My old amp (4x1 channels) is dead now, so I order a new one. When I received the new one I noticed that it does not have a level control for the Subwoofer Output, like my older one had. The result is that my subwoofer is very loud. I would like to know if somebody can help me to lower the level that my amp sends to the subwoofer. It will be better if I can control it (like a potenciometer).

Thanks in advance
