they are a dual 4ohm voice coil and i am wondering about power they are rated at 2000watts nominal and 1000 rms. As far as the go with one thats in your budget I can figure out my budget once I know if they can hold something stronger than what I have I can get good prices on most brands from the shop i go to. I am wanting recommendations on them cause I know people run them in competition but they never say what amps are on them
