I have a question and it might be silly to u but to me its not because i dont know. I dont have an oscope to set my sub amp so i just use my DMM and a 60Hz test tone. I want to set my LPF and sub sonic filter but the dial only goes in range from 15-55 hz for sub sonic and 50-250 hz LPF. I have an idea where 25hz is on sub sonic and 80hz is on LPF but i though if i could use a 25hz and 80hz test tone with sub still hooked up and tune it with those tones, my though is that the the 25hz tone wont play lower than 25hz if i tune the amp untill i dont hear it anymore then move it up a notch and thats 25hz. How far off am i from this ? I just have the basic equipment no fancy stuff yet...
