[QUOTE="fatboytyler, post: 8363627, member: 658624"] What are you talking about? That formula is what is needed to set gains via multimeter. Using a clean test tone (I like -3 DB so I induce very slight clipping here and there) or some of your regular music you will put the multimeter leads on the speaker leads without the speakers plugged in, head unit volume at 75% with all EQs flat/off, you'll start turning your gain up until you reach your desired voltage. Few things to note though... Your HU preout voltage needs to be 2+ Volts to be suitable. Your multimeter is likely not high end enough to accurately get a voltage reading on music because of the extreme and sudden drops so a test tone might be better. Your Lowpass filter needs to be set according to your box tuning. I would suggest aiming for the 34.0 to 34.5 range to help reduce chances of clipping and make sure you double check your numbers (I didn't, but make sure). [/QUOTE]
