What formula do I need?
I am building a SPL box tuned to 60 Hz. Since this is the frequency of AC current, Could I just use a power inverter to 'burp' the speaker @ 120volts?
What is the formula I need to figure how many amps this would pull at a 2 ohm load? And since the ohm load is so small, will even work plugged into a 120v outlet? Also, how many watts is 120v through 2 ohms?

we have some old viper woofers that dei will take back only if they are blown.
so we plug it in to the wall with a 120v ac i use a green 30 amp fuse and the woofer jump all over the floor and took almost 5 minutes to burn the fuse so it is not going to pull that much this was a 800w woofer @ 2 ohms
