Hi icehawk21

If it were me I'd go with option #2. Since you're already using the RCA connection using a RCA to XLR cable will not be any different.

It's the cheapest solution and it'll work just like it is now.

But I'd still check with Axiom as to whether you could replace or fix your current Sub's input.
