Bluetooth Subwoofer Amplifier Board Hifi Stereo 2.1 with Treble and Bass Control Regulation 2X50W+100W DC 12V-24V Audio Power Amplifier Module AUX Input for Store Home Theater Speakers

Its doing the job perfectly. Im very happy and surprised about sound quality. Will defo recommend to buy. Im Very happy 🫶🏻

Something strange the subwoofer is rated for 100w on the board but it pushes my twin edge 12” 1800w subwoofer to its limit 🤷🏻‍♂️ overall great little thing

The media could not be loaded. The 3.5mm Input Jack is playing Mono not Stereo. BLUE TOOTH is Stereo and sound is Incredibly Amazing. 2 stars is because 3.5mm Audio Jack is momo. I have 4 of these Amps. The 3.5mm Cable used is playing Stereo on all other devices and Headphones.

As others have said, it doesn't come with a manual but it's relatively intuitive to put together. Overall it's a huge upgrade to my soundsystem, my old amp definitely lacked bass and having control over the bass and treble allows you to perfectly balance the audio. For what it can do, it's a bargain and couldn't recommend it more. I do suggest getting an adjustable power supply as it makes quite a difference, depending on how many volts you put through it

Bought to run 2 little satellites plus a sub for a media box. The amp worked well via Aux/Bluetooth for a couple of months, sound quality and EQ were good with little distortion. The amp then gave out for no apparent reason - turning it on now does nothing - no obvious damage, guessing a component has failed.Outside of the 30 days return window unfortunately - perhaps worth spending your money on a more solid unit.

I’ve tried this in my camper to power some separate speakers instead of having to run it through the car stereo for a number of reasons, one being I can use the leisure battery for this rather than the starter battery for the stereo. The build is odd, it’s a little kit with spacers and a metal body that doesn’t encase everything.Putting it together is easy if you’ve ever done anything like building a raspberry pi or touched a circuit board before, I don’t know why it can’t come complete in a plastic pi like case?Annoyingly you don’t get any power adapter with it and it doesn’t have a screw down terminal for the wires so you need a correct rated adapter, I used some little push on connectors for speaker wire and made them fit then electrical taped it to cover up. The whole time I’m thinking “is hiding away a metal box with voltage going through it near a van chassis a wise thing to do?”I connected my ceiling speakers to left and right and connected the TV through the 3.5mm Jack and it worked straight away, the volume was set half way and controlled by the TV after that and it was fine, almost as good as the stereo sound but that has got a small sub and 6 speakers and this was only connected to the two.There was no delay in it powering up, if the volume is up at all you get the clicks and pops of it coming to life through the speaker which is not the best but can live with that.All in all it’s a good way to connect things up, a little annoying some of the choices they have made, for the 12v there surely could have been a screw down connector or at least the adapter end with a short wire that you can crimp onto.It works but not sure I trust it all the way.

For the money great bit of kit,

So the reason behind getting this Amp was to add a second Sub woofer to Denon AVR 7.2 ch set-up. I had an extra passive sub from an old 5.1 system.Denon AVR does have 2 pre amp sub out. One is already connected to an active sub which also has a line out. I wanted a little more extra bass. Connected the new amp up to the line out to power the active sub. After some finicky optimisations, I started to get ultra low freq bass output. Not over powering, but really filling low end bass which I like.Pros & ConsPros: Sound quality: Bass range is pretty good. It's ideal to set freq pass to the Lowest setting. You get the ultra low frequency bass really humming in your ear .Build quality is excellent for the price, the metal casing and screw assembly is sturdy.Theres a certain weight to it, so it will sit on surfaces relatively stable.You can even add a mid range sub to the R&L speaker output along with the dedicated sub out.Control knob mechanism is smooth and progressive . You can find your optimum levels comfortably.All the coonectors are well anchored in the PCB.Cons: There seems to be a low humming noice sometimes. Not entirely sure whether it's my adapter (not supplied)I changed DC adapters & but still getting the hum. It can be very negligible one you adjust the freq and and volume. From a distance it's not audible.Power adapter: I'd be happy to pay extra few bucks for an manufactures own adapter.Over I'm satisfied with the performance and build.My plan is to fit it in to the sub enclosure.
