Kenwood SW-500 Super Woofer Active Amplifier Powered subwoofer. Item work but makes buzzing sound without playing. Don't know much how it works as I bought it for a project. There are marks, scratches and paint stains on it. No remote or any other accessories attached.

Item comes exactly as pictured.
