thanks thumper420 for the parameters,if i have 750rm what db will i roughly make the same with 1000rms and with 1500rms

i would guess it would be louder, have you done your big 3 yet?

yes all done,im just trying to get a rough estimate of how many db's from 750 rms and from 1000 rms 1500rms,or how do i work it out

Too many variables to be sure, only way to find out is tune it up, fire it up and meter it.....:smokin:
