battery question

[sidetracked3]

I am about to install a new stereo system in my boat and was wondering what the best battery to buy for this. I plan on running 2 batteries with this system. What do you guys think or recommend? TIA

Generally if your going to run dual batteries and wire them together for charging and usage you want Identical batteries.

If its not possible then you at least want the same make up,

ie: CCA, Gell or Lead Acid, that sort of thing.
