[QUOTE="akillj, post: 8305565, member: 644272"] That's kind of an illusion. Bass boost essentially turns up the 'gain' on one frequency. (Typically 40hz) Don't use 'bass boost' it's absolute sh*t and you're probably clipping. What's the DD1? Like $150? I always love to advertise the DSO Nano every chance I get. Just because I feel it's such a useful tool and is Nobody can tell you what gain settings to use. If there was a perfect gain for all amps, it would be internally controlled. Your amplifier is always putting out as much power as it can, for the input voltage the gain is set to. LPF and HPF (Sub sonic, same thing) are a little different. LPF is personal preference, this won't hurt anything. HPF should be slightly lower than if not at port tuning. Frequency's below port tuning start to let the sub(s) 'unload.' Meaning they'll be moving as if they're in free air. This can cause over-excursion and possible woofer failure. You can use a DMM to set gains if you really are on a tight budget.
