12v 12 volt 19v 19 volt 24v 24 volt Step Up Boost Converter - Розваги
Sounds a lot smoother with 24v
This was a very valuable video, thank you. I have a fair amount of uncertainty that comes from inexperience, this was a great step in the right direction for me.
I have so many of these little amps that my wife is thinking I am running an IT business.
Mini and nice modal
If your power supply is only 12V and 2A, then your max is 24 watts assuming 100% efficiency. Doubling volts cuts amps in half, so you end up having 24V and 1A. Volts x Amps = Watts.
wow ... i am so happy to find this video is the step up convertor capable of being installed in a car with a battery voltage of 12v 24A?...
i was thinking about it, i have a plan to make a subwofer with tpa3116, i think i need 24v power for a tpa3116 amplifier
If you're only getting 2 amps from voltage booster that tells you right there the most you'll get is 50 watts
Thank u sir with that informative video.
I have a toshiba mini soundbar subwoofer which is rated 40watts @8 ohms. Its a passive subwoofer gets its power from the amp installed in the soundbar.
I have tried this 100 watt mono sub amp and its working with a 4amp 19 volt power supply without a problem. I used audio 3.5 jack to input the stereo signals from my phone.
Now i cant figure out how to use signals from my car audio. The player does have a sub output but the input requires R.L.G. a set of three wires.
Also do i need a step up circuit in order to boost 12v of my car? It worked when i tested but it seemed a bit distorted at 12 i think.
Great Scott, thanks for the video! :) (BTTF... one of the best movies ever!)
I have a Klipsch Promedia 2.1 set that I blew the amp in. I tried to fix the amp by installing new fuses, but the fuses keep blowing, so there are other components that are damaged. Anyhow, I saved the set (Bought a Logitech z623 - lol which is booming with your video here. :) ) and was interested in putting the Klipsch sub in my truck. Would you know, and could you tell me what wires and such would be needed to do that? I suppose I need to run a power wire to the battery, through the firewall?
I just installed a new Sony stereo. It has an RCA jack in the back for subwoofer. I already ordered an RCA wire - 20 feet or so. I was going to just try to hook it up with that but i'm sure it's not enough power. I have a Sony DSX-B700 4x 55W. I don't need anything outrageous, just a little extra bass than the factory speakers put out. Which.. the factory speakers are pretty nice.
So cheap! But it looks so good with the subwoofer!
which power supply do you think would be best for this amp? 24v 4-5 amp?
or stay safe with 19 volts 3 amps? thanks
I just installed it but im only getting a hum noise. Im using 24v with a 200w power supply.
Sir can I use my step up converter from motorcycle to power small 24volts power amplifier?
Hi friend. I'm planning to run a 4ohm 100w subwoofer in my car with this amp. Can I get a clean bass without distortion with the available 12 v power supply? Will you recommend?
my subwoofer with same board is passing through higher frequency like 850hz ; any fix u aware of?
How useful did you find the crossover frequency control? I put one of these in my son's car driving two 8 ohm subs wired in parallel and the frequency control doesn't seem to do much, if anything. Just wondering if I happened to get one with a bad potentiometer or something. Thanks.
I used this in a friend's car with a factory stereo and from what I can remember the crossover frequency adjustment worked well. Maybe not as good as a store bought amp, but I could definitely tell it's working.
Nice video. Did the step up create any noise? I am building a BT speaker and I am wondering if going from 12v (3 18650 in series) to say 18v would cause any noise or battery problems. Any advice? Thanks
It's now installed in a car with the step up convertor. It's powering a 10" subwoofer for a while now and here haven't been any issues. No noise in the sound system, and no issues with the car's bluetooth connection either.
Yes on the noise but not always noticeable on a sub. Three 18650's will drop to 9 volts or less as you run them down and the cheaper QSKJ 150w dc-dc converters will start cutting out at less than 10v input (not sure about the one the OP used here). If you're running 18650s its better to just go to a 6s pack IMO. With a 3s pack you should be 3s2p to keep up with the current draw anyway.
How to Add trebble speakers with this amp?
hello can i use 2 ohms 8' 250 watt subwoofer speaker on this ?
Would this amplifier handle a 1ohm 8inch sub?
Hello there.were u able to test in a car?if yes,could you please tell me how you connected it to get power?thanks
Hi. I have it to a friend to use in his car and it worked very well. The voltage booster was also used. I used a little plastic box and installed a SPDT automotive relay connected to the remote turn-on (accessory power) to switch it on. Since the relay is capable of 30 amps and this amp only draws a maximum of about 4 or 5 it worked perfectly. And the amp never even got warm.
cafe80s thanks a lot for the reply.im curious about the relay.how did you wire it? I would like to do this project and use a nexus tablet as my stereo.i already have it installed but it’s connected to the car stereo for audio.do you think this amp can drive 4 car speakers?
@@PaakoBravoo It can if wired correctly. It depends on the impedance of the speakers on how best to wire it up. What is the ohm value of the four speakers?
I know this question is a year old but hey...
Which female DC power jack plug socket could I use to mount on the back of my enclosure for this board? Thanks..
Anything you choose really. It's probably a good idea to choose a common laptop plug size though.
@@cafe80s ok, so it looks like a standard 2 pin since the back of the power amp is two lead.
Not 3118, my mistake! 🤐

is the other knob a low pass filter?
Yes. One knob is for volume, the other is for the adjustable low pass filter.
I have purchase this amp and i wonder if its good idea to power this amp with 18v of batties. Will this not work properly?
It should work well, but I don't know how long the batteries will last of course.
I'll have a rechargeable batteries incase it runs out. I'm just powering this amp with my subwoofer Logitech 625.
Yes an 18v battery from a drill or something like that would work great. This amp will operate at any voltage between about 10 and 25
How well is this amp rejecting hum?
No issues with hum... Or any other issues either.
You said TPA3118 ?? thats a TPA3116 not a typo lol its a audio-oh lol .
Haha, damn it!
My ONKYO integrated amp has a single line out ( One RCA female out ) for an active amp. Could I use this output and use a single male RCA to male RCA cable connected to a single Female RCA mounted on my passive sub then wire this to the board? Thanks in advance and cheers for this video 👍
I've used this amp with just one channel hooked up to the input. Use the included cable with the JST connector and solder an RCA to the other end. Most receivers have plenty of oomph at the sub output to drive this amp to full output. Keep in mind that these little amps will only do about 55 watts into 4 ohms or 30ish into 8 ohms so make sure you use a subwoofer with a driver that is fairly efficient.
@@theAGanimators Ok, thanks Glenn.
The sub isn’t receiving a clean signal
What price sir?
