Some people hate these comps but once you listen to them in active mode, they are literally transformed. The factory passive crossover cut the mid a bit too high and the tweets a bit too low making them sound a bit harsh. If used without them, you realize they are worth more than you pay for them.
The wiring you see on the Fusion amp is not visible as the pic was taken when I was testing it before install. All the wiring is hidden under the carpet and center console, you can`t see any wires even though the seats are pushed all the way forward in the pic, you can barely see the amps when the seats are in normal position.
