Smoove Posted August 19, 2013 Report Share Posted August 19, 2013 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.

SnowDrifter Posted August 19, 2013 Author Report Share Posted August 19, 2013 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.

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 Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Karkov Posted December 28, 2013 Report Share Posted December 28, 2013 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?

SnowDrifter Posted December 28, 2013 Author Report Share Posted December 28, 2013 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. 1 Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
