Hey steve - I say don't sweat it.

Yes the microscopic cross section of the RCA wire might be dropping your voltage a bit, but it's not otherwise altering the signal any more than the relatively large speaker wire is.

If the source is, say 15w rms into 4 ohms, that's nearly 8v, even if it's dropping a 1/2 volt (which it's not) you still have all kinds of signal strength to the JL inputs.

Why in the world would you want to connect 12 gauge speaker wire to an RCA?

I was unaware that this particular amplifier used the same input for either high or low level.  But if you are using a high-level input from a head unit, there is no need what so ever to use 12-gauge speaker wire as part of your interconnect.  18 AWG is the absolute largest I would use, and I'd also order the JL Audio interface kit as recommended above.

Or do it "right" and use an LOC rather than depending on the internal LOC.  But hey, if you don't want another component, at least order the proper plugs.
