Need wiring help.
I am having a hard time wiring my sub woofer. My amp sub woofer out seems to only make the sub have a strong constant HUM and i mean STRONG. The question is can i do this. I am running wires from from front main speaker to the sub like in a series. Is this damaging in anyway? The system seems to work fine right now but I am not sure if it last lasting effects.
