ZK-1002T PRO 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass, BT USB and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers

This is a really surprising little unit! Packs a good punch. It sounds great, two 6.5 components with tweeters and a massive audio hippo 8, it is power hungry. I cant believe it pushes my sub, it doesn't pound but wow it sounds good! For sure use a good power supply for wall plug in or 20v drill battery.

Excellent Little Amp for DIY Bluetooth Projects I used the ZK-1002T Bluetooth amp in a custom portable speaker box powered by an 18V battery, and it absolutely delivered. For such a compact unit, it puts out plenty of clean power—more than enough to drive my 6.5” marine speakers with solid volume and clarity. Bluetooth pairing is quick and reliable, and the sound quality is surprisingly good, especially for the price. I also like that it supports both Bluetooth and aux input. The compact size made it easy to mount inside the case without overheating or needing extra ventilation. Just be aware that there are no instructions included, so if you’re new to wiring or amps, you may need to reference some diagrams online. But for DIYers who know their way around a project, this amp is a solid choice. Highly recommend for anyone building a battery-powered sound system or portable speaker setup.

Works well for my diy boombox. No static/hiss like some of the cheap(er) ones.

Easy to wire, great tuning and sound quality, more than enough power for most cases

Funny little assembly project to tinker with. Good output, reasonable power requirements, Bluetooth audio quality no different from the aux in. Only a couple nitpicks from me: Small screws for the output wires that can't be used with large connectors, and I can't enable/disable bluetooth... I live in an apartment complex and my upstairs neighbor keeps accidentally connecting because I run the amp on its aux with my PC. I can't disable the aux with a physical switch to prevent this, and the BT remains open and in search mode. I also can't rename the BT connection internally to say something like "APT xxx BT amp" to let people know MY device isn't the one they're looking for when they try to connect to their devies.

This unit worked great. Connects very easily via bluetooth. Puts out plenty of power for two 6” speakers and a tweeter. Running 2 old 6” speakers from my car and 1 tweeter with this unit on a 5ah Milwaukee m18 battery with 12v adapter. Battery easily lasts 4 hrs on half volume (which is loud). Best part is if it does die I have multiple batteries on hand. Does obviously need a 2 way crossover for the tweeter. Cons of this unit would be that it’s not already put together. Which is odd to me because you can attach the speaker wires in with the outer casing installed. Screws are very tiny that come with it. Also I do get a small amount of interference with the bluetooth but not enough to annoy me. Could be the power source.

Wow this thing actually works. Pushed my speakers and I added a subwoofer. Actually sound pretty good.

works great, good sound

Very good product exceeded all expectations

me sorprendió su potencia y nitidez, el control de bajos es muy bueno, no distorsiona, superó expectativas

छोटा पैकेट बड़ा धमाका ❤️❤️

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

Best quality audio amplifier
