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.

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.

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

Very good product exceeded all expectations

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

Very nice product 👍👍

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