If you're only using it for the stereo, you can get the marine battery (deep cycle). The reserve capacity is important if you plan to use the stereo when the motor isn't running. Their marine batteries also have high cold cranking amp numbers, too.

Jim, there are three or four different models of the blue top. Which one should I get or does it matter???

If you want a Blue Top, the D34M should do it. It has two types of battery terminal and isn't as large, physically. Their site has a "Find Your Battery" feature, too.
