Hi,
I'm just building my first hifi and recently got a Yamaha AS-501 amp which I have connected to an old pair of Sony speakers (SS-H900) as I cant afford new speakers just yet. The amp can power two sets of speakers and as mine are missing a bit of bass, I was thinking of adding on a pioneer sslw500 passive sub I found in the sale.
The issue is with the amp's impedance switch with settings as follows:
A or B - 4ohm low, 6 ohm high
A+B - 8ohm low, 12ohm high

My speakers have 6ohm impedance (and 160W power rating), so with just them wired up I'm fine with the high setting. If I have A connected to my 6ohm speakers and B connected to this passive amp which impedance setting should I choose?
Even the low setting for A+B is above my speakers, but if that is split across the channels do I still need high to get 6ohms to the A channel?
Thank you very much in advance.
