REES52 2.1 Channel Audio Stereo Amplifier Subwoofer Board; DC 12-24V High Power 2x50W 1x100W Sub Output Super Bass Power Amplifier Amp Ampli Module

SO far so good....it gives seperate bass output foe sub woofer....so no more trouble listening....Works just like a home theatre works

Its poor quality product and I used few days only because of the different type of noise will come after increasing volume. Thank you..

The amp sounds good however it can be better as well if they had better controls on the potentiometer...It's frequency is unstable...So I may have to try another set of potentiometers...Connected Sony Xplod front speakers and a Sony Bass from Sony SA D40 modelPlays good however the only reason of 4 is due to potentiometer controls

After my experience with a TPA3116 based 2 channel amplifier, I decided to go for this as I was building a 2.1 system. Now my setup was as below:L-R channel -> 2x 6.5 inch drivers rated at 45W RMS @ 4 OhmsSubwoofer-> 2x4 inch drivers rated at 40W RMS @ 4 Ohms (wired in parallel so effective impedance was 2 Ohms).PSU-> 90W SMPS (19V 4.7Ampere){ Class D amplifiers prefer SMPS}Now the issues with the item:I don't know whether it's the inductors that have been used are too small, saturating them quickly and easily or something else but pushing the amplifier beyond 70% mark on a low-frequency song sent it into OverCurrent protection, thus output pops/stops momentarily and then resumes. This keeps on happening till either the volume is turned down from source or on the amplifier. Removing subwoofer from the equation doesn't helps either. I mean I wasn't even pushing the device to it's "rated" values and still it peters out. Using a bigger PSU (24V 10A) didn't help either.Other issue is the high quiescent current going through due to the use of bigger Potentiometers. This produces screehy-hissing sound when either the subwoofer potentiometer is turned all the way up or when the Treble Pot is turned all the way down. After doing a bit of research, I found out the reason to be use of 50K Pots. Swapping them with 10K Pots fixed the issue there but I couldn't do it as I wasn't able to locally source Dual Gang 10K Pots. REES52, if you are reading this, please update your product and look into these issues.So verdict is, if you want something small that sounds OK at low to medium audio levels, it will do the job. If you want things to bump or get loud while maintaining fidelity, this won't do.

Good Sound, make 24V - 5 Amp power supply using with Sony Tower 2speakers and bass tube

Plastic case shown in picture but i received a different one. I thought it was an assembeled box.but inhave to assemle it.but the amp volume teble bass is not get inserted to the box.

Awesome product 👌👌👌 1st use experience.. good build quality.... only to see, is it durable or not....i will review after a month again...

Not same as picture...the bord is damage some parts are lose ND the plastic Case is different can't fit on the bord
