i work with dual 6 ohm subwoofers and i dont work with 1.5, 3, or 6 ohm amps. i would like to know if there is a way to figure how much an amp would be pushing. in a (i guess normal) situation i would have a rating of X watts at 4 ohms bridged but im not always at 4 ohms. could anyone tell me what a formula might be to figure for insance an amp that pushes 500 rms at 4 ohms bridged to a 3 ohm load?

If the amp works at 2ohm split the difference between it and 4 ohm. that should put you in a really close ball park. If the amp makes 500rms at 4ohm and 1000rms at 2ohm then it will output right at 750rms at 3ohm.
