i had my gain at about 80-85%.. its from 9v-.2v.. i set it by ear.. but today i decided to set it by dmm with a 50 Hz test tone.. so i calculated that with 900w wired at 2 ohms i should be getting an output of 42.4v.. so i set my gain to 46v with the dmm
just hooked everything back up and it was a little quieter than before.. gain is at about 4.4-4.7v.. i have the output measured at 46v since i know you can set the gains higher with music than a test tone.. but can i still turn it up a little more?
and also.. when i calculated all of this with an online calculator my gain should have been at 2.36v in order to put out 900w with my hifonics 1208d wired at 2 ohms(see pic)
what could be affecting this? i had no load hooked up to the amp when i set my gain with the dmm but i read another thread on here saying that shouldnt matter..
