That's no Fathom. That's JL's lowly w1 woofer. You need to get the real Fathom 13w7. It weighs in at feather weight 53 pounds. That would really screw up the weight distribution in a 1900 pound car. It's the exact same driver that's in the Fathom and the Gotham. I had one of these in my Civic and with JL 1000 mono amp. Impossible to stay in the car with the doors, closed.
For high end car audio, my choice would be McIntosh....wrapped in a Ford GT package. Other HE audio, unfortunately don't come as well equiped for high performance driving. Dynaudio/Volvo or Mark Levinson in the Lexi. Then there's no companies we love to hate who have branded car audio, in otherwise fine vehicles....Bang and Olufsen in the Audis and Bose in a gazillion vehicles good and bad. Harmon is very busy using their nameplates as well. But given the means, the absolute ultimate in both car audio and car performance goes to Bugatti/Burmester! I wonder if you subtract the entertainment system they'd knock off the price of the Exige.
Standard equipment still is the 1.8 litre super peaky Toy engine. The ultimate combination of awesome performance and reliability.
