[QUOTE="gunz4me, post: 5527968, member: 596464"] Keep in mind that when you use a DMM to set your gains, it is not a means to an end, but designed to get you in the ball park. In most cases, you will still have to fine tune your gains a little to achieve optimum results. Using an oscilloscope would let you know if you were clipping with that particular test tone, but you would still have to fine tune everything by ear to blend your sub, mids, and highs together properly! Also, you generally set the gains when using a DMM with your speakers DISCONNECTED so that you do not blow them. Running a test tone will be extremely hard on your amp and speakers should you choose to leave them connected while you are putzing around with the gain. I have seen a couple of people do this and fry their speakers in the process. Where is the zero point on your subwoofer out? I know on my Alpine CDA-9885s that 15 is the "zero" point and anything under 15 on the sub is a cut to the subwoofer output. As a result, I set my gain with the subwoofer out @ maximum volume, or 15 in this particular case with the main volume at level 26. [/QUOTE]
