I have a 330 Sun Sport that has the upgraded sound system from the factory that included two amplifiers, one for the cabin and one for the cockpit\. I'm upgrading the sound system and adding two tower speakers to the radar arch. To do this I'm upgrading one of the amplifiers to a 4 channel amp to accommodate the new channels. Can I use the same power cables going into the old amp for my new amp? I'd really prefer not to have to run new ones. My only concern is the new amp is 600w and the factory amp was 250w but I'm not sure if they sized the power cables so precisely for this to matter.
