I was thinking of putting in a sub I have laying around. Should I go with two batteries, or just be cautious when using the sub.

I have 3 on mine, 2 on a two battery switch switch for the engine+accesories and 1 for the radio+amps+sub+dvd+lcd on a seperate switch where I can tie it into the main batteries or seperate it completely. Maybe overkill but I can leave the system on all day without worrying about it starting.. :)

The sub won`t drain your battery, but the AMP that powers the sub will drain it. I think you should always have 2 batteries on a boat - with switch of course.

I'd go with one cranking battery, and one deep cycle. But, I only run one so what do I know? :laugher:

I don't use my stereo or lights much so I've never had any issues with just one.

Dont get me wrong Optima Batteries are great but for the price they dont last as long as they should. I picked up two Stowaway batteries this spring for 120 bucks. If they last 2 years thats fine. I'll just replace them again for another 120 bucks. I will take newer regular wet cell batteries over older gel cell any day.

Always go with a switch and I use an on board charger (dual bank) keep it plugged all the time and my battery problems have become a thing of the past. Even running amps for stereos cranked up for 6 plus hours at a time
