Man I had to look at it and think about it for over a year. I had something in my head telling me I was not getting the power I should. 1800watt RMS mono block amp to 700watt audiobahns and it just didnt sound like it was hittin hard. Finally I checked it today after being lazy for so long and the damn shop wired the subs to a 4ohm stable connection. They were suppose to be run at a 1ohm stable mono load. Did that today and god damn i almost threw up from the damn bass. here is the diagram on how they are wired. Its the top right one. Two speakers 4OHM a peace.
