A capacitor won't do a single thing for a weak electrical signal. The problem here isn't the voltage. I can assure you that the system can handle more than 600W RMS. In fact, I am running 1000W RMS...on a class AB amp, pushing two 18s.I'm telling you brother, Ohm's Law... Its cutting out due to voltage drop, upgrade your wiring first, but if its still doing it then you need that additional power supply, and thus a capacitor.

Caps are a colossal waste of money. If you need more power, get a second battery.
