I have 2 12"JL audio 12w0 subs and a Kenwood Excelon amp. For 2 Ohm mono my amp is rated at 400 watts RMS. That rating is at 12 volts, so i am sure i am getting a little more. Is my system big enough I would see any benifit from a capacitor. If so what size would I need? 1/2 farad? 1 farad? I just didnt know if a cap is recommended for any system or only bigger systems. Thanks
