Re: Which head-unit setting matter when setting gains with a DMM?o
For one you shouldn't be using loudness at all. For proper tuning you should have EVERYTHING on the Head Unit set flat BEFORE setting your gains. So that means loudness off, bass boost off, All EQ settings at 0, and depending on how your sub volume on the deck works you will either want it at 0 or maybe about half way up so you have room to adjust afterwards.

I always leave my system flat even after tuning and NEVER use loudness. It's the number one thing that's causing your clipping for sure. It's only meant to be used at lower volumes. The only thing I use after tuning to adjust the sub is the sub volume on the head unit because some songs have more bass than others so they need a little more or less.
What kind of amp/subs are you using? Maybe you just don't have the right setup to put out the kind of bass you're looking for
