[QUOTE="Buck, post: 8791956, member: 591582"] There’s a ton of factors to this. How good your box is can determine how much power, both mechanically and thermally, your sub can take. What frequency do you plan to use 1000 or 1500w? Amp gains set to 1000w @ 40 hz in a ported box will not put out 1000w at 30 or 60 hz. If the amp does, that’s magical. I tune by ear and sometimes by smell; usually I try to avoid the smell part, just depends on how much output you want. Your sub might take 1500w on a mild temp day, but it might not on a summer or winter day, and not due to heat, but changes in the speed of sound due to temperature differences. If you drive to the mountains from the sea, your box tuning will change, so if you set your gains for 1000w at 40 hz at sea level, then it’s not going to be that in the mountains. And that’s why I tune by ear. You’d need like a quantum computer to perfectly set gains for all possible scenarios. [/QUOTE]
