THX_Elite posted a topic in Subwoofers / SpeakersThe Fi BTL NEO that I ordered has a 2ohm Re rating of 1.8 so wiring in parallel i should be at .9ish ohms before possible box rise and any damping factors. I bought the AA 3800.1D and just purchased a North Star AGM31 for the back. I know my box is built to spec, tuned at 32hz, braced like a champ and stiff as humanly possible...here is my question/concern... I just want to understand as much as i can without getting overly technical on ohm's and voltage vs impedance and it's variance...As a daily listener I'm just looking more about what power I will be feeding this sub while wired to "1" ohm around 13.5v...I just hope I don't fall into some 3 ohm situation after all is factored in where I would be feeding the 2500rms sub a measly 1k or something like that Ampere Audio's website specs for the AA 3800 1.D specs at 12.8v Power 12.8 VDC – 1 ohm: 3,500W RMS. Power 12.8 VDC – 2 ohm: 1,800W RMS. Power 12.8 VDC – 4 ohm: 900W RMS. SSA's website specs for the AA3800 1.D specs at 14.4v Power 14.4 VDC - 1 ohm: 3,800W RMS Power 14.4 VDC - 2 ohm: 2,000W RMS Power 14.4 VDC - 4 ohm: 750W RMS The main reason I ask is because I will have spent over 2,000 dollars in trying to achieve 1k more RMS and definately more output. And secondly, I want to make sure I get the best performance out of my new upgrades ...Should I forget about all the numbers where as I am only a daily listener and not a competitor? And even more so, can I reasonably expect that I will have a significant increase in output going from a 1500rms Fi BL 12" running on a 1600rms Hifonics amp to a 2500rms Fi BTL NEO runnin on a 3800rms Ampere Audio?
