How loud would 1250 watts topically sound with maximum gain on a subwoofer while played at a normal volume on a stereo? ?

I would really love to know :) I have a 10 inch sunfire subwoofer that I am hooking up.

    The number of watts does not relate directly 

    to how loud a system will be able to play.  


    The sensitivity of the speaker(s) must be considered.   


    Depending on the driver(s) involved, 

    it typically varies from about 83 dB to 98 dB / 1 W / 1 meter, 

    although there are drivers with higher or lower numbers than these. 


    A change of 3 dB is considered the smallest increment 

    the average person will be able to detect. 


    To increase the volume 3 dB, the power must be doubled.  

    An increase of 6 dB requires four times the power of the reference, 

    and doubling the apparent volume (10 dB) requires 

    TEN times the power of the reference.   


    Here's something you should remember: 

    A speaker that is 10 dB more sensitive than another 

    (such as 98 dB compared to 88 dB) will sound twice as loud ---  

    the equivalent of using an amplifier ten times as powerful.   


    However, sensitivity is not everything, because in Most cases 

    the frequency response of a more sensitive driver 

    will have a greater variation in level across its overall range (less "flat")

    than will a less sensitive driver. 

    It's a trade-off.

    .......measure it with your sound meter. That will include the distortion and physical rattling.

  • The gain on the amplifier is NOT a volume control. The gain is suppost to be set to the output signal on the head unit or whatever the amplifier's RCA is connected to.

    It also depends on what type of enclosure the sub is inside of. If it's in a poor quality enclosure then it won't get very loud.

    Loud enough that you'd be deaf before the end of the song ...............
