ZK-1002T RPO 2.0 Channel Bluetooth 5.0 Amplifier Board 200W AMP

I bought this amp for a custom Bluetooth speaker I built inside a US General mini toolbox, and it has worked out great. The compact size made it easy to fit inside the toolbox along with the battery and wiring without taking up too much room. Bluetooth connects quickly and has been reliable every time I’ve used it. For such a small and inexpensive amp, it puts out plenty of power for this kind of build. My setup gets surprisingly loud and sounds good, with enough adjustment to dial in the sound the way I wanted. I’ve been using it for several months now with no issues. For DIY portable speakers, toolbox builds, or other small 12V audio projects, this has been an excellent value.

I bought this to make my daughter a turtle box diy and worked perfectly the quality is great and sounds even better! The sound quality/ clarity To be as small as it is! If you’re planning on building one for yourself you’ll want this component! I put some thread locker in the studs when I put it together just to be save that it don’t loosen the screws. Probably didn’t have to but we did. The Bluetooth is strong and fairly good range on it. The knobs to adjust the volume / bass / treb are smooth and adjusts nicely so I was very satisfied and ran it for about 4 hours and didn’t overheat or shut down at all! Looks professional after you build it!

Using this with a TONEX and a 212 V30 cabinet. Sounds good, punchy, clean. Does an excellent job reproducing modelled guitar tones. You can run it with as little as 5V, 2A, at which point its like 16 watts and perfect bedroom/GP level. Using it with a 24V, 15A supply, it easily drives the ol V30s as well or better than the 90 pound Carvin toroidal power amp I have used since the 90s. I think technically it is like 62.5W per side at 8 Ohms. Either way, it easily matches acoustic drums, bass amps, and vocal PA. I got this amp in April, and have not reviewed it yet to see how it held up to this application. It has held up perfectly, with no issues, being used at high volume levels for many hours in a row, practically every day since April. It gets mildly warm doing this. It is so small and light, it might as well not be there for cartage purposes. It is superior in all ways to an amp that cost me literally 50 TIMES the price in the 90s.

Surprisingly this small device provided the wattage that I needed to power 130 watt speakers. Make sure to get a 24volt adapter for max power output. I would give 5 stars except for the device needing assembly and being some what delicate, enclosing it in a protective case would be a great improvement. The Bluetooth receiver has a good range overall this device exceeded my expectations.

Love this small mini amp, bluetooth capable and running 100watts x2 peak running at 24v max recommended volts. Love the circuitry because its advance has built in high voltage cut off so it protects the board from high voltage. Easy setup in my custom build speaker box I have in my garage. Using apache 2800, Kicker 6x9, with voltage display, charging port for battery, push button led power button. Very well built amp and for the price and sound quality it provides its a no brainer for people building custom bluetooth boxes.

Has good sound quality for my camper set up. Was easy to install and the bluetooth option connects to the smart TV with no issues. Think it was worth the money.

Nice and compact! Sound is good. I used it to make a bluetooth speaker for my work truck

This little amp surprised the heck out of me. Powers 2 desktop speakers very well and they sound great. Bluetooth connection seems to work very well, as I have paired this to my phone and then my tv. I would certainly consider purchasing again. Just make sure your power supply is adequate. According to the output, 12v@ 16 amps or 24v@ 8 amps. You can get away with half of what I suggested and it should work fine. If you use a less powerful supply, you will run into heat issues because now you're starving for current. And I would assume it will also affect other features. I doubt this thing does 200 watts rms.

Very good product exceeded all expectations

Very nice product 👍👍

Works great some distortion when maxed out but that could be speakers or the fact I'm running it at 18v

Good sound quality
