Just curious to see what amplifier(s) you are running in your boat and what you are powering with them. May as well mention battery setup as well. Over the winter I'll be upgrading the stereo to 4 Hollow Point 770 tower speakers and 6 new cabin speakers (choices - Polk db651, Hollow Point 6.5 coax, or Wetsounds 650), 10" JL sub. Using 2 JL G1300 amps for the tower and a JL G6600 for everything else. Already have a two battery setup and will upgrade the second battery to a Kinetik 2000 or 2400.
