Think about the Weakest link!!!
Hey Chief -
A couple of things to think about. Razzman's comments are spot on. Dont even think about 1 battery... Get two. Kinetik stuff is good for sure but really take a look at the reserve capacity ratings. Get a deep cycle battery that can be run down again and again without being killed permanently.
As for the stereo, I cant tell you how many people that I talk to and they say the same thing," I just want to add this or that". Well sure thats the case today, but what about tomorrow. I tell guys to look at their stereo system in three area's
each of these area's will require different amounts of current draw. when it comes to adding bad ass gear, dont step up and buy nice stuff without first making sure you can support the electrical needs. SO IMPORTANT.
in simple terms, this is like managing to buy a new Ferrari but never take it out of first gear. Who wants that!
Just remember, your needs change over time. Go slow and have fun for now and next gear you can slam that stereo into 5th gear. peace!
