Im thinkin 2 HX2's..not the 2000 watt sub but the other ones. They say they can handle 500 rms and the amp i got is 1100 watts with 2 channels.. ill have about 550 watts ruining into each sub with a ported plexi glass box.. im also thinking about getting a digital 1 farad cap.. do you think this system is good a good starters system..do you think it will be loud... I need all your opions cause i sitll cant really decide on subs but i think those would be perfect for the amp i got.
