How Does a "HI-LEVEL IN" Affect Impedance Load?

I'm looking at adding a sub (possibly a used Sunfire MK2) to a 2-Channel integrated tube amp, with no pre-amp/sub outputs. Would it be ill-advised to connect (in parallel) the speaker outputs with the Hi-Level In, on the sub? What effect. if any, does this have on the impedance load? The currently-used (custom built) speakers run around 6-ohm, and the amplifier (Jolida) does have both 4, and 8-ohm terminals, for whatever that information is worth.  

Thanks!

It's a shame your Jolida SJ202a doesn't have line level "preamp output" to take to your subs line input, as I've always found that line level is tighter and more uncoloured for a sub than using the high level speaker output, even with SS amps.
I myself would put L&R rca preouts from the preamp circuit, on it if it were mine and I desperately needed subs
