For Example, If The Output Is 60w But A 10w Speaker Is Connected, And The Volume Is Turned Up, Lag Occur, And The Speaker May Be Burned Out. The Noise Is Too Loud When Playing Music, Or There Is A Background Noise Even When Music Is Not Playing. The Function Of The Power Amplifier Board Is To Amplify The Signal. The Main Source Of Noise Is The Radio Clutter In The Environment That Is Amplified By The Power Amplifier Board, So As Long As There Is A Power Amplifier Board, There Be Noise. When The Volume Is Turned Up, The Sound Freezes And Is Intermittent. After The Volume Is Turned Down, The Sound Can Be Played Normally.

Most Of The Noise Is On Some Old Front-End Boards And Is Incompatible With The Power Amplifier Board. You Can Add An Audio Isolator Or A Coupling Capacitor Test To See If It Can Be Removed. Professional Installation Is Required To Avoid Product Damage.
