Welcome to the shop, the quality is excellent and the price is affordable! #seyijian.vn
Features:
5.0 Bluetooth version has high fidelity and two-channel stereo sound quality, with higher efficiency and farther transmission distance.
Capacitor 470uf 35V solid capacitors ensure storage and heat dissipation, and stable supply is a prerequisite for good sound quality.
The copper DC connector is used to withstand high current and no heat.
Free DC head lead, compatible with the input interface of this product, even if you don't have a DC head adapter or battery, it can be easily wired.
It also comes with a volume adjustment function, which rotates the chirp potentiometer clockwise to zoom in and counterclockwise to decrease.
Great for DIY speakers.

Tip:
To have enough out put if the audio input is sufficient and the supply voltage/current is sufficient. The supply voltage is higher and the relative will be larger. The speakers with different impedances will have different output . In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound powre. Please pay attention!
supply voltage: 12V--8 ohm speaker/12W(left channel) + 12W(right channel), 4 ohm speaker/20W + 20W
15V--8 ohms/18 + 18W, 4 ohms/greater than 30 + 30W
19V--8 ohms/32 + 32W, 4 ohms/greater than 45 + 45W
24V--8 ohms/38 + 38W, 4 ohms/greater than 50 + 50W
Precautions for use:
The switch on the board is the standby switch. After the switch is turned off, the machine is in a low- standby state. To completely turn off the or unplug the DC plug on the machine for a long time.
