Small mistake in the video: The yellow wire is constant power, and the red is ignition (i.e. turn on). Here is the power supply use to connect the boom box: ukposts.info/have/v-deo/ZZJpjJWWfn6D1Y0.html

I did this back in the late 70s with a Pioneer super tuner and a pair of 6x9s. It was my garage stereo for 35 years.

Great video! The yellow wire is constant on the head unit and the red is turn on. Keep up the great work 👌

Thank you AudioGuy for taking the time to explain out many of your builds. I am currently messing around with setting up some 15’s, 12’s and 10’s in a DIY backyard lawnmower shed stereo build, so that I (and the kids) can have some noticeable beats while playing in the backyard. This specific video assisted me with my power supply hurdle that I had with powering a Kicker KXA400.4 amp. (And NO, none of these speakers go over 200 rms.) But now, thanks to you, we’re all enjoying fun music outside.

DIY - Great channel and nice to meet you last week on 12 V Talk. Keep up the great work and I look forward to following your channel.

Tight budget people For the power supply you can use a power supply from a desktop p c , the wiring will be online for brand, etc, join all 12 volts together all ground together and not in use will be 5 volts depending on power supply, unless you want to hook up USB charging separate, etc... to turn the power supply on there is a trigger wire that can get rigger with a ground wire which a switch can be used in between it, or 5 volts trigger depending on power supply,

I hooked up a head unit to some small bookshelf speakers that came with a Panasonic mini hifi unit. It’s the best sound quality I’ve ever had for the money. For portability I connect it to my jump starter packs 12V 10A output. It came with a cable that just happened to be the right one to connect it to the power input socket. I used the same socket for power you did.

I'm working on FINALLY getting a test bench set up .man yours looks great!!!!

I use that same radio for home use. I hook it up to my bench power supply that is good up to 30V 10Amp. I have it connected to some cheap flea market 6x9's. I had a small wooden box laying around that was originally a shipping crate. I sealed it real good with caulk and used spill mats to deaden the wood so it wouldn't rattle. I cut the holes and screwed in the 6x9's. It sounds pretty good for what it is.

Very nicely done !! You explain everything very well. Thanks for sharing your thoughts and videos, Rodney

This is why i love pioneer head units, they have a built in powered subwoofer output meaning you can build the sub in to the unit where the main speakers are

Good stuff! Thanks for sharing.

Great, thanks for sharing!

I just run mine with a AGM car battery(no fumes), then put a trickle charger on it. Works great and no conversion confusion. It's all mounted in a box with a computer fan for cooling. I can take it to the lake or camping. Depending on battery it will last for days.

After watching your video you got me motivated to get back into the car audio. I would like to build a Raspberry Pi car audio home system, but I am struggling with trying to figure out how to wire the power to all the devices. The system would have the Raspberry Pi, a touch that connects to the Raspberry Pi, an equalizer, and a 360 watts amp. If you have the time and the disposition I would welcome any advice you may have to offer.

I've always wanted to make one of these, thank you

Great video 👍 just seen you on budget gem forum I support the community👌

That's cool! I listen to the radio more at home than I do in my car, but I have a better system in my car than in my house.

I made a setup in my garage with an old computer power supply. It outputs 12V and even has some 5V signals. The power supply is 350w so more than enough to run a headunit and a small 4 channel amp. Have pair of 6x9s on front and the 2 rear channels are bridged running an 8" Bazooka sub I had lying around.

Fantastic project 👍🥇

Where did you get the fuse block on the test bench?? And would that be OK to power a 1200 amp if it'd turned down. The 15 inch sub is only 200 was gonna run more speakers in my blazer but it never happened. So that big amp was running one speaker the installer turned the amp down so it wouldn't overpower the speaker

Those AMT’s are a great deal and sound fantastic

Great show see you next time

Great video series 👍

I actually thinking about this and seen this video 👍🏽

If you are searching for a high current power supply unit, a gaming desktop computer ATX power supplies are the way and only require switch be connected. Significantly cheaper than a standard PSU and with higher efficiency. Currently using a 850Watt PSU with an output of 12vDC @ 70Amps. My bedroom stereo system is a car stereo system including subwoofers.

Question? I hooked up my Kenwood car stereo to my power supply and every things good but can I hook this up to a home powered subwoofer using the good RCA cable? Please reply. Thanks.

I know this is an old video and im late to the party lol. But im considering doing this myself to build myself a custom bluetooth party speaker. Would it be possible to wire a small car amplifier inside the box to power to subwoofers seperately like you would in a car?

Great Information!!

I am going to have to live in a pretty tiny apartment and found some 50w speakers at my parents' place and wondered if I could use a car stereo to help me out? After all, those speakers are passive, so I would need some kind of amp - something a car stereo typically has. Are there any recommendations you have for a situation like this? Thanks!

PC Power Supplies are the most cheap way of getting that power. I had an older 450 watt power supply laying around and a friend asked, if I had something, to test his car audi amp on the bench. Some of those are power hungry monsters, but his only needed around 150 watts. The fan of the power supply was still running idle.

Good video. I have a system that runs a 1000 watt Amp to 2 15inch subs and a set of other speakers. I was using a deep cycle battery and just kept it charged. What kind of power supply would I need to replace the Battery?

What brands of car stereos have a feature that allows you to run car subwoofers without a external amplifier.

This video is very helpful but that shirt is the best man

Hey bro great video helped me out alot quick question tho i have a 12vdc 1amp adapter can that work to power the radio and alos how much watts can i get out of that 12v 1amp adapter

Can you use a 20 volt drill battery and use a step down converter to step the voltage down to 12 volts dc as a power supply to power a car stereo indoors

I had already done this at 12 with a 8track player and converter box from radio shack so I'm down with this

hello i have bluetooth radio i would like to cook up and 250watt amp what power supply should i get

After seeing some examples i conclude that a red optima battery and a wall-charger is the way to go,especially when i want the bench to handle 3000watts.

Can you please provide your link for the ferrules? The link you provided is for the cheap car radio. Thanks!

I had car audio in my room back in the 90's deck amp digital eq & 2 15in titans

I need to make test panel.amp is 60 amp 240 wat rms x2 bridged how much watt converter i need ?500w ok?plan run set 6.5 inch mids and tweeters and 1x 300rms 12 inch sub

So in order to power an amplifier you need the large 12v dc supply? Smaller one should be plenty of power to run just the headunit. Wouldnt your HU settings reset any time you disconnect the dc adapter from the wall?

Can you use a PC power supply for the AC/DC conversion? PC power supplies have 12volt rails and can go over 1500watts. Thanks

Pardon my ignorance but, are you using the 348w power supply to run the radio or are you using the "what looks like a lap top power supply" for the whole experiment?

Getting ready to order a power supply for my workbench for anything and everything car audio. Do you have any suggestions on a unit? I see multiple quality ones for under $100 and from what I am learning that's about right for needs.

Can you plug that ac to dc power supply directly into a home outlet? Or use a power supply like the one you're using?

Great video. Very informative and we'll articulated. I'm putting a stereo on my tool cart at work and have been trying to find a cheaper (space efficient and $$ efficient) way to power my head unit other than an expensive converter an I like the one you show. Also, if you don't mind; what was the song you had playing?

Can I use a 12v charger cord that plugs into the a house hold plug being 110v into an 1000w inverter to provide the needed amount of watts to my 1000w car amplifier so I can use my 1000w watt subwoofer in my home. I'd rather not have to buy a car battery or better yet a marine deep cycle which would cost me hundreds. OR Having the described application with the 12v battery of a 100amp being constantly charged as I use my subwoofer so I doesn't die. Seeing that I won't have an alternator to keep my battery charged while I use my car audio system in home. Any info would be great!!

This is a great way to run a low power system but if you are looking into a good system in your house. Get a power max inverter. They make all the way up to 120 amp ones. Made for RVs. And a lithium battery.

Great explanation, i have a question, i built a boom box with a radio, speakers using a pc power supply and i have a switch for On/Off the power but the memory of the channels won't get saved, what can i do to keep the memory always set. Do you have an email to send you the diagram i use. Need help with this. Thanks and great day.

Im using a 10” transmission line subwoofer along with my home theater. It was previously used in my car. Kindly suggest a method to properly power the amplifier at home. I have made a 12v 40A transformer for the 500w rms rockford amplifier but still im getting a lot of ground loop and distortions from subwoofer. Is it a good idea to use a car battery to power thr amp??

Can i use 12v 25 anorere power Supply???

Can a car audio passive cross over be used with a home speaker if the cross over frequencies are similar

Thanks for the informative video. Where did you get the car radio portion for that cheap?

Hello DIY Audio Guy! I have a quick question for you and I’m hoping you can solve my issue! I built a homemade Bluetooth sound system using car components such as a 4 channel amp for 4 6x9 speakers, and a mono amp powering a 12 inch subwoofer along with a car double din head unit and a 7 band equalizer. These are powered by three separate power supplies the same as shown In your video from Amazon. I have one 40a powering the 4 channel amp, one 50a powering the mono amp for the sub, and a 15a supply powering the equalizer and head unit they are all connected to the same extension cord and I believe everything is wired correctly. Now my problem is the static hissing noise when I have everything plugged in. Now this system sounds absolutely fantastic don’t get me wrong. It seems like everything is working great as it should. But the loud static sound when no music is playing coming through my speakers drives me crazy! I have tried wiring it differently, changing Rca cables…nothing seems to work. What would you suggest or recommend that I do differently?

How do we keep the memory saved like saved radios to be retained into car stereo powered by smps

Did you have any problem with static while using an auxiliary input?

Can 2 15 inch passive dj speakers be wired directly up to a car head unit or would the car head units built in amplifier not be powerful enough for them.

Cant you hook up your car subwoofer box and 6x9’s to a home amp that plugs into the wall?

Can I hook up speakers to my car radio, using the rca Jack's, the red and white Jack's in the back of my head unit

I used a 600w pc block power supply for mine and now see that you use the lighter laptop power supply, what is the little adaptor connector that you use? I am going to remake mine and it will be so much lighter with this.

I watched the video on UKposts by sundown audio unofficial and they ran a car amplifier on a 20 volt drill battery and what’s crazy is it handled it and it didn’t blow up but after watching the video the question is can car amplifiers really handle more than 12 volts of input voltage

What kind of power supply would i need to run a 1000watt amplifier in my home?

Are you using a typical car antenna in your house? Or, something that will do a better job of picking up stations? Is the antenna also inside the house?

Hi, can you design this setup(or make a video)but with a dual voicecoil subwoofer on the rear speakers? This would be great for a budget car install with a combo system in the doors an a passiv sub in the trunk. I think the key is to build a high efficiency subwoofer. Maybe 6th order Bandpass? PS: 15V DC supplys should also work for the 12V car stereo, so you can get a bit more power out of it. greetings from germany =)

Instead of using a power supply, would I be able to use an AGM or Lithium battery? If so, would I be able to keep a charger on the battery as I’m using it with a amplifier/head unit ???

Wouldn 't it be good to use some AlNiCo fullranges with a car radio? They are efficient, they don 't need a lot of power and, in a proper enclosure, they should have enough bass.

Is a much more powerful power supply required to power a car amplifier in bridged mode for running car subwoofers in your home.

Can a 10 inch speaker use a 5 inch passive radiator ?? I have a CompRT 10 Inch subwoofer kicker. But the space in my car is not enough for a big box please solve it

If I were to want to run car subwoofers inside a house and didn’t want to use a car amplifier to power them can a powered dj mixing console with a built in amplifier such as a rockville powered dj mixing console be used instead of a car amplifier

When you unplug the power supply from the outlet don't you lose all the settings you applied on the radio? I'm saying that because there is not any voltage for the internal memory so it can keep up storing things.

Hi, What is that spectrum analyzer hardware and software please?

If you power a car amplifier power supply that’s rated to handle 15 amps of current and the car amplifier draws 40 amps and the car amplifier doesn’t shut off and the car amplifier ends up working just fine will the capacitors inside the power supply explode like firecrackers if the wires are thick and don’t melt and catch fire

So would powering a sub be more efficient with like a plate amp?

Ok, so my radio has ONLY a black wire, other than the wires for the speakers, I can’t find a red or yellow wire at all. The radio is a factory radio from an 01 dodge Dakota, do I just use the black wire for the power source?

you're a CW Flash fan!

Yes I actually put a system into my camper...(don't judge me 😂) I had no issues with powering the amp or the head unit. The only issue I came across was the cheap dual Bluetooth radio I bought....having to wire the red,( ignition) and yellow, (constant/ memory) it was technically always on so would connect to my phone any time I was near it...even when turned off.

The link for the small adapter is a UKposts link, could I please get the link to the small power supply

what app is that on the phone thats being used as an RTA?

So what’s the link for the 12v power supply

How you will connect an amp for speakers and amp for subwoofer?

Hi again I solved my problem and haven't solved it so the good thing my radio is not faulty it works very good only when I use the USB CD or fm radio but when I plug the aux into my phone it only players music at max volume and its is very quiet and sound very bad so I don't know what to do

How is the power supply holding up?

So how big of a power supply converter do I need for 2 12s and 4 5x7s. I don’t understand the power conversion. The subs are around 500w rms combined and the 5x7s are like 350-400rms. Does that mean I need a converter that can do 1000w ?! The biggest one I can find on Amazon is like 350w…

See watching youtube at 3am does give you good ideas, I've got 2 JBL gti 1000watt 12inch subwoofers just been sitting about cheers.

hi friend . were i can buy the power amps please

So what if i wanted to put a car stereo in my garage permanently and i need 2500 watts peak power would i just buy a big power suply

In the past had done a few project with retro car stereo players

How do i hook up something with big subs? Something big power? Have a comp 6500rms half ohm stable mono block going to 2x15" 3000rms subs

What do you use for a antenna to use radio

Is that car stereo still working?

So I couldn’t use an 12v 2a plug ? Like from a router ?

How to pick the correct power supply for this MVH-S120UB

Your link took me to a 5v unit, not 12v?

I love it. Now if I can only build it (or buy it from someone else!)

How much for a build and sale it to me I’ll buy the items and you’ll it ??

Why not just hook uo to a 12 volt rechargeable battery or small car battery jump starter?

how much watts can a 12v radio support?

What's the name of the song?
