no, you want a mono amp. Meaning one channel, then you wire the subs together. Will be a cleaner sound, you get a subsonic filter, and use less power to make the same wattage. Look for a 300-500wrms @ 2ohms rating from a quality amp.
the FSD audio amp i showed you its 700wrms at 1 ohm and around 500 at 2. So more then enough power for right now then later you can get bigger subs in single 2 ohm or dual 4 ohm and get 700 from the amp.
