I used a 50hz tone at 0db from two different websites and i set my amp using one of them.. then i played the other one to see what the ac voltage would be and it was 3 volts higher than when i had used the other one.. but they were at the same volume.. why is this.. and should i set my amp differently.. i played some songs on it at this setting and the amp never reached the ac voltage that i had it set to on the 50hz tone on any of them.. And also this might be kinda hard to understand cause i dont know how to word it.. but.. if i set my amp to put out 40 ac volts to the sub so that it doesnt clip.. then as long as a song doesnt play more than 40 volts thru the amp to the sub then the sub wont clip? no matter the hertz? sorry if i'm confusing.. Also if i am correct on the second question.. then is there a sensor or something i can get to let me know when my amp is putting out more than 40 volts to the sub?? |

One may have been off. You can't really rely on free stuff you find on the internet, after all. Really if you want an accurate test tone, use a real tone generator, not a WAV file you downloaded from a random google search. |

I dont know if my amp is under or over rated.. It's an alpine mrp-m850 on a RD Sonance V2 15" Someone told me to use a 50 hz tone at -4 or -6 db to set it for daily applications.. I just dont know what to do.. |
