Dual Subs set up advice

Can anyone give me some advice on best practice to run dual subs? I have two Martin Logan Descent i subs for a strictly two channel system with ML Prodigy mains.

My options are:
Speaker level in
RCA in (sub has both left and right in for single sub use)
Balanced XLR (LFE)in (only one XLR in)

I am running the Sonic Frontiers Line 3 which has both balanced and SE outputs.

As of now, I am running them from the 2nd post on my Krell 300M amps but was wondering if it would be just as well to run SE (rca) left out from preamp to left sub in and vice versa for the right. Or, go balanced #2 outs (balanced #1s used for amps) to the single (XLR) LFE in on the subs.

Thoughts opinions?

Scousepasty, so to understand you... you feed from the high voltage speaker terminal to the low voltage RCAs on the subs? Or do you mean you run RCAs to the amp and you Y off them to the RCAs on the subs? Or...from the high voltage speakers post you run to the speaker level in on the subs...

At the moment, I run them like the the last option via high voltage but thought it would be just as well to run RCA from the preamp.

Scousepasty, you have RCA jacks on your speakers? Do you mean you run lines in parallel from your speaker input terminals to the speaker level in on the sub?

The way I am running my cables is essentially the same, in parallel.
