Hi, I have a question as to what happens if I hook up my Rockford Fosgate 800a2 2 channel amp to my Alpine type X DVC sub. When bridged, I understand that I will load the sub at 4 ohms. What happens if I run both the channels to the sub? like use the + - on channel 1 of the amp to the + - on channel 1 of the sub and the + - on channel 2 of the amp to the + - on channel 2 of the sub?
