i've got my DMM hooked up to my amp and i am trying to set my gains. the formula i got said i should set it so it reads 40v on the DMM. i've got bass boost and eq's turned off. i turn up the gain until i feel like i am doing damage to the sub and the DMM only reads about 18 or 20. what am i doing wrong?
well im not sure it does, but try using the 50 hz and be ssure to use it a 0db test note. also whatsetting do you have your DMM. what amp do you have what sub do you have?
