    Replacement for an old Marantz type big amp, running from a separate CD player into Gale speakers this is tiny, simple and sounds every bit as good so far. If it lasts then easily the best few quid I’ve spent.

    A great bit of gear for minimaI cost.
    I use 3 of these for a PA system with 2 x front facing & 1 x ‘foldback’ 10” 8ohm professional speaker cabs. I only use one of the two stereo channels on each amp. There is easily enough power for a small village hall and more than enough for a domestic property without a visit from the police! Each of my amps is powered seperately by a 12v 5AH Lead Acid batteries with inline 3A fuses. Easily works for more than 6 Hours. The amps run ‘cool’ all of the time. To my ears, they have an adequate frequency response i.e. bass to cymbals.
    Now the technical stuff. Fistly, I am a qualified, experienced electronics engineer. These amps are class D technology. Even if they were 100% efficient, the maximum total output power possible without exceeding the rated maximum DC socket rating is 12v x 5A = 60 Watts, so 200W per channel is completely impossible. Very likely it is around 5W RMS into 8 ohms & 10W into 4 Ohms. I haven’t yet checked whether the amp speaker outputs are short circuit protected, frequency response or distortion. I’m too busy presently, but I plan to check these later this year. If I do, I will post again with results. So in the meantime don’t short circuit the outputs.
    28/12/23 UPDATE: Although I haven’t completed all checks I have found something important. POSITIVE & NEGATIVE SPEAKER OUTPUTS ARE AT HALF DC SUPPLY VOLTS. So all are approx +6v with a 12v supply. SO DON’T CONNECT EITHER OUTPUTS TO GROUND / 0v. There are TWO bi-phase amplifiers per channel which means that there is 24v peak to peak signal to the speaker. This will be 10W per channel with an 8 Ohm speaker, 20W with 4 Ohms. However, personally I don’t think the 12v DC supply input socket is really suitable long term for this power output in stereo 4 ohm use. Peak power supply current could be 12A with 4 ohm load & 6A peak with 8 ohm. There is no noticeable distortion on an oscilloscope display. Further updates whin available.

    The product it self is great but there is no power plug for this device it would be great if there was a plug and not to be able to buy a plug

    Ordered this little amp to add some power to a Bluetooth receiver and a pair of bookshelf speakers in my kitchen. It works great however…. There is no power unit with this amp, you have to have an existing 12v adapter plug that fits! I’m not sure if it was me not reading the ad correctly or not but I’d expect anything that requires a 12v adapter to be supplied with one! It was very lucky I had one otherwise it would have been going back. Anyway it does the job!

    This was bought for panel speaker experiments.
    Fast delivery but it would not switch on despite trying 3 known good 12V power supplies.
    Utter rubbish. Being returned to Amazon.

    by Much better than you’d think!

    I has some spare Onkyo surround speakers from a faulty HDX system and thought I’d try one of these as an upgrade for my home office – so much better than the laptop speakers and a bit of re-use rather than buying complete speakers.

    Pretty easy to set up – 12V 3A power supply (not supplied but I had one), 2 speakers, some speaker cable and a 3.5mm to phono cable (which I had).

    Sound quality seems fine for what it is – at around £12 you can’t really go wrong.
