[QUOTE="OKAY, post: 8438714, member: 663582"] I started a thread couple hours ago with the same question then seen this one. Except my HU is a DDX771 and its sub level is -50 to +10. For what reason did they decide to step it back an extra -35 to -40?. Anyways, theirs a youtube with a dd-1 at one of the preouts on a DDX-6021 - distortion began at 32/35. Subwoofer level range from -10 to +10 on this model. When the test was made sub level was +10. So looks like the usual: attenuate the sub level volume and at max (+10db) level you only get the full 4v. But, for months my gain was set with a max +10 sub level, also and always been clueless and wondering why a DDX771 went back as far as -50 and max being +10. Finally, I reset the gain by dmm, this time lowering the sub level down to +6 and I hear a big difference their louder and especially the bass notes feel and sound much lower just the way I think bass should sound. Im pretty new and have only heard other peoples systems back in the day and I hated the fact mine seemed to be missing the deep bass that everyone else had. Dont know wtf if I was distorting the entire time with a maxed out sub level but now they sound much cleaner n louder. Amp gains are 25/100 now before they were about 18/100. I'm going to try 0db now. My setup is two hds315 with a cx1200.1 kicker on each sub. Matching the gains on both amps can get crazy. I think the vibration over time bumps one of the gain dials by a hair and sheesh bcomin out a phase and sheesh. So i set gains several times a month lol [/QUOTE]
