Connecting a sub to a vintage integrated amp

I have a vintage Yamaha CA- 2010 integrated amp and am looking to add a small sub (perhaps a PBS Subseries 100) to my system. I have EPOS Mi5 speakers. The rear panel on my amp has PRE OUT and MAIN IN terminals with switches (on/off for the PRE OUT and Norm/DC for the MAIN IN). My question is, how do I properly connect the sub? The PBS sub has only a low level input RCA connector. Do I need to get a sub with high level inputs? Are there other considerations that I haven't asked about?

Thanks in advance for the advice.

I founds some on-line pics of your int amp and your proposed sub:

From the pics, it looks like what you can do is set the coupler switch on the back of the Yamaha to "off", then you would need a set of "Y" RCA adapters to plug to the L/R preouts on the 2010 to the main inputs to 'recouple' the pre and amp sections, and then run RCA cables to PSB line level inputs.
