So long story short trying to use 2 10" subs from a car from my home and been having problems finding an amp for it but really my question now is what is "rms" to "watts"?
my subs are 12vr, 2 ohm, dual voice coil, 400rms/800peak
so why does ohms law tell me that a 12v 2ohm circuit only need 72 watts for power?
