I have a Fosgate Stage 1 Dual 4 ohm 12"" sub in a ported box and its acting a fool right now. When the power is turned on for the car the amp kicks on and the sub starts moving up and down on its own with no music playing and it does this constantly and it sounds like crap. What could cause the sub to move involuntarily of tghe music....wiring? something else....any help is appreciated. thanks
It might be the RCAs. Every time I tap the RCAs on the terminal end where it connects to the amp a loud pop is given off by the sub? Would soemthing like this cause the sub to move up and down on its own with no music playing?
