Caution: laptop bricks are usually 19volts mostly 4.75 amps sometimes lower. (90w) An LED PSU is cheap and safer. Output voltage is adjustable 12v ~ 14 v and the output amperes is high. A 50 amp PSU is about 50usd at the amazon. (600w)
Also the wiring from that power supply you have is tiny, Normally only AC voltage is referred to as Live and neutral neutral not DC voltage, that would positive and negative or ground. I forgot to mention that atx power supplies have a lot of wires that deliver the 12 volts, so I connected them all together and ran them to binding post that are connected to the case, I did that for all the rails even the power supply turn on lead so it would be easy to use the power supply turn on, also that means I get all the current needed from the PSU and also I can use all the power supply rails all at the same time if needed. Look up atx power supply mod for bench top power supply use.
I was using an 800 watt ATX with APFC. Now I have built many 10,000 watt power supplies for amps and many other things, plus my PSUs also have variable voltage ouput.
It will work. But when you increase the volume it will shut down due to 5 amp limit. A 600 watt amp with one sub connected will draw approximately 20 amps at max volume with bass boost. Get a cheap regulated power supply with at least 30 amps.
There are many videos on how to run a car audio amp from a computer psu or laptop charger. It is clear these people have no understanding of basic electrical theory. For example a typical laptop charger supplies 19 volts at 3 or 4 amps, totally unsuitable to power a car amp. A car amp is designed to run off a 12 volt car battery that can deliver a high current. Firstly, running a car amp at 19 volts is likely to damage the amp. Secondly, even a small car amp will draw 15 amps or more at high volume. A high power amp requires even more current. All car amps require much higher current than any laptop psu can deliver. If you use an under powered psu the amp will probably work at low volume, but turn up the volume and the psu will either shut down or overheat and catch fire. Have your fire extinguisher handy.
*WARNING to anybody that is doing this WARNING!* Yes it will function plugin it in this way but a car amp usually requires 10-30 amps and these laptop chargers are only 1-2 amps. this can lead to distorted non clean power coming out of the amp possibly causing damage to the sub woofer or speakers. or even worse damging the amp but most amps have circuits to protect from this Please be cautious. *WARNING to anybody that is doing this WARNING!*
***** you wouldent be able to turn it up very loud but you have a high chance of hitting distortion and possibly blowing your subwoofers because when you cant give an amp enough power and it hits distortion it basicly heats up the speaker and burns the coils. so id be very careful but i do not recommend it. i really hope im helping and not sounding like 1 a smart ass or 2 your not understanding me :)
***** because some amp lifers will amplifies what ever signal is being fed to them not crossing it over. so that means if you connect it to the main speaker out you will get a full range sound coming out of your subwoofer witch can lead to distortion witch once again kills speakers in genral and you cant drive as much power as in bass power if you are trying to push the full range though them and not just below 100-80 hertz is usaly where subs go below.
I tried this with a xbox 360 PSU, the smallest one 150w 12a. With my two smaller amps it works fine, but when I want to try my bigger amp JL Audio JD1000.1, it instantly gives a red light on the PSU. Is it going in protection mode or something, because of too much power?
I recomend this for only 1200w amp and only one subwoofer , if its more then it will be too much power for the battery charger if you want something better , get a Xbox 360 or one power box it works very well
It's can show the light Power but can't run with speaker because 2A can't supply for car subwoofer amplifier it's need 30A up for full power, please noted 👌
Using a laptop charger is probably not the best idea, they output way higher voltage than an amp is designed for, also you need much higher current. When I rebuild, modify or custom build amps for customers, I use computer atx power supplies that come from the tower PC ones that is. They have 12 volt output which an amp runs on but much higher current. I am running my 2 12s with a 2kw monoblock amp with an atx, runs just fine, very clean bass, I also made a cap bank.
Ay I know this comment is 5y old but how many watts did you use for the atx power supply? I have a 1500 watt amp and a 1600w sub that i want to power with it
MATISTHERAT if you want more current you can actually wire multiple power supply's in parallel because this allows you to get more current and puts less stress on the wires so that you don't damage your car amplifier
just bought one of these power bricks from Amazon - I've had a 3 Amp car battery charger hooked up to a small 12V battery then to my 200 watt amplifier. It doesn't quite have enough juice for my setup. Thanks for making a video showing how my idea want completely foolish!
DeeJay HoldUpz OldSkooLCreW usually in DC lighter colors = + positive voltage and darker = - negative voltage. In your case, red would be your + and black is your - (a.k.a. ground or "GND").
And please, no offense my man, but if you didn't know which was which to begin with you need to learn more before you attempt this. Make sure your power supply is at rated voltage AND it's max current output is somewhere in the range of the amp's Watts you plan on using regularly. Please be safe and don't destroy your equipment!!
MATISTHERAT if I had a car CD player hook to the remote wire then ran that small wire from the 12 v to the remote would it be possible to run the CD palyer also
the higher amper-hours the better , yes? because i found pc charger with 12V and 8.5A. car battery has about 60A so 5A is very weak power source isn't it?
+Callum West and one more question :) if charger has 12V and 8.5A that means that i can power up 12*8.5=102W amplifier? because my amp has about 500w so i will get only 1/5 of overall power?
Sarunas Budvytis but to be technical for anyone who cares, there will likely be loss In power due to heat, possible resistance, corrosion, wrong size wires, fuse, or adapter....etc. but 102w is the theoretical (and possible) maximum :)
Vicky Jadhav I have the same issue. With voltmeter its ranging b/w 14.3v to 15.3v gradually scrolling but keeps within this range. Exact same question. Can i use it?
Does The little black wire that goes between the REM and the 12v need to be positive or negative? Also I will be using a ac to Dc converter what sides should the negative and positive go on?
technically it's a postive wire, so he used the wrong wire color, and the laptop DC is underpowered for most car amps, 12v laptops are typically 50W maps, rarely above 80w, i.e. 12V *6Amps = 72V
I used a 19.5v DC charger to power my amp, I wasn’t paying attention and as soon as I plugged it in it started smoking, I put the old 12v one in and all it does now is turn on, it doesn’t work with any speakers, so yeah, rip Amp
(WARNING): I recommend pc power supplys since they give power in a smoother way and have much more amps and barely overheat/Laptop Charger is weaker give horrible voltage in high volumes but OVERHEATS CRAZY AT THE POIN OF POPING A CAPACITOR LIKE WHAT HAPPENED TP MY OLD LAPTOP CHARGER(but you can do at your own risk but yeah really recommend pc power supply)
roki buča Xbox 360 power bricks or a computer power supply is for car amplifiers that are under 1000 watts for car amplifiers that are 1000 watts or higher you have to either wire multiple Xbox 360 power bricks or multiple computer power supply's in parallel or use a car battery instead
+Callum West that's why a pc psu is better but its ugly until psu's get smaller and safer for use out of the pc. Also i was thinking, does any car amp come with fan cooling yet as cooling amplifiers as they are running can trick the amp into not requiring more voltage when increasing the volume, electricity is a weird one sometimes as no one ever thinks it takes power to regulate and drop power too.. Great video, i always thought a laptop charger would work but never tried or needed to as i have a few active pro dj speakers, but for my passives i was thinking to have a car amp mounted to each one and make them independent of a amp source and also allow daisy-chaining when self mounted amp not in use, i would add a switch for this so its either external power or internal as i don't want to send power back to any adapters..
+Callum West I tried using a 12v and 7.2Ah(ampere-hour) battery to a 1000w car power amp. sounds nice n smooth but moment later smoke comin out and my amp f***d up! can u please explain what the h*** happened...

Very well said, I am an electronic engineer and can vouch for what this man has said.
thankyou bro you solve my problem easily love you
Thanks for the first minute, i got it working 👍🤙
great job man
How do u match charger for your amp? Your charger is still alive, it wasn't burn yet, Does its fill the requirement of watts of the amp?
Will it work on a 4 channel amp
Thanks, Callum.
Is this run on 12v dc adapter??
keep in mind that not all laptop chargers are 12v. not to mention the low power output of a power supply like that.
Exactly mines 240v Toshiba 😂
that's impossible. you were probably looking at the input voltage, you should be looking at the output voltage.
Can it work with set-up box adopter..??
How many ohms_amp should i get if my sub is wired to 8ohms?
Is it possible to run 2 laptop chargers together?
How many watts is the amplifier
Can I connect miss and subs together with an crossover??please make video..
What amplifier is that of watt ?
What type of plug do u have in the wall
PERFECT. RESPECT AUSSIE
Do i use anyother adapter instead of laptop charger Adapter??

Luke Hammer All car amps are 12v
Thank you sir!
I have a Sony car amplifier 1200w will it do ?
I recomend this for only 1200w amp and only one subwoofer , if its more then it will be too much power for the battery charger if you want something better , get a Xbox 360 or one power box it works very well
Or get a cheap 500w PSU!
Can it be ac instead of dc?
Question I only have a black and white wire ?
great idea
what black cable could it be
I LOVE YOU THANK YOU!!!!!
Thanks so much
What do i do if i only have one wire?
Brilliant!
Sir but laptop charger output 19-20v but our amp suport only 12v dc
this black cable must be or not +12V rem

Will a MacBook charger work
Makasih ....bos....bay indonesia...
my color is different + is white & one is open wire i guess its negative. So negative will go in GND ?
does the bass comes the same as it comes from a car battery ?
Nope

what if my laptop charger has a white wire inside of wire thats around it?

Anthony Volkman so instead of a laptop plug-in you are using a actual computer wire instead
I like your idea. It makes a lot of sense to do it that way instead. So I think that I'm going to try it and see how it works.
Ay I know this comment is 5y old but how many watts did you use for the atx power supply? I have a 1500 watt amp and a 1600w sub that i want to power with it
Batteries parallel 12v battery charger on 2 amps pound it all you want
that way works for little while with low watt amp it can't supply enough amps to run anything decent
your best option is to get an old psu from a computer and watch vids on connecting them that way

Callum West ohh cuz I did already but tha amp keeps flashing the lights idk y
My car system has a 100A fuse on it, this would RIP it real quick
I mean best ting to do I just buy a car battery
It works the opposite actually 😅 The power supply wouldn't be sufficient enough to power your amp 🤷🏻♂️
@@Flowshow88yes and no, having the amp drop in power will cause clipping, damaging the sub
Depends on the 🔊 speaker's 🔊!
