[QUOTE="40oz, post: 8038802, member: 638225"] You can set gains by ear, multimeter, o-scope or something like the SMD DD1. Most people that have been into car audio a long time will recommend to set gains by ear but most people that are new to car audio are not comfortable with that as there is the possibility of clipping and damaging your equipment. The multimeter method will allow you to set your gains pretty close to where you want them even if it is not 100% accurate. The safest and probably most accurate way to set gains is to use an oscilloscope or DD1. There is a lot of different opinions about the DD1 though, some people swear by it and others say that they will never use one. You might be able to find someone in your area with an o-scope or DD1 and they can set your gains for a small fee ($5-$10). If not then you can buy a cheap multimeter(you might already have one or someone you know probably does) and set them that way. I've used all the methods I just mentioned but now I stick to setting my front speakers amp by ear and use a DD1 for sub amp. [/QUOTE]
