I had a set of kicker cs 6.75" for the rear of my f150 that I never got around to installing. Decided to order a set of these as well to compare. I won't poopoo the kickers, they were a perfectly serviceable speaker but these are half the price, have a substantially larger magnet and a 1" tweeter vs the 1/2" tweeter in the kicker. I hooked both sets and it's a no brainer to keep the skars. They are currently being powered by a 50x4 kicker amp that comes in the powerstage kit with their subwoofer but I am in the process of taking that out and putting 6 evl 6.5s under the rear seat with an sk1500 and an sk100.4 for all the door speakers.
Could not be happier with my 4 EVL-65s. Very surprised by the lows and how much air they move.
Got 4 evl 6.5s in a downfiring behind the seat sealed truck box in my 91 reg cab Silverado wired at 1 ohm
