Ok so My Kenwood has active crossovers and "DTA". I can keep my front and rear preouts or I can change it to a "3way" system. Where Tweets, Mids, Sub are my preouts. Theres no more Front and Rear Fade and DTA at that point. I was thinking of doing this and getting a 4 channel amp. Yet I like the DTA and some of the other features. Is there any benefits to a "3way" system opposed to having traditional front, rear , sub preouts?
