[QUOTE="Neothin, post: 3026337, member: 567352"] Setup- AVIC-D2 NINe.1 NINe.2 eDi6500s comps 2x 10w6v2's So i finally got around to resetting the gains on my amplifiers this afternoon. about a month ago i installed an AVIC-D2 into my car, and havent had the time to reset gains. Previously I was running a stock headunit and a soundgate lineout converter that had 5v preouts. anyways, the thing that has me questioning... when i reset my gains, i actually had to turn them down to get to the proper voltage. This is weird because the lineout converter had 5v preouts while the D2 only has 2v preouts. I thought because of the lower signal voltage, i would actually have to turn the gains up. I didnt have to turn them down by a little.. the voltage on the sub amplifier when i first looked at it was 64.something! (which really has me worried, because i ran around for a month with the gain set way over what it's supposed to). all equalizer settings and such were completely flat on both headunits, so that idea can be thrown out. i used the DIY in the stickies above, and come up with 20.97v for the component amplifier (sqrt(110x4)) and 36.05v for the subwoofer amplifier (sqrt(1300x1)). the reasoning for using higher wattages in the equation was because the eD amps are rated @ 12.5v.... so i used the wattage that they would produce if output stayed linear @ 13.5v. anyone more knowledgeable than myself care to enlighten me as to why this happened?
