Ok I've finally decided on what subs to get and I'm going with 4 15's but having trouble deciding on an amp set up. There are Max 2000 watt and RMS at 1000 watt (subs) I've been using Hifonics but am up to suggestions as what to use as I've only ever used Hifonics, Kicker, JL, or Rockford Amps. Dont know much about the new companys so thoughts would be greatly appreciated!
