Running larger battery charger cables

william reynolds

I'm replacing my 50 amp Dolphin charger with a 100 amp Dolphin charger. The larger charger requires larger cables. Past posts have addressed the issue and no one 
has come up with a suggestion on running new cables through the present cable duct which is filled with some very hard material. I would like to hear form anyone who has   attempted  rerunning cables through the existing ducting.
