[QUOTE="FoxPro5, post: 5702597, member: 562649"] Which head unit do you have? You don't [I]need [/I]to set your gain if the preamp voltage is sufficient to drive the speakers to your desired loudness. A gain knob is a sensitivity attenuator that allows you to add voltage to the speakers. Always drive the system from the HU volume first and add only the amount of amp gain needed to run a sufficiently loud, but undistored sounding system. A DMM is usless in this regard as i cannot sense when the system is stressed. The "DMM method" is not even ballbark, it's outer space. Trust me, you ears a good enough....you just need to practice a little. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
