Little help with DC Audio Master/Slave and wiring to dual 1 ohm

Looking at buying another DC 2k to run my Fi SP4 v2+ 15 Dual 1 ohm

 

- Now I read through DC's manual and have a couple questions.

 

- DC amps don't generally like seeing below 1 ohm, now if I strap them at 2 ohms each amp will see 1 ohm.

1. Knowing this: Do I wire my subwoofer any differently? As in, would I wire my subwoofer in parallel for a 0.5 nominal load or in series for a 2 nominal load?

- Leaning towards wiring in series as that would get me to 2 ohms at the subwoofer, and 2 ohms at both amps (and finally 1 ohm at each amp). Is this correct?

 

2. Also what kind of RCA do you guys recommend for the single channel run between the two amps? Most come only in a 2 channel pairing.

The remaining #1 voice coil negative and #2 voice coil positive need a jumper between them. That will put you in series for a 2ohm final. As far as the strapping RCA, I believe Sky High offers a single RCA option for strapping, but I haven't looked at their site for a long time
