Bluetooth Audio Amplifier Board, ZK-TB21 2.1CH 50W x 2 +100W Subwoofer Power Amp with Treble and Bass Control, Bluetooth5.0 and AUX Inputs, Stereo Digital AMP for DIY Home Speakers

Very nice product 👍👍

Loved it U could definitely but this one for 2 speakrs of 50w and 1 subwoofer of 100w + there is and extra connector for subwoofer of low output. I got this as my old amplifier was dead which was a 5.1 then I got this 2.1 Just remember adapter is not included u would require an adapter of 12-24V and 8-10Amp for full utilization. In my case I used an old PSU of a pc which works great

Worth For Money. Works Like Power Amplifier, I used 1100 Watts JBL Sub and 4 50 Watts Creative Speaker. the effect was too good. I just kept 70% volume only, sound effect is OMG too good too clear, Used 12V 5 amps power adaptor. That itself gave amazing results. I totally used for continuous 6 Hours no heating issues no power drop. If you use 24V believe me the sound effect its going to be mind blowing

worsted product do not buy, i return this and 7 days over when pickup the product and dose not refund my money. amazon is very bad Flipkart is good because when it resived product immediately refund

Super Sound......very amazing product for 2x100 W woofer speaker.......I used it on Panasonic Woofer system and sound is superb........

Good sound quality

I received an amplifier which is different from what's shown in the image. The amplifier I received has Bluetooth, AUX and USB as input and transmits BT-BLE-APP when turned on but there is no app that I can use to control the amplifier. I tried all the common amplifier apps like Wuzhi and synlink but nothing worked. I sent multiple communications to both Amazon and the seller but received no response and now I'm stuck with a useless amplifier. Won't recommend this to anyone.

छोटा पैकेट बड़ा धमाका ❤️❤️

Very good product exceeded all expectations

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.

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

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