• DC power supply is designed to supply power directly available 12V battery voltage range: 9-15V, recommended voltage 12V, output power up to 15W + 15W, the peak power of 30W + 30W, the sound volume is small but super shock for any occasion.
• Sound quality is super good - treble delicate, soft, transparent, no harsh; bass strong, full, strong, and acting freely.
• Size: 50x50x42mm (length x width x height, without potentiometer handle), ultra-small size for any space.
• The power amplifier board is imported TDA7297 two-channel amplifier chip.
• No current impact sound boot, high fidelity no static noise!

Product description: Chip Type: TDA7297 Dual-Channel Amplifier Chip Power Supply: DC 9-15V, Recommend 12V 2A Output Impedance:4-8 ohms efficiency: up to 90% Output Power: 15W+15W Product features: Dual channel It has 2.0 dual-channel with each channel is 15W(15W+15W) and can be connected to 4-8 ohm 10-50W speaker High efficiency & low consumption It has high working efficiency which can be 90% while low power consumption. For example, with 12V car battery as power supply, it can work for about 5 hours or even more hours. Small heating It has built-in heatsink and is a small heating generator. By the way, if you frequently use very high sound, our suggestion is you can buy a larger heatsink. And please no worry, as if you use a larger heatsink, there is a fixing hole for larger heatsink. High-quality component High-quality FR-4 fiberglass board and high-quality CBB capacitance are used in the PCB board, therefore, there is little or even no sound when it works and its capacitance can be as larger as 2200UF. More, although it is tiny in size, it output large and healthy sound. Easy & convenient With the help of screwdriver, its wire is easy to be connected, you even don't need to find the eletric iron. More, as there is the potentiometer knob, it is easy to adjust the potentiometer. Package Includes: 1x DollaTek Mini Amplifier
