Terminating AQ Bedrock cables

I have, several times. If you looked at AQ's site, you'd see that these flat, double-quad cables have 4-different-size conductors in them, in 2 bundles. The 'bass' bundle contains 16 and 19g. pairs, while the 'treble' bundle contains 18- and 21g. pairs. (Gibraltar contains all Perfect Surface Copper+, while the other 3 cables contain combinations of long-grain copper, Perfect Surface Copper, and PSC+.)

If you were biwiring, you'd keep those bundles separate. Since you're single wiring, combine all the blacks for common and all the reds for positive.
.

Exactly right. With newer versions of AQ cable the individual strands are commonly labled as treble and bass with black strands marked likewise to facilitate biwiring. If you don't intend to biwire then simply divide and terminate. If you intend to solder the wires to terminal be sure and crimp first to ensure a good physical connection. Very simple process.
