Amp in lounge... Amp in kitchen... can I link the two?

Not sure how to word what I want to do.. so here goes

I have an amp in the lounge and one in the kitchen.

Yamaha RX-V681



Onkyo TX-NR626



How would I go about connecting the amp in the lounge so music playing on that goes through to the kitchen amp and the speakers connected to it? Hope that makes sense.

I assume the Zone 2 zone out on the yamaha will do the job?

Cable run will need to be about 70 metres, would this be a problem for average RCA cables?

Thanks.

Thanks for the input.

I know 70m sounds long but that is taking into account running from where the amp is, along skirting, up walls, down walls, through walls etc. Maybe not 70m but definitely no less than 50m. Definitely not a big house but running cable tidily and the layout does make it a long run.

The purpose is so can play music from one source and not have to miss out when going to the kitchen or play from two different sources.
