I purchased 75 amp Anderson Powerpole connectors and #6 flex speaker
cable from Debco Electronics for my extension cable. #6 fit easily. I
suspect even #4 would have fit, but I see no reason to get that large.

The 75 amp Powerpole connector is designed for 6, 8 or 10 AWG wire so
you
might have problems squeezing a larger wire in.

If it uses a 75 Amp PP connector, my inclination would be to use the
6AWG MINIMUM. I would be tempted to use the flexible welding cable
lead
stock in the largest gauge I could fit in the application space. I'd
trim down the end of the conductor to JUST fit into the 75 AMP crimp
contact. Then, I'd tine the trimmed down end to bond ALL the
conductors
together right at the end before I crimped/soldered. Then, I'd
crimp/solder the terminal on making sure not to be sloppy and cause a
fitment issue. If possible, I would put as many twists in the
red/black
leads between radio and power supply connection as possible....
I've not investigated the wiring yet, BUT, if there is a ground wire
between the PA chassis and the PS chassis, I would integrate the ground
wire into the power harness in a 3-wire bundle with all three wires as
close to the same length and shinked into a single cable.
But I'm nuts... <smile>

What gauge wire is used for the HV line between the power supply and
amp?
I'd like to build or source a shorter cable.
