I might have to try -2.5. For now I started with -0 and the wife is asking of I need nore bass. The easy answer to that is yes. I might have too much high, but sounding way better than before my amp swap. Snowdrifter, thanks for the files. I think I might have to try a -15 on the sub amp now.

all of the tracks below 0db shouldn't clip unless your music does :X

0 db shouldn't clip unless your music does. -2.5 will clip if the music is louder than -2.5. Usually it isn't but it's not unheard of. Same with -5. -7.5 will clip if your music is louder than -7.5db. And so on

Glad I could be of help!

I wouldn't suggest using -15 on the sub though. Been there, done that. Clip city lol. Highest I'd suggest is -10, and that's if you don't listen to any sort of bassy music. TBH I'd go with the -5 or -7.5 for the sub amp

old thread blah blah blah

Maybe it's been talked about but what role does Impedance rise play in this? Is the -10 across the board and doesn't matter what ohms are at? OR will the impedance rise (loss of watts more or less) allow for less clipping with the -10? Am I over thinking this or am I completely way off?

I suppose even if you are under powering your sub; if the gain is too high it's still dirty/clipping signal correct?

Think of it like this: Gain is only the ratio between input voltage and output voltage. Your goal is to set the gain as high as possible - to the highest voltage without clipping or distortion.

Not going to go into great detail, but for the sake of explanation:

Box rise is a change of impedance across a frequency range. And power is V2/R. To tie it together: You hold your amp's voltage (gain) constant. Your box rise will change based on a given frequency, and when your ohm load changes, so does your power output, in accordance with the equation above. Higher box rise = less power output.
