Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve.    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ecolour: green    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMaterial: plastic    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePackage Contents:    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e1 x Digital Amplifier Board    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOnly the above package content, other products are not included.    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNote: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
