I'm just wondering if anybody knows what the "Q factor" and Freq. is when setting up your EQ on the deck. I can definitely notice a difference when i tune it one way or the other, but I'm just wondering what exactly they are for? Like is there better settings depending on speaker capabilities ect. I'm sure there must be other decks besides Kenwood that have this, but I've only ever owned Kenwood decks lol. Any info would be awesome!
