I have seen 1400's in those cars, but I dont know if they changed brackets to make it fit or not. One of the best systems I seen and heard had 1 up front and a 600 by each amp.
I was talking about Auto media. Many batteries have screw on terminals you could even use a bolt and terminal rings. Stinger, kinetik, bat cap, spl cell, DC, Odyssey and many others have many terminal options.
