I'm putting a car stereo into my jetboat. I'll be running an Ultimate
T3500D amp and a new Type R 12. My boat has a done up Oldsmobile 455 motor with the stock vehicle alternator. I also have 1 deep cell battery.
Will this be sufficient to keep my amp up and running?

Also what do I do for a ground to my amp? The amp will be up front for obvious reasons. So do I just run a 10 ft power and a 10 ft ground back to my battery?
And can I run the power and ground side by side or is that a no no?

Thanks.
