i just installed my n2 and it works fine but when i turn up the amp for my subs all the speakers including the mids and highs go krazy and seem to have a seizure i checked to see if any wires were touching and nothing i even borrowed a radio to see if that worked but the speakers did nothing wrong i think its the unit can anyone help

you might be running two xovers at the same time. try turning off the crossovers from the unit.
