  • Versatile amp with left/right channels- No subwoofer channel but has good bass response
Color: Black3 ZK-1002T
Works as designed. NOTE - the product title is correct "ZK-1002T Bluetooth 5.0 Amplifier Board 2.0 200W HiFi Subwoofer Audio AMP with Treble and Bass Control. This is a 2.0 board. Further down the Amazon listing there is a different description "Subwoofer Audio Amplifier Board: 100W+100W Bluetooth 5.0 wireless connection, Bluetooth+AUX audio input, 2.1 channel stereo output" Nah, this does not have subwoofer output just left and right (2.0 not 2.1). I like the build quality - it looks to be put together well, and it works nicely with a small bluetooth speaker system. I have run it on 11.9VDC and 19.4VDC, works well on either. ... show more

Color: Black3 ZK-1002T
I wasn't expecting much when I ordered this, figured i like just try.... brahhh!!! This little amp slams!!! Did a dewalt job speaker with some old 6.5 speakers and 2" tweeters i had laying around. Thing slams louder and cleaner than my truck 🤣 super amazed. I can't believe the power this thing puts out. Pocket size amplifier with bluetooth pairing and has bass treble and on/off/volume knob. Its legit! Brah i have a 2000.4 rockford amp pushing my mids and high in truck. It's like 30 times the size of this thing and this little amp got action!!! Hook ur stuff up right ohm wise and sounds amazing. Good stuff!! 👍🏼 ... show more

The best chip amp for boomboxes money can by. Tested and true to not be a clone chip, works the best under 24v.

  • Easy to configure, package and control
Color: Black4 ZK-1002
This small amplifier module is very convenient to package and connect. Both electrically and via BT. Music is clear and representative depending on speakers used but very easy to setup and enjoy quickly. Great value for automotive and rv applications.

  • This thing sounds amazing
Color: Black3 ZK-1002T
It's one powerful little work horse . It drives everything I have connected to it . Even 15 inch pa speakers. Super clean sound seperates highs and lows Will be recommending to my friends . You will want to have a 24 volt power supply to get it up to it potential output. Very much worth the price.

  • Major connectivity (QC?) problems.
Color: Black3 ZK-1002T
This is decent to power my 30w x 2 passive speakers however, I am at a loss with a couple of issues. Wiring the speaker cables to the screws is a bit tricky, like performing surgery on an ant. Bluetooth connection cuts in an out, more than I like. Wired connection with an adapter to a usb-c device is plagued with noises and instability, no matter how many cables and adapters I tried. Here I have this small and capable device that has issues with both available connectivity options. I am tossing it in the trash. ... show more
