Hi, hope you pay attention to our shop! #jerrymaou.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 power storage and heat dissipation, and stable power 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 power interface of this product, even if you don't have a DC head adapter or battery, it can be easily wired.

Tip:
To have enough out put power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound powre. Please pay attention!
Power 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 power switch on the board is the 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 the DC plug on the machine for a long time.
