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

I have a little project going on with this amp and its performance is amazing! The sound quality and volume can be tuned in the board or remotely through an app. I use a 24v power supply (not included) to get the best sounds quality and prevent over heating but I will still add a 40-40-10 fan to its heat sink. I used it on Bluetooth only but it does have an AUX as well. Well built product with labeling and easy to put together.

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.

I've been using it for 5 days so far, and it works great. • The residual assembly was very easy (anyone with adequate fine motor skills should be able to do it). • I'm using my old laptop charger (19V, 130W), and it delivers more than enough power for my 4 Ohm speakers. • The sound is crystal clear, and I didn't notice any distortion coming from the amplifier itself. • Bluetooth (the main reason why I bought it). works without any issues. NOTE: the unit does not have an ON/OFF switch, so it always stays on. I will be installing a simple inline switch later to be able to turn it off when I don't need it. Overall, it's an awesome find for the price 👍

I made a simple sound system in the garage. I don't care for blasting volume, but I do care for sound clarity. I have an 8in android tablet connected through aux cable to this amp, and to 2 stereo 4in shelf speakers. Impeccable functionality and sound clarity. I found in a drawer an 18v 2A adapter with a 5.5x2.1mm jack (the most common) and it works great. It's very small but rugged. I mounted it discreetly under the work bench so that I have access. Important: it's not specified anywhere, but I noticed accidentally that the volume button has a press function. Long press (3s or so) turns it off for me and I need long press to turn it back on. I haven't tried bluetooth because I prefer the aux connection with less interference.

Needed to be put together overall works great.

I used a 12v lipo battery for the power supply, and it worked great. Nice and compact for its power and what it does. It gets loud!! Very easily the best value out there for DIY speaker amps. No remote control. Bluetooth connection seems good.

Used this for a two-way radio base station. It provides great, clear, and loud audio. The kit was easily assembled, and has upheld well for over 6 months. I wish it would have came with a plug for an outlet.

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.
