[QUOTE="CrAiZ3, post: 8447943, member: 569412"] Hello everyone, I just wanted to explain how I set the gain on my amp with a multi-meter and have someone tell me if I'm missing something. I've done this a bunch of times but something unusual happened this time. I did the normal: [LIST] [*]All speaker wires disconnected [*]Amp gain all the way down [*]Bass boost all the way down [*]Subsonic all the way down [*]LP all the way up [*]Calculated my voltage to be 34v. Amp is 1150rms with a 1ohm load [/LIST] When I was ready to go, I played a 50hz test tone @ 3/4 volume of my HU. For clarification my multi-meter is a Craftsman model [URL="http:////forums/usertag.php?do=list&action=hash&hash=82141"]#82141[/URL] and was set on Vac 200. Now, here is the weird thing that I've never encountered before when setting the gain on an amp. [B]I turned the gain all the way up and only hit ~26v, when my target was 34v[/B]. I had to add bass boost to get a reading of 34v on my multi-meter. I hooked the subs back up and did a test run at 1/2 volume and didn't notice any distortion with the bass boost. Now I don't know if this makes any difference, but I have a brand new car so I wanted to keep my factory HU and am using a Lineout converter with the settings relatively low. Any advice would be greatly appreciated. Thanks! [/QUOTE]
