I bought a boat that was built from the factory without a head unit or any speakers.
I bought a Head Unit, Amp and Speakers to install in the boat and have a couple questions.
I am going to run a hot wire from the battery to a switch on the dash then to the head unit. What gauge wire should i use for that and what size switch? Will any switch work or should i be looking for something specific?
I also wanted to know if i could ground the head unit to the amp since i am running a ground wire from the amp to the Battery. If not i can run a ground from the head unit to the Battery but what gauge wire should i use?
These may be silly questions but im just not 100% on what i should do.
