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!

Thank you all so much for the detailed information. It's hard to believe that in all these years, a guys has never used speaker-level inputs on a sub. The more you know... 
Hmm. This certain local seller does have two Sunfire MK2's, for sale. I like the stereo option!
