please guys use use thicker wires on car amps... this one's fuse says 30A so it will probably need about 20 amperes, those thin wires no way can support that. the amp either will shout down if you turn the volume up, or the wires will get hot and melt either way Bad. there's a reason why car audio installs use at least 10 AWG wires...
Wire gauge is dependent on two factors, amperage and length of run. In this video I am running a 12v 20amp power supply and running the power less than 1 foot. Based on those calculation, you only need 18ga wire. I am running 16 gauge. Now, if I were to run it at a typical length in a car, 20 feet, I would now need at least 8 gauge wire. You should always use a calculator to check to see what the least wire gauge you should use is. As you stated, if you do not, you could start a fire. Here is the calculator, I use. before I run any of my power wires: bulkwire.com/help/recommended-wire-gauge-calculator This will at least give people an idea of what wire to run. You can always run 1 gauge higher, just in case. Thank you for helping explain the importance of wire gauge when running power.
honestly I didn't know that wire gauge is dependent on wires length also, it's good to know but I still wouldn't use such thin wires to power a car amp. maybe it's just me wanting to be on the safe side. out of curiosity I might do a test with a thin and thicker wire, same length, playing a bassy song or even better a low freq sine wave, turn it up and see if the wire gets warm or not
That is a great idea. Just make sure you are running at least the minimum gauge wire. Mine never even got a hint of warm and I played it for hours afterwards, just to break in the sub a little. That was actually the first time I hooked the sub up. On a side note, I completely understand wanting to be safe. I would much rather be safe, then to burn something. I actually pinned your post, so that others know the importance of using the right gauge wire. Thanks again for bringing it up. You can never be too safe.
The reason your lights dim, is that you are creating a shortage in your electrical current. Basically, you are drawing so much electricity (when your bass hits it draws even more) that you do not have enough current for the rest of your components. If it were me, I'd turn down some of your gains. Unless you really need that much bass, you do not need your gains that high.
That's not the information needed to know if it will pressurize a room. However, any subwoofer, if it pressurizes a room too much, can crack a window.
Thank you! I bought one of those power supplies in your video description. I upgraded my old subwoofer set up and i wanted to use them as a sub set up in my house so this is perfect.
PERFECT VIDEO !!! I've been looking all day for a video for head unit to work as well as amp THANK YOUUU! life saver
Sweet..! Thanks..! I just saw your car stereo in the house video and actually asked about this in the comments... Thanks man..!
Closed Account you're welcome! Glad you enjoyed it.
Thank you for your detailed instructions you've provided.
I've been watching a lot of TH-cam instructional video's to slowly gain more knowledge about electronics & wiring to improve my knowledge of building electrical projects before I start my new project of building a home theatre systems that wire hopefully sound incredible for my own enjoyment of the love of music & movies.
I remember watching Hancock when it first come out at a friends place with a unbelievable home theatre system its unbeatable once you've had that experience.
your voice is very soothing..and a awesome video. i never thought i can find power supply with higher amp besides a computer psu.
Personally, I would run a computer PSU over that bench PSU any day. PC Power & Cooling make some of the most well regulated power supplies in the industry and they can be had reasonably cheap. An old school 500w ATX psu will have multiple 12v rails and one of the 5v rails can be used as the remote turn on source for the amp, or even one of the other 12v leads on the PSU.
Another thing about computer PSU's is that the power regulation is much more robust and the 12v rails on modern ATX PSU's are designed to operate at 12v continuously with very little variation. They also have fans which help the transformers stay cool under load.
Lastly, most current 600 watt (and above) ATX PSU's will have at least one 30-35 amp dedicated 12v rail which is more than you will ever need for a 400w DC amp, and if the PSU you choose has multiple 12v rails, they can be combined to proved the aggregate output across both rails. In other words, if you need 50 amps, you can combine the 35 amp 12v rail with a 15 amp 12v rail and have the power you need on tap.
Go for the ATX PSU.....
Thanks men you really helped
That kicker amp will draw way more than 20amps than that power supply has offer and u really need a 15volt powers supply cause the voltage will sag bad at 12 volts and clip the amp but its the right idea hes showing u so thumbs up for showing guys how to do it not bashin u brother just speaking from lessons learned
You can turn these up to 14.8 which is what I did. yes I agree 20 A is not enough especially for class ab amplifier. I went with a 40a
Great video. One question, what device did you cut the power plug from? Does this need any special load ratings?
I always thought a car stereo head unit would be choice for these homemade super ghetto blasters because you can use the fade front to back to split the volume between the high range tweeters and small speakers and the mid-range drivers so that you can control the blend with the head unit's fade controls on like a 4+1 channel amp. I also thought having an automatic extending and retracting radio antenna would be pretty slick too.
hi there
the video you made a couple mounths ago were you showed how to hook up speakers to a car stereo got me thinking about a few things. And one of them is how many speakers can you concet to the stereo. GREAT VIDEO!
greetings from Sweden!
Awesome! Glad it helped. The simplest answer is 6 (2 front speakers, 2 rears and 2 subwoofers) However, if you have external amps and the power for each one, you can hook up significantly more.
Best tutorial I have seen so far. Only thing missing is how to install a switch so that you can cut the power to the power supply.
The only problem with turning off the PSP is that many car stereos (especially older/vintage) will lose the memory settings, kind of a PITA to redo them.
Thanks for such a great video. I am a little confused though. Can't really see the power supply connections good. Looking at the link provided for the power supply, it looks like the power neutral ground are on the other side.
Hi, thanks for the video.
I have the same head unit haha
How do you connect AUX to external media player like Bluetooth?
in the manual it says using KCE-237b cable, do you buy that cable?
thanks again
Hey man what kind of power supply box would i need for a 1000watt rockford, 2 - 12inch rockford subs and a regular stereo??
How can I find the video on how you hooked the wires up to the regulated power supply
I have one power supply 12 7 amps I got this from led light
Is it necessary to connect the ground on amplifier?? Thanks my man..
Well said dude...
I just found and subd to this channel a couple hours ago. What are your thoughts on using an xbox360 power block to power an in home amp? If you happen to have on to test the and do the quick calculation to find out the average power it can put out/ how much RMS power it could push through an amp. Well I think you understand what I'm trying to say
CarJacks The Clown I'm glad to hear that. you can definitely use a Xbox 360 power supply if you have one on hand. The only issue is Xbox made 2 or 3 different power bricks depending on the 360. they ranged from 150 watts - 245 watts continuous power. I, unfortunately do not have one on hand to test it out. but I know you can get them relatively cheap.
Great how about the memory for the radio as the power goes off
Can u add sub if head unit does have rca out but dont have subwoofer setting?
Dude I was doing this back in the early 90's!
I have 40amp fuses. What power supply should I buy to power up whole serup?Is 40amp 12v enough?
Did you connect the yellow and red wire together?
Look for used server power supplies, they can be 750 to 1000 watts, and provide 50 to 70 amps!.
I wann plya sony xplod xm n1004 car amp is 15 ampere sufficient?
must all speakers have same oms and stuff
What cables from the car sterio did you connect black to the? Yellow to the? Red to the?
Okay, so my amp only has one set of rca Jack's. Running it off subwoofer rca in radio. With that being said, if I plugged all my speakers and subwoofer into the amp, would it blow my speakers because it only has subwoofer controls/power?
Is there any non car amp that can be used with a head unit? Or is there any way to modify the wires out of the head unit? My plan was to make a boom box using a head unit, speakers I built, and bluetooth 2.1 amplifier. The amp also has an aux in plug. It has the speaker outs with more than enough wattage. I cant be within 5 feet at full volume without ear plugs. But no way to connect the speaker wires from the head unit.
What if i want to use a car amplifier to power 4x 12" jbl home floor speakers and use my tascam home cd player as a head unit, is it possible?
do I have to use the blue for my remote or not
Ok wouldn't a 12 car battery typically power a whole system....idk I'm trying to figure out a power supply to test equipment and clutchfield suggest something closer to what a battery put out opposed to 250 watts ( this made me think...I was like does the amp make the stronger wattage.
OK here I have a major problem. Is it OK to connect a 5000 watt 1000 RMS car amp at home. Fuses are rated as 2x 25a on the amp . but the house outlet is only 15a -20a max . so is it OK to get a power supply rated at 60ah to connect in the house . so give some advice plz
Could you not just use a 120v AC to 12v DC converter? Then just cut the female adaptor off and wire positive and negative wires to the amp, then run the RCAs to a mixer?
hi again!
after hooking up 4 speakers to the stereo powerd by a 12 volt baterie it shorts out. Evrytime i turn up the volym it turns off then on again after a few seconds.
I wireed evrything with quick connects and some electrical tape.
Thank you
Are you sure the battery is charged? And or can send enough amperage? What kind of battery is it? Make sure none of your speaker wires are touching. What kind of speakers are they? It sounds like you either hooked it up wrong or are using speakers that the amp can't drive (ie check the Ohms). But honestly, it could be 100 different things. Without seeing it, I couldn't tell you for sure.
I did this but my stereo negative and positive wires are getting really hot? Do I need bigger gauge?
Can I use a 110/120V 15 Amp AC Power Cord to power a 110/120V AC to DC power supply that outputs 30 Amps?
Can this power supply be used as a battery charger ?
hello and thank you for the videos.
Please help me chose the right power supply for my setup.2 AMPLIFIERS OF 4 CHANNELS EACH @2 ohms 1000w RMS .
(Amplifier Audisystem HX series 175.4) 2 of them
Focal k2 krx 3 power system
dsp Zapco
Thanks in advance
Good thing about those "led" power supplies is that most of them have small potentiometer which can be used to adjust output voltage up to 13-14v, on pc power supplies you have to open them and mod them, after that you can just hope that it wont explode :D
Great point
turning up the volts on these has little effect really. On these, as u turn volts up the amperage goes down, and output wattage remains the same.
Yes, but most car amplifiers are rated at 14.4V which means you are gonna get a bit less power on 12V, my old sony amplifier does about 80w on 12V with psu dropping down to 11V but after i modded it to get 13.7V on output i get 100W so about 20% less on 12V vs 14V
Im sure amps circuits vary on tolerances, Just generally speaking tho, output is based on the amperage. On my old PG class D there no difference tween output at the speaker wires tween 12.5 and 15 volts the PS could do. My best results to date have come from using a server PS...12.9 volts but a decent 75amps. Keeping the ohm load within reason it has no problem with max RMS of 500 W @ 4 ohm.... and a whole lot cheaper than buying a PS with the voltage adjust feature.
Charles Hendricks Yes, depends on how good power supply inside amplifier is, some will drop rail voltage and clip the signal on higher power draw with less voltage on the input, thats why most people go for 14v or higher in their car, your might too, did you check it with oscope?
Wonders if there would be any benefit from putting a boost converter between the 12v supply and the amp to give it 14.4v.
Not really, except to run a little cooler. But you would lose some power at that cost. You'd be better off just getting a 14v power supply.
I thought it had to be on a pool table, and my felt is now shredded.
Alec Mason lol, that is hilarious. You win the Internet!
Thanks
Making comments like that my friend lets me know that their is no way u shod b messing around with wires
What guage wire are you using on that amp?
If you were to connect a car battery in parallel to your 12 volt power supply (+ to + and - to -) then you would increase your peak power if you had a large amp and lots of bass from a smaller power supply. I mean you can get power supplies of over a kilowatt but if you have an old car battery knocking around it seems like a good idea.
Tim Lewis capacitor seems like a better idea...
Actually that lil PS might not charge a battery. Best option and keeping it simple, get a beefier PS. Server power supplies give the most amps per $ if you buy them used.
Thanks for this. I do have a question. I apologize if this has already been answered. Is it possible to connect a car stereo to a home receiver, not a remote set of speakers. Basically MacGyver the head unit so that I can connect it to the home receiver with some RCA cables, similar to the way one connects a DVD or other component. I'd like to connect it to the AUX input. Thanks again.
Sure... U can use the RCA outs from a head unit and connect them to the inputs of your home receiver... just got to power up the HU with 12 -14 volt power supply.
Good vid, informative! Questionable music choice, haha.
Lol, thank you. It's good to know, not everyone enjoys the music ;)
What do I do if my amp is in protection mode?
How would I wire a switch between the radio and power source to act as an ignition?
You can add a switch to the red wire
I went to send you a private if my car amplifier has one 30 amperage fuse and my power supply is 30 amperage what will happen if I increase the volume to max and the bass is play hard what will happen will my amplifier will turn off
Nice video what's the link to the power supply
It's in the description of the video. :)
Do you know if I could use a power amplifier such as a peavey or a crown amp instead?
To run a subwoofer and speakers? Sure. Not to run a car amplifier or head unit though.
If i use a xbox 360 power supply what to do
HEADS UP YOU CAN GET USED HP SERVER PSUS ON EBAY FOR >$20 that put out 80 AMPS. LOOK UP HP POWER SUPPLY BREAKOUT BOARD IT WILL ADAPT OUTPUT FROM PROPRIETARY TO BARE WIRE!
can i use 12v 15A power supply to power up my 12V 15A 350 watt sony car amp ?
It'll probably work will probably get pretty hot. Look for used server power supplies on eBay like a dps-750rb.
I can make a boom box Mann thnks for information
Your Welcome! I'm glad I could help you!
can we skip head unit and use laptop or mobile to input the amp?
manoj Mahale yes
can i use 12v dc laptop charger to power 1600 power amp and car radio stereo using the same 12v dc
No...look at the Amperage rating of the 12v DC. Multiply amperage with 12 and you have the wattage.
Can i see where do you put the rca cables?
Miguel Arthur Desamito it shows at 6:25
I did that install but I have a power draw when any bass hits I only have a amp on the plug my head unit is on a separate power supply MTX 342 2 ch
Same as me bruhh , Ima try changing the sub wires for some bigger ones . Respond if u find a solution please
I added a car battery
Can I wire front speakers off the head unit if I only have a mono amp
U can. Typically a head unit is 50x4 (22x4 rms) if your speakers call for more power an amp will obviously give u more power
I live off grid and don't have access to a 110v power source unless I ran a generator. What I'd like to do is have the setup connected to a battery that is kept charged with solar panels. How would I accomplish that?
It'd be even better if I could connect a camera to a switch for security 😎
Can i use this connection permanantly.
rupesh bhate yes
so i was wondering can i use just the end of a extension cord if i dont have a 12 volt box...
No. Your amplifier and stereo all run off 12 volts. Your house supplies 110 volts. If you just used an extension cord, you would fry your electronics, as they would get 110 volts, which is well above their 12 volt operating range. You need to convert your 110 volt to 12 volts. Honestly, these 12v Regulated Power SUpplies are not that expensive (around $20-30).
Can I use my old laptop charger?
where did you get the power supply from?
Reid McDowell Ebay
Will a Xbox 360 power supply work?
Omg save the pool table 🙏🏻.........
lol, no kidding,at first i was like,"is that stuff sitting on a pool table?? ha ha ha
plz help me to reverse the idea..
i have home woofer with 2 speakers workes with AC power 220v # 12v~×2 - 2 amper i want to put it at my old version car cause i really like the sound of that speakers.. thank you
Mohamed Driouich Speakers typically aren't powered. They are a passive unit that hooks up to an amplifier. You can hook up your home speakers directly to your car stereo via speaker wire. Just unhook your front or rear speakers and hook up the wire to your home sdpwakers. If your speakers are powered (Have a built-in amplifier? You'd need a power inverter.
123Toid thank you for answer ..i need the power invertor to change from dc to ac ! how i can built the invertor for my subwoofer cause he works with ac power 220v and transformed to 12v~×2
so how i can transform 12v continue to 12v alternative
or 12v continue to 220v alternative ... thank you
Where did you get the power cable? The one that was stripped at the end?
You can get one here: amzn.to/3JG4AgG
Is there a way I can contact you like send you a pic of the wires from the power cord ?
@@Toid howd you get the Bluetooth to connect ? My stereo wont.
What i really want to learn is *how to connect subwoofer amplifier to **-car amplifier-** an amplifier without an Sub-Woofer output*
Do you have link for the psu?
thanks
what cable using for Rev
hasry hasmadie mohamad roslan I'm not sure what you're asking
so what wires do I need I'm so confused I have the head unit and sub. and do I need a 4 channel amp or could I use a mono amp and connect my speakers to it still? sorry I don't know much about audio. and my sub has a rms of 1600 watts and the amp I'm getting is going to put out 1600 watts so would that mean I need to get a 1600 watt power supply. and what speakers would i need to connect to this. PLEASE HELP
chris starkey what kind of sub do you have? Are you sure it's 1600 Watts at 4 Ohms? you can use a mono amp if you want. you just need a regulated power supply that's strong enough to power it
and what amp do you have
Can i see the rca cable pls
I don't have any pictures of it. But I detailed it from 6:20 to about 7:43.
Hello sir! Please tell me the current needed to 4 channel amp.
That all depends on the amplifier. Volts x Amps = Watts
123toid what model regulator is that? I'm trying to check the video but I can't really see the numbers on it.
Power supply? I put those links in my description, but here it is for you: amzn.to/2nOZWoZ
@@Toid sorry I didn't see the link I was on my phone appreciate it. Question I have everything hooked up and working but in-between songs their like a popping clicking sound any idea??
@@melito25 It's hard to say without hearing it. it may be a ground loop.
@@Toid thanks
you can also use a old computer power supply
7fishcody Great point! if you have one lying around, it's an easy way to do it.
I have two old power supplies laying around. The problem is WHY they are laying around. One came from a computer with a fried motherboard. The other one was a bestec power supply I replaced after 2 hard drive failures in two weeks. I wouldn't trust either PSU with anything expensive.
Server power supplies. The ones from data centers like a DPS 750 RB are highly reliable and can produce way more than necessary current for a car amplifier. Each one needs to be able to power all 15 of the 15000 RPM drives that are inside of a server plus the 4 CPUs in case it's Buddy (the redundant power supply) that it's working in tandem with fails. so they're extremely overpowered. . . you just have to Google how to hotwire them to turn them on and then figure out how to connect your power wires either to the posts or the tab contacts. I picked a 750 because it's got plenty of power and the fan on it is very quiet and it doesn't get hot on its own. I'd stay away from any of them that have a heat sticker or a "don't touch hot "sticker.
Did I miss something? I think I missed the step involved in setting up the aux input.
No. I didn't put that on the video, since my radio has an aux input on the back of it
Ok
I have a question, if anybody knows to answer I will be very pleased. Im planning to do the same thing, but has the mobile phone enough signal power to release the full potential of the amp? Because my amp is only 50x2 rms, and if the mobile phone signal is so weak, I wouldnt hear anything.
Thanks in advance.
❤
Could anyone tell me please what power supply would I use to power a 1200w amp and sub?
How to hook up a car stereo in your house? First you have to get the car inside your house. That can be a bit tricky! 😅
Figuring out big a power supply can’t be done measuring the power available at the output of the amp. Also, don’t be fooled by the rating they give to and amp. 500 watts is at 10% distortion, not clean. Car stereos use bogus specs to fool people into thinking your buying a better amp. Remember, at 1% distortion is when the signal coming from your amp is audibly distorted. Anything below 1% is relatively clean. Clean sound is what you want to listen to music playback. Also make sure it’s frequency range is as wide as possible. It should be 20Hz to 20KHZ. Anything less is only part of the signal, and you might be loosing a bit of your music. Back to the size of the power supply your going to need, there should be a power consumption spec. Add up that spec for all the components in your signal chain!
What kind of power supply is that?
It is a 12v Regulated power supply. This is the one I am using something similar to this one: www.ebay.com/itm/DC-Power-Supply-12V-0-5A-1A-2A-3A-5A-6A-8A-10A-12A-15A-20A-30A-Plug-Pigtail-lot-/401103056399?var=&hash=item5d639aee0f the 12v 20a
I have a 4 inch screen from a backup camera how can I power that in home and hook it up to a cctv camera always on no dvr no audio?
3:07 "first you are going to need to turn your car STEREO, (not amplifier) around..... :)
Should have just use rca to aux
Guys you can use a old Xbox 360 cord to power it
More detailed on connecting the wires would be really nice not just showing them completed. Otherwise thanks
I guess i need 1500w psu if my amp runs 1000 RMS
Trenton Earnest whatever your RMS is at 4 Ohms
Trenton if you look up the manual for your amplifier it will give you a current draw specifications you check that current draw against what power supply can provide. You could try two dps-750s In Parallel.. .
Wow, that’s a really groovy song..... 🤦🏼♂️ 😆
How much did you pay to build this
Most of this was stuff I already had. However, you can easily pick up an amp and head unit for around $20 each. The sub-woofer, I bought off parts express for $10. So it all depends on what you have.
why dont u skip that box and go with a 12v charger to it
Just don't use a Funky Pup subwoofer, your windows will blow out...
Amp looks like a whole Xbox 360
About the power supply. I think you got your facts wrong. It isn't 240watts. It's 240volts. Just wanted to put that out there
you know you can use a car 12volt car battery
sure you can, preferably more than one, and you'll need a way to keep them charged
It's not RMS it's how many amps between the car stereo in the amplifier getting 12 volts is easy getting enough amperage to keep up or even turn the system up is the hard part! RMS is the recommended power rating for the speaker and how much the amp or stereo can put out. 12 volts will turn on the amp and radio. But if the car radio is 20 amps and the amplifier is 40 amps you can't even turn it up without it shutting down.
All that job for nothing....get a Pioneer head unit...power it up from an old laptop power supply......in the menu turn the rear speakers from FULL to SW..(pioneers have an option which make them from 4x50 to 2x50 + 1x70)....connect the front speakers and the sub...enjoy the music
Easier to just get a car bat
