The jl100/1v2 puts out the same amount of power between 1.5 - 4 ohm loads so you dont have to really set up anything to match your sub- wire the coils in parrallel and plug it in- set infrasonic(subsonic) filter at 15 hz(lowest) set crossover piont at close to 80 hz set gain about half-or if you kow the voltage from your source unit match the source voltage to the amps input voltage setting-it should pound like a champ with no problems
