With single wire (A channel only), I would guess that a gauge ~10 (2.5 mm diameter) would be OK. With bi-wiring (LF on A channel, HF on B channel), should I run two gauge ~10 cables to each speaker so total of 5 mm Cu, or could I also use a dual gauge 16 (1.3 mm), so total of 2.6 mm. Gauge 16 on its own is be a bit thin, but doubling up would correspond to a gauge 10 wire. Or split the difference in middle and go for gauge 14 (2x 1.6 mm = 3.2 mm = gauge 8)?
A and B speaker outputs are for two sets of speakers not biwiring. So your cable should go from set A or set B.so your speaker cable if bi wire should have two connections amp end and four connections speaker end
