[QUOTE="Patthehat033, post: 7677672, member: 637337"] You want to set the gain with the DMM based on the [B]*RMS*[/B] output of the amplifier. If you decide to set the gain based on your maximum output, you will most likely never hit that or fry your amplifier. Most lower quality amplifiers have a much higher "maximum" out put rating than rms rating. The maximum output will only occur when your head unit or receiver sends out a signal for a large bass note. Some higher quality amplifier's like Rockford, will tell you that they put out say 500 watts and will in reality put out about 1000wrms. So basically make sure you set your amplifier based on its rms output. [B]BUT[/B] also make sure you set your amplifier according to your subwoofer rating. If your subwoofer can handle 500rms and your amp can put out 600rms. Make sure you set your amplifier at 500rms not 600rms, or you will eventually fry it depending on the subwoofer, some are very under rated. You can either have the sub woofer hooked or unhooked. If you doing it while the subwoofer is unhooked, when you hook it back up make sure the voltage is near your desired voltage or do it again. Good luck. [/QUOTE]
