Personally wouldn't pay the price for the RE extra X models. Much better can be had for less. Have you looked at the Skar VVX series? The v1's are proven subs that will definitely take that
Power and sound good doing it. The v2's are about to be in stock on March 6th and have many upgrades from the v1's but still keep the same great price. PM BigBoi on here for anything Skar related and he get get you hooked up with the best pricing.
