hey q - I think what they meant was that adding an equalizer will give the amp a better signal, allowing better, cleaner power. I was running my three amps using one set of rca's from my head unit, with a bunch of y-splitters. The signal was weak to begin with, and was made much weaker by being split to so many amps. As a result, when i added my eq, with one set going in and three pairs going out, the signal was much stronger, so the gains didnt have to be set so high. The amp is just more efficient and the poewr is cleaner with better voltage outputs.
