I see now. Yea I was thinking about adding the line level converters. I'm not sure yet. I have the gain up about 25% on the amp. I'm willing to bet that's pushing it to produce 80%-90% of its RMS power since its a line level input. I think what I did hit the sweet spot.No, only if you add a line level converter before the amp. Sorry, my post was confusing... There are inexpensive ones like the Kicker or premium like the LC2i...
I'm not saying the line level converter is needed, just said that it's something I would consider at this point. Lots out there running the high level inputs in stereo and it's working great.
