i have a pioneer dehp-3600 and much like all other head units it has a ton of equalizer type stuff can someone tell me what q factor is all about. I know it is curve characteristics but you can adjust the lows, mids and high frequencies and the q factor for each of those low:40-80-100-160hz Mid:200-500-1k-2khz and high:3k-8k-10-12hz and the q factor:2n-1n-1w-2w. I know it may depend on your preference but what is a decent spot to adjust all these at
