I am having all new amps put in my boat a total of 3 with 1500 watts rms my installer said he will not run d blocks. He runs seprate power and ground for each amp is this common and what are the benifets?
E-ll is the chapter in the ABYC standards that covers electrical installations. Your description made it sound as though he was going to run six conductors to the battery terminals. If that were the case then it would be problematic.
