true but what i find is since they are so rigid when you get an answer to a question it is pretty much cosigned along the same lines by the others who answer and you can pick out the real from the bull a lot easier. here and some of the other boards answers are all over the place so it's harder to get a direct answer. but amps and wiring real dead on answers allday. i guess the way some good subs are underrated so many different ways it might work for some but not others. i had so many conflicting answers when i was building my box for my sa-8s that i passed over some great info that after building the box i now understand.
