I am currently redoing our system on our boat. I Previously was running a Q-series 12" kicker L7 DVC 4ohm, wired in parallel to 2ohms powered by a Hifonics BXX3000.1. I am now upgrading my sub, and switching out the kicker and installing two 12" U series Sundown DVC 4ohms, in a custom made 4cubed box(after sub/port displacement) with two 4" aeroports 13" long each. I am going to run them in parallel to get them to a 1 ohm load, and curious how best to get power. Should I continue to run off the Hifonics BXX3000.1 at 1ohm? Or should I get a second BXX and strap them to give more of a head room? and if I strap do I keep them wired to 1ohm? or should I scrap the amp all together and get something with more power, and if so what? any input would be helpful, as I want to be able to push these subs to the limit, without smoking the coils, or thermalling out the amp.
