If someone ships me one I can test it, would have to run it as 2ch bridged tho since I only have one bucket and don't feel like making another.

Then you get the SP amp with the connectors wired as 1+1 and 2+2. Your cables will have speakons on each end, going from 1+ to 1+, 1- to 1-, 2+ to 2+, 2- to 2-. Wiring up this way puts the drivers in parallel to the amp, so you present it with a 2 ohm load.
Thanks guys. I appreciate all the advice here the past couple of days. I took your suggestion and order the SP-12000-DP. They are making it with the HT fans and HT version firmware, but the DP chasis. I ordered with the CH1+CH1 CH2+CH2 wiring option. I will configure the dual 2ohm voice coils in each of the HST-18 in series to make them a 4 ohm load, then a pair of subs on channel 1 and the other pair on channel 2 (as I understand it the amp takes care of "Y" split for me to do this) to deliver 3,000 watts to each sub. Looking forward to receiving it. In the meantime I'm busy building my subwoofer cabinets.

Word is Noty plugged it in last night and is waiting for the caps to fully charge. Once the lights stop dimming we should have fresh amp pron! 😈

prelim results, will do more comprehensive tests when I get more time.

Measuring Amplifiers

I tested the enhanced fp14000 a bit in bridged mode into 4.4 ohms, bursts very similar to the Sanway fp14000, though a touch less, however it seems to have improved efficiency and better sustained output. Looking like a winner so far. The fans are noisy as expected.
