Ok, Im going to build a fiberglass box.....done a few in the past, but far from an expert (ill have some help). Anyways, Im going to try building around a 12" Fi, and probably a Hifonics BXi2006D = 2000watts @ 1ohm. I will be mostly running the sub for short periods, 30 minutes or less. There will be rare times when I take a trip and will be running the sub for longer periods.....but most likely not at full blast. Im leaning towards LSQ for the most part, but SPL is important as well. Which sub would you recommend, and which options? PS. I live in Northern California.....we get 100+ degree days, but normally when it is that hot, i wont run my stereo very loud, as i run the A/C.
