I connected the amplifier to my car . It's very loud, but, while the engine is working, I can hear my throtle throu the speakers that they are connected to the amplifier while I'm driving. Even without music and with the amplifier's volume at min, I can still hear the sound of my throtle throu the speakers. Crazy! It's like I hear a small turbo sound throu them. But it's working. For now at least.
