Gain isn't a one setting fits all.

I'm not sure how your sub's LPF attenuation works but if you are using the amplifiers crossover then you should be able to set your subs crossover to 0. This is sub dependent tho, some subs that have the option will simply bypass the the crossover. This will only help if the crossover was negatively effecting the phase of the signal. Speaking of which, does your sub have a phase/delay dial? If your sub is out of phase it will also hurt the quality of the sound.

What's the best phase option 0,90,180,or 270? I never understood what this meant so I always kept it at 180. Thanks
