I’m impressed with this little amp board kit. The only gripe I’d have is the little fan barely making noise but that’s nit picking because it’s whisper quiet. Back to positive feedback. 1: Driving retro JBL speakers from the 80s with 5 1/2 inch drivers. 150w 8ohm. Sound perfect. 2: Bluetooth links with Apple TV4k. Flawlessly 3: Driving 2 40w exciters with 1 50w shaker from sub channel. (Have to turn down gain and volume still). 4: Links to iPhone flawlessly. 5: Sub channel has separate volume and gain. 6: bass and treble have separate gain. 7: Volume control. 8: Quality heat sink. 9: Plenty of power to drive power hungry 80s speakers. 10: Tiny footprint with plenty of undistorted sound coming from speakers. 11: Quality capacitor array. I’m honestly impressed. My recliner rock and rolls and I’m only using 16vdc @4Ah and I could add 1 more bass shaker easily. If I turned up the gain and volume on the sub channel I’d blow up chair.

Thoroughly impressed! When I first purchased this there weren’t many reviews. I took a chance and I’ve got to say it’s been an outstanding purchase. I hooked it up to some Bose speakers an active pioneer subwoofer I had in the garage. This board can push some power into these speakers and sub! The key is to have a higher voltage power supply. I tired it with a 15v, it wasn’t enough. Bumped it to the 32v and I was jamming! It’s small and easy to assemble. Doesn’t take up too much real estate. I just can’t believe this little board can put out the power it does. The BT works perfectly fine. Very happy!

I have an old farm truck that didn’t have a stereo so I bought this to put in it. I run 4 speakers (two speakers per channel) wired appropriately and a 10” subwoofer. It’s running on 20v through a 12v-20v step up. Super loud. Bass from the subwoofer is pretty powerful for how small this thing is. Sound quality is clear and overall pretty decent. The reason for 4 stars is because the “frequency” knob that is used to adjust the pitch of the subwoofer doesn’t seem to do anything. I have used other amplifiers like this one before and that knob does create a minor but noticeable change in the sound of the subwoofer. Not really that important though and works great otherwise.

Assembly required though it only took me a whole of five minutes or so without instructions. It's surprising sturdy for its appearance. I've got this amplifer connected with a 24v source and it's sound quality it provides to my two high RMS 6.5" speakers is astounding. It will almost deafen you with the capability of its power output. With the convenience of bluetooth, USB, auxiliary in, the adjustable treble and bass. It's a far better alternative to those higher priced amplifers that have lower power outputs and claim to be high quality. This amplifier is solid and I plan to purchase more of this sellers products as they have many applications and are very lightweight and portable.

I own a lot of chip amps and this is the highest power one that I've picked up so far. If you've used any other TDA chip boards then you know what you're getting into. Sound quality is pretty exceptional for what you're paying, and the power output when properly spec'd is outstanding. I am using this one for a homegrown portable column array + subwoofer event speaker setup. I have hooked this up to a regulated bench supply set at 36v and run it with speakers wired to take the full rated WPC power at 4 ohm loads. It goes to ridiculous volume levels with no audible distortion and draws far fewer amps than the spec sheets and PSU requirements would suggest. I think I saw a peak of less than 4 amps of draw, whereas I was expecting twice that or more. The unit runs cool, especially with the fan running. The fan is very quiet, too. You won't hear it at all in a public venue. Heck, you can barely hear it in a quiet room. I am not sure if the variable crossover is just a low pass for the sub, or if it is a high pass for the stereo pair as well, but I make passive crossovers for my speakers so I haven't worried about it nor tested the output with an oscilloscope either. Anyway, this is a cheap, clean and powerful little amplifier if you load and power it properly. I would highly recommend it.

For an amplifier, it's a great price point and has great output power. Fan is a little loud, but I unplugged the fan and it stays cool when not driven hard (running at 19V). BT audio processing time is a bit frustrating. Unlike most of my other bluetooth audio devices, there is a delay. While it's not significant, it's enough to drive you crazy when watching a video of someone speaking (slow speaking is not as problematic). For music however, or any other source that does not require audio and video to be perfectly synced, it's fine. Aux input does not have this delay, only bluetooth. UPDATE: Changed from 4 stars to 3, due to what seems to be an input threshold required to output sound via bluetooth (kind of like a a subwoofer amp that turns on/off automatically when it detects input). Listening to some classical music, I noticed it cutting out between notes. Tested on two different devices (phone and laptop) the same piece sounds perfect via aux input, but the quietest parts are missing when playing via bluetooth. As a note fades toward silence, it suddenly cuts the output completely, and restores output just AFTER the next note starts. This is a MAJOR flaw that means I'll be using a separate bluetooth adapter for this amp, rendering all onboard bluetooth functions useless.

So, it seems like when I connect my sub rated 150W to the Amp rated 220W it just dies and resets. I'm using a 36V Power Supply. It's not ideal, but maybe my unit is defective. I don't know. Edit: it was a user error. Don't mix 4 Ohms Sub with 8 Ohms speakers. 5/5 works perfectly now
