[QUOTE="ExplsvCookie257, post: 7255845, member: 624778"] ok Im going to try and help you out . . . First set your Low pass filter on your subwoofer amplifier to around 80hz if it swings from 50 to 250 10 to 11 o'clock should be around 80, or you could get an 80hz test tone and turn the pot till the tone becomes quiter then go back a little and your in the ball park. Second set your subsonic filter to around 25hz there is a formula I have heard of people using I think its 3/4's of the tuning so 26hz. Most amps are not marked only the limits of the crossover so again your going to have to kinda guess. Third turn off all equalizers and bass boost on your head unit and turn it to 3/4 or as loud as it will go without clipping. Obtain a multi meter. Do this equation SQRT(rms power of amplifier or the max the subs can take X the resistance of your subwoofers wired to your amp). plug the leads into your outputs of the amplifier with out subs conected some argue to have them hooked up but idk. then turn the gain untill you get the value we calculated erlier. Also forgot to add make sure subwoofer level on the headunit is all the way up and that you have the pre outs set for the sub not the rear speakers or fronts as I have done this and my sub sounded funny. Your subs are known for there sound quality so they should not be sounding bad in anyway. Hope this helps. EDIT: The phase control is for helping the subwoofer integrate better with your mid bass [/QUOTE]
