I got my choice of Cadence, Soundstream, PG, or Earthquake to power two RF Punch HE's in a vented box. The subs are 8ohms wired for a 4ohm load and require 400w RMS give or take. Any suggestions out of those 4. I just lost my Kicker ZR240 due to an accidental Arc during a car repair. I just want to try something new.
