## Description

Product description How to Select the Audio Input Mode This amplifier board has two input modes: Bluetooth and 3.5mm AUX . When both modes input audio signals at the same time, the amplifier board will give priority to the Bluetooth mode; If you need to use the AUX mode, please make sure that the Bluetooth connection is disconnected. ZK-TB21 Bluetooth Amplifier Board Input Voltage: DC 12V-24V Max Power Output: 50W*2（R&L）+100W（Subwoofer） Input Method: Bluetooth & AUX Channel: 2.1 CH Stereo Output Output Impedance： 4-8Ω Bluetooth Version： BT 5.0 Protection Functions: Reverse Connection Protection, Short Circuit Protection, Self-recovery Overheat Protection Size: 120*100*22mm Weight: 195g NOTE Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output. The higher the power supply voltage, the greater the output power; The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker. Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power. Independent Control of Treble and Bass The bass audio and volume can be adjusted separately, and with the left and right channel speakers, the 2.1 channel brings you a richer sound experience. Dual TPA3116 D2 Amplifier IC The maximum modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1%, ensuring high-quality sound output. 50*25*10MM Extra-large Heat Sink The extra-large heat sink can provide good heat dissipation for the continuous high-power output of the AMP, thus preventing the chip from being burned. Warm Reminder The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power. It is recommended to use a power supply of 12-24V, 5A or more, and the speaker power is 50-100W for the best effect! Packing Include ZK-TB21 Power Amplifier Board * 1 Protective Shell * 1 Set DC Plug * 1 Screwdriver * 1 Knob * 5

Review: Well worth the money!! - I am an avid audio addict. I have a massive collection of audio gear from high end vintage stuff like luxman, b&k, marantz, hk and many more as well as 20+ pairs of great speakers, mostly vintage "Heritage" Klipsch. I bought one of these on a whim because I wanted to out some speakers and small subwoofer I to one of my old cars but I wanted to keep the factory stereo head unit in it for the look and hide a small Bluetooth, 12v amp in the glove box. I hooked this up to 2 blaupunkt 6x9's and a 6.5 inch Boston subwoofer and holy crap it sounds fantastic! I have several vintage vehicles and I will be ordering 10 more of these to keep for future conversions. It punches way above its weight class, sounds clean, and clear. I highly recommend!
Review: First impressions and testing are good - not sure about the bluetooth though - Design quality is surprisingly decent. It is not fully enclosed and the sides of the box are open just like the pictures, but the PCB, solder quality, silk screen, etc are all pretty good. Components are obviously not name-brand, but off-brand resistors/capacitors/etc are OK now days it seems like (not sure about long-life though). Bluetooth connection range is OK, reaches through 2 walls in a house at least, but there was a random clicking noise in the bluetooth audio mode even when up close. That's fine for me since I'll be using the 3.5mm jack which doesn't seem to have any audio distortion that my ears can pick up. But I'd be cautions buying this if you plan to use it and use the bluetooth. Power output seems sufficient. They always lie about the "max output" on pretty much all audio equipment, but the same is true for speaker input wattage. I'm running this with about "2x40w rms" car speakers on each channel, 4 total speakers, and it is more than loud enough without clipping, powered through a 20a relay the car battery 13.5v source.

### ⭐⭐⭐⭐⭐ Well worth the money!!

### ⭐⭐⭐⭐ exceeded my expectations. (No cleaning of incoming Aux.. works great on BT)
*by D***R on February 13, 2026*

using for a van office build ... 2.1 computer setup this thing blasts loud and clean on house battery bank: 13V takes only 0.25 Amps at 75% volume. Definitely more sound than my ears can handle. CON: no Aux filter .. laptop is giving out noisy signal, this thing has NO signal cleaning (for ex: prior Logitech 2.1 setups clean Aux incoming audio nicely) .. so only works well over bluetooth .. so pray the connection is stable.
