have a question when i connect the power wire to my amp it sparks and when i unscrew the wire it sparks again , is the amp damage? how do i find the problem and fix it
@warthhoh its not uncoomom for the power terminal to spark slightly when connected. Many Amps use switching PSU which have capacitors that charge when power is connected or when the amp is 'ON' causing an in rush of current. If the amp uses a power remote, turn it off before connecting/disconnecting power If the sparks are big, like shorting a car battery, the amp does have a problem. Remove the cover and look for burned components. -MrFixit

ey men i have a ample amp 600 watts the mosfet resistor were burn out i replace them. it turn on and sound cam out but it lasted like 2mins when it died and smoke came out and i check they were the mosfet again i replace them again but it didnt turn on, this time it turn on a second and goes off the red light goes on but rapidly goes out. HELP ME SEND ME SOME SUGESTIONS HMENDEZ86@HOTMAIL.COM
@956mendez86 it doesn't help not knowing what brand & model amplififer you're talking about. By not checking to find the cause of the first component failure before replacing it. Are you sure the replacement are the same as the old one? -MrFixit
@ESRepair the amp model is (AMPLE EXONIC 270) 360 WATTS MAX. i take out all the mosfet out of the board and turn it on with out any mosfet install and gives me red light again. i check every single detail and nothing seem to be burn or broken
@956mendez86 The MOSFETs are the primary components used in the power supply. The power supply isn't of the regular kind and can only be diagnosed by someone who understands "Switching" power supplies. The MOSFETs are used due to low-resistance 'ON' state, high-resistance 'OFF' state, ampere capacity, and the fast-switching speed. These devices are very sensitive to static electricity. They are either P-channel or N-Channel. -MrFixit
@ESRepair what you should think i do, your best recomendations. i should make a video of it to show how is malfunctioning. IRFZ44N is p channel or n channel
great video, helped me understand the internals of an amp, can you tell me if theres anyway i can hook a factory amp to a sub? i have a mach 460 amp from a mustang and i'd like to have an extra low powered amp to hook to a sub, but since its a stock amp, it only has quick connect clips. i know for sure it is a 2 channel amp because it put 85 rms watts to 2 5 x 7's, is there anyway i can fix this amp up and hook it up without the stock wiring harness? or should i just keep it for parts? thanks

Hello bud it's me again I got a pioneer 760 watt amp 2 channel but at low volume it works fine but once I crank it up it cuts off the sound from the subs and it stays cut off until I reset the radio?
@Greenmonoluche Should check speaker connections. Also check the speaker's impeadance (ohm) is NOT less than Amps minimum requirement. To start. -MrFixit
I have kenwood kac7202 amp comes on fan comes on but no sound to sub any more got new RCA's speaker wire still no sound looked in the amp nothing seem to be burned out watched a few videos on how to test MOSFET nd transistor but not to sure what to do any solution
my amp has like the same problem, so if i poked the stuff and somethign is hot it might be the problem? how else could i fix it too, cuase if its something small i dont wanna take it to a shop and most likly be over charged
@ESrepair well thanks any ways but I already junked the amp.just goin to mount another amp in the sub itself but I really appreciate everything and next time I'll remember to connect the ground first thanks
@ES repair well I'm not really technology inclined but I checked ground wire nothing was burned or blown but her let me tell u its says batt on the left side u know were the wires go on the amp then right next to it says GND="ground" right then next to that says p.con which is radio remote. So my batt and p.con are already connected I connect my ground but when I do that it sparks and blows my fuse so IDK
@Greenmonoluche The connections are correct , however, the ground is always the first wire connected, then the BATT +, then P.Con (aka remote). By connecting the ground last, may have damaged the unit (page 5 in the manual for KSC-WA801). Never connect the ground last. -MrFixit.
@ESrepair hi can I ask sumthing I have a kenwood bazooka u know the ones with little built in amps and for some reason when I connect power to it then the ground the grounds getting power cuz i checked it with a tester so if u can help me out the model is a KSC-WA801 thanks
@Greenmonoluche There are two grounds one for the power (-) and one that is a Physical Ground (case). There should be no power going thru the physical ground. If reading Voltage from the ground (-) terminal on the amp to the battery's '-' post, you have whats called an "Open Ground". power should only flow thru the '+' and '-' cables/wires. check the ground cable. -MrFixit
i have a vibrant amp and everything turns on but there is no signal going through the amp??I tried everything possible, and even took into a shop and there's still no signal....Can you help me??
@EJ0245 Can you give me the model of your amplifier in question? Sometimes it can be a bad switch or the internal power supply isnt functioning properly, possibly a bad ground. You can use a Tone Generator to help trace signal degradation. I will make plans to show this process. It helps to determine where the signals are lost which can be a result of a bad board connection or a bad transistor (the actual Amplifier component). -MrFixit
I have a 300 watt Jensen amp and it dosent want to get power I've opened it and theres minuend smell or anything and I hooked it up good and it has nothing missing in the inside but I would like to get it working if you could please help me out
@214dallas931 Some AMPs have an internal fuse that may have blown. If the amp has a REMOTE connection, be sure it gets 12VDC to turn it on. You can trace the positive power using a voltmeter to find the dead spot in the amp. Common problems are a fuse, seperated board wire trace, no power to remote terminal, faulty internal power supply. -MrFixit
@bustablake92 The protection Dioide's function is to short the fuse to blow when the power cables are connected in reversed polarity to prevent further damage to the amplifier. The amplifier has an internal problem. With the problem you're describing, it sounds like the power suppy inside is shorted. Not much you can do to repair it yourself. A shop would need to look at it. -MrFixit
I have an 800w and a 640w kenwood amplifiers in my car stereo and it used to work swell, then while i would play my sound system it would short out and come back in then short out again and would keep doing it as i played it, now as soon as i turn my car on even if the music lvl is at 0 the fuses still pop immediate to when i turn my key for battery power, could it be the polarity check like u stated in the video? or could it be something else. Cuz my step father plugged it up to a
hey i got an 1800 watt amp an for some reason when i turn on my car the lights go on but then they dim an wont turn on :/ do you know what my problem can be? i checked my wires and they look fine :/
@madmkila1 Does the lights react the same way when amp power cables are disconnected? If not, then something may be wrong with the amp. If they do you should have the Alternator and the electrical system.checked. High powered amps can overload the alternater burning it up. If the amp draws excessive amount of current, the alternater will overload because its ampere capacity exceeded its limits. You can check to c if the electrical system has significant amount of AC, this bad. -MrFixit
Hmm. in finland we do not use word "remote" for that wiring. For us, remote is more like remote controller or such with a cable. We use word as "heräte" which is something like stimulus on english. That cable just gives a singal automatically to the amp knows when to shut off so it won't stay power on when car and audio is shutten off.
what kinda of power source is that just a standard inverter or what im looking to get into repairing amps but i was using a car battery before .. if so what kind
@MtxBeatsAllDay The power supply is a standard linear 120VAC to 12VDC 10 ampere. You can also use "switching" power supplies as well. There more compact and light wieght compared to linear power supplies. Iinear power supplies are easier to build your own. Inverters are a diffent type of power supply.
@MtxBeatsAllDay or cmputer power supply... if there is any trouble on your car amplifier... specially on the power supply section or smps section... it automatically shut down... so it could not do any further damage to the amp,,
@johnziebass yes, that's a good idea too. Their ampere rating is much higher than linear power supplies and not that expensive. Plus u have a wide range of voltages from 3.3VDC (orange wires) to 12VDC (yellow wire). Just need to modify the connectors to suit your needs. The amp may not draw enough power to force a shutdown but still cause damage a fuse is recommended between amp and Power supply. -MrFixit
@gamer1337omg I know. Technology has become cheaper compared to 20 years ago, however, some repairs are still cheaper than buying a new amplifier. -MrFixit
@88DJdan First check for blown fuses. Check all power connections. you can used a volt meter to check that power is getting to the amp. ensure the REMOTE terminal is also getting 12V. Bad connections will prevent the amp from turning on. If all checks good, there's something wrong with the switching power supply inside the amp. These types of power supplies are not easy to repair w/o a good understanding of how they function. Check to see if any components are getting hot. -MrFixit
@ESRepair Hi i'm having a problem with an amplifier thats built in to my polk audio tower speaker for my 2 8" subs it's max out put is 100W at 4Ohm it seems to have no volume but very little sound is comming from the woofers i checked the volume pot to see if that was the problem but it's working fine any suggestions what i could look at next the power light does come on when pluged in and it has low level and high level inputs and niether make a diffrence could it be my capacitors?
@1998tiburonse Some amplifiers have a bypass switch that is either manual or electronic. Check for the switch is turned off. Electronic versions will automaticly switch to bypass when power is turned off. Capicators can b used in 2 ways. When used in the power supply it filters fluctuations in the voltage. When connected in series with speakers the capacitor blocks BASS sounds from passing thru. If no change in volume between amp on or off, then something wrong with amp. -MrFixit
@1998tiburonse Also, if the amp uses a switching power supply like the one in my video, check the large capacitors are not damaged. Check for loose or bad connections. -MrFixit
@joquel12345 Unplug everything to the AMP except power & remote (if used). Turn on the amp. If the amp is still in protect mode, then something is wrong internally. Do not ground the case. The only grounding should be through the '-' negative terminal of the amp. If the amp doesn't enter protect mode after turning on the amp, check the input and speaker output wiring. Frayed and piched wires can cause the amp to enter protect mode. -MrFixit
Some amps have reverse polarity protection circuits built in them or sometimes a fuse might blow to protect it. Older fosgate amps don't have any fusing protection built into so if you reversed the polarity your f*cked lol. But that's why they have filter capacitors there.
@jinx1550 Yes, if you hook the battery's positive to the negative terminal on the amplifier and the battery's negative to positive terminal on the amplifier, it's called reversed polarity. This will damage the amplifier. Some manufactures incorporate a diode, as shown in the video, to minimize damage to the amp if such event occurs. During the event the diode will cause a 'short' circuit that in turn pops a fuse. The diode would then need replaced and wire traces on the board mended. -MrFixit
@ESRepair ok thank you! im jus looking for some ideas beacuse my ampifier is turning on an it has the green light on but it isnt playin no sound....wen i touch the speaker wires to the speaker output it makes a craking sound.this is a good quality amp.do you have any ideas what too do? i check an my capaciters and they arent blown an there are no burnts on the dash board.
@jinx1550 It has been years since I last worked on amplifiers. The crackling noise you hear can be caused by poor connections and/or frayed cables, poor grounding, etc. Be sure to use the correct input type (LINE or speaker level). If audio source doesn't provide LINE level, you can use a speaker to LINE converter. You may need to remove the cover to check for hot spots while amp is running idle. Thermal sensor or freeze spray can be used to spot hot components. -MrFixit
